OADP features and plugins OpenShift API for Data Protection (OADP) features provide options for backing up and restoring applications. The default plugins enable Velero to integrate with certain cloud providers and to back up and restore OpenShift Container Platform resources. 4.2.1. OADP features OpenShift API for Data Protection (OADP) supports the following features: Backup You can back up all resources in your cluster or you can filter the resources by type, namespace, or label. OADP backs up Kubernetes objects and internal images by saving them as an archive file on object storage. OADP backs up persistent volumes (PVs) by creating snapshots with the native cloud snapshot API or with the Container Storage Interface (CSI). For cloud providers that do not support snapshots, OADP backs up resources and PV data with Restic. Restore You can restore resources and PVs from a backup. You can restore all objects in a backup or filter the restored objects by namespace, PV, or label. Schedule You can schedule backups at specified intervals. Hooks You can use hooks to run commands in a container on a pod, for example, fsfreeze to freeze a file system. You can configure a hook to run before or after a backup or restore. Restore hooks can run in an init container or in the application container. 4.2.2. OADP plugins The OpenShift API for Data Protection (OADP) provides default Velero plugins that are integrated with storage providers to support backup and snapshot operations. You can create custom plugins based on the Velero plugins. OADP also provides plugins for OpenShift Container Platform resource backups and Container Storage Interface (CSI) snapshots. Table 4.1. OADP plugins OADP plugin Function Storage location aws Backs up and restores Kubernetes objects by using object store. AWS S3 Backs up and restores volumes by using snapshots. AWS EBS azure Backs up and restores Kubernetes objects by using object store. Microsoft Azure Blob storage Backs up and restores volumes by using snapshots. Microsoft Azure Managed Disks gcp Backs up and restores Kubernetes objects by using object store. Google Cloud Storage Backs up and restores volumes by using snapshots. Google Compute Engine Disks openshift Backs up and restores OpenShift Container Platform resources by using object store. [1] Object store csi Backs up and restores volumes by using CSI snapshots. [2] Cloud storage that supports CSI snapshots Mandatory. The csi plugin uses the Velero CSI beta snapshot API . 4.2.3. About OADP Velero plugins You can configure two types of plugins when you install Velero: Default cloud provider plugins Custom plugins Both types of plugin are optional, but most users configure at least one cloud provider plugin. 4.2.3.1. Default Velero cloud provider plugins You can install any of the following default Velero cloud provider plugins when you configure the oadp_v1alpha1_dpa.yaml file during deployment: aws (Amazon Web Services) gcp (Google Cloud Platform) azure (Microsoft Azure) openshift (OpenShift Velero plugin) csi (Container Storage Interface) kubevirt (KubeVirt) You specify the desired default plugins in the oadp_v1alpha1_dpa.yaml file during deployment. Example file The following .yaml file installs the openshift , aws , azure , and gcp plugins: apiVersion: oadp.openshift.io/v1alpha1 kind: DataProtectionApplication metadata: name: dpa-sample spec: configuration: velero: defaultPlugins: - openshift - aws - azure - gcp 4.2.3.2. Custom Velero plugins You can install a custom Velero plugin by specifying the plugin image and name when you configure the oadp_v1alpha1_dpa.yaml file during deployment. You specify the desired custom plugins in the oadp_v1alpha1_dpa.yaml file during deployment. Example file The following .yaml file installs the default openshift , azure , and gcp plugins and a custom plugin that has the name custom-plugin-example and the image quay.io/example-repo/custom-velero-plugin : apiVersion: oadp.openshift.io/v1alpha1 kind: DataProtectionApplication metadata: name: dpa-sample spec: configuration: velero: defaultPlugins: - openshift - azure - gcp customPlugins: - name: custom-plugin-example image: quay.io/example-repo/custom-velero-plugin 4.3. Installing and configuring OADP 4.3.1. About installing OADP As a cluster administrator, you install the OpenShift API for Data Protection (OADP) by installing the OADP Operator. The OADP Operator installs Velero 1.7 . Note Starting from OADP 1.0.4, all OADP 1.0. z versions can only be used as a dependency of the MTC Operator and are not available as a standalone Operator. To back up Kubernetes resources and internal images, you must have object storage as a backup location, such as one of the following storage types: Amazon Web Services Microsoft Azure Google Cloud Platform Multicloud Object Gateway S3-compatible object storage, such as Noobaa or Minio Important The CloudStorage API for S3 storage is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope . You can back up persistent volumes (PVs) by using snapshots or Restic. To back up PVs with snapshots, you must have a cloud provider that supports either a native snapshot API or Container Storage Interface (CSI) snapshots, such as one of the following cloud providers: Amazon Web Services Microsoft Azure Google Cloud Platform CSI snapshot-enabled cloud provider, such as OpenShift Container Storage If your cloud provider does not support snapshots or if your storage is NFS, you can back up applications with Restic . You create a Secret object for your storage provider credentials and then you install the Data Protection Application. 4.3.1.1. Configuring NooBaa for disaster recovery on OpenShift Container Storage If you use cluster storage for your NooBaa bucket backupStorageLocation on OpenShift Container Storage, configure NooBaa as an external object store. Warning Failure to configure NooBaa as an external object store might lead to backups not being available. Procedure Configure NooBaa as an external object store as described in Adding storage resources for hybrid or Multicloud . Additional resources Overview of backup locations and snapshot locations in the Velero documentation . /// Module included in the following assemblies: 4.3.1.2. About OADP update channels When you install an OADP Operator, you choose an update channel . This channel determines which upgrades to the OADP Operator and to Velero you receive. You can switch channels at any time. There are three update channels: The stable channel contains the latest minor updates (y-stream updates) and patches (z-stream updates) of OADP ClusterServiceVersion`. As each new release is published, the available ClusterServiceVersion of the OADP Operator will be appended with the latest available minor patch. The stable-1.0 channel contains oadp.v1.0. z , the most recent OADP 1.0 ClusterServiceVersion . The stable-1.1 channel contains oadp.v1.1. z , the most recent OADP 1.1 ClusterServiceVersion . Which update channel is right for you? Choose the stable update channel to install the latest stable OADP version and to receive both minor updates and patches. If you choose this channel, you will receive all y-stream and all z-stream updates for version x.y.z . Choose the stable-1. y update channel to install OADP 1. y and to continue receiving patches for it. If you choose this channel, you will receive all z-stream patches for version 1. y . z . When must you switch update channels? If you have OADP 1. y installed and you want to receive patches only for that y-stream, you must switch from the stable update channel to the stable-1. y update channel. You will then receive all z-stream patches for version 1. y . z . If you have OADP 1.0 installed, want to upgrade to OADP 1.1, and then receive patches only for OADP 1.1, you must switch from the stable-1.0 update channel to the stable-1.1 update channel. You will then receive all z-stream patches for version 1.1. z . If you have OADP 1. y installed, with y greater than 0, and want to switch to OADP 1.0, you must uninstall your OADP Operator and then reinstall it using the stable-1.0 update channel. You will then receive all z-stream patches for version 1.0. z . Note You cannot switch from OADP 1. y to OADP 1.0 by switching update channels. You must uninstall the Operator and then reinstall it.

For CSI snapshots, you must create a VolumeSnapshotClass CR to register the CSI driver. You must have a volume location configured in the DataProtectionApplication CR. Procedure Retrieve the backupStorageLocations CRs by entering the following command: USD oc get backupStorageLocations Example output NAME PHASE LAST VALIDATED AGE DEFAULT velero-sample-1 Available 11s 31m Create a Backup CR, as in the following example: apiVersion: velero.io/v1 kind: Backup metadata: name: <backup> labels: velero.io/storage-location: default namespace: openshift-adp spec: hooks: {} includedNamespaces: - <namespace> 1 includedResources: [] 2 excludedResources: [] 3 storageLocation: <velero-sample-1> 4 ttl: 720h0m0s labelSelector: 5 - matchLabels: app=<label_1> - matchLabels: app=<label_2> - matchLabels: app=<label_3> orlabelSelectors: 6 - matchLabels: app=<label_1> - matchLabels: app=<label_2> - matchLabels: app=<label_3> 1 Specify an array of namespaces to back up. 2 Optional: Specify an array of resources to include in the backup. Resources might be shortcuts (for example, 'po' for 'pods') or fully-qualified. If unspecified, all resources are included. 3 Optional: Specify an array of resources to exclude from the backup. Resources might be shortcuts (for example, 'po' for 'pods') or fully-qualified. 4 Specify the name of the backupStorageLocations CR. 5 Backup resources that have all of the specified labels. 6 Backup resources that have one or more of the specified labels. Verify that the status of the Backup CR is Completed : USD oc get backup -n openshift-adp <backup> -o jsonpath='{.status.phase}' 4.4.1.2. Backing up persistent volumes with CSI snapshots You back up persistent volumes with Container Storage Interface (CSI) snapshots by creating a VolumeSnapshotClass custom resource (CR) to register the CSI driver before you create the Backup CR. Prerequisites The cloud provider must support CSI snapshots. You must enable CSI in the DataProtectionApplication CR. Procedure Create a VolumeSnapshotClass CR, as in the following examples: Ceph RBD apiVersion: snapshot.storage.k8s.io/v1 kind: VolumeSnapshotClass deletionPolicy: Retain metadata: name: <volume_snapshot_class_name> labels: velero.io/csi-volumesnapshot-class: "true" snapshotter: openshift-storage.rbd.csi.ceph.com driver: openshift-storage.rbd.csi.ceph.com parameters: clusterID: openshift-storage csi.storage.k8s.io/snapshotter-secret-name: rook-csi-rbd-provisioner csi.storage.k8s.io/snapshotter-secret-namespace: openshift-storage Ceph FS apiVersion: snapshot.storage.k8s.io/v1 kind: VolumeSnapshotClass metadata: name: <volume_snapshot_class_name> labels: velero.io/csi-volumesnapshot-class: "true" driver: openshift-storage.cephfs.csi.ceph.com deletionPolicy: Retain parameters: clusterID: openshift-storage csi.storage.k8s.io/snapshotter-secret-name: rook-csi-cephfs-provisioner csi.storage.k8s.io/snapshotter-secret-namespace: openshift-storage Other cloud providers apiVersion: snapshot.storage.k8s.io/v1 kind: VolumeSnapshotClass metadata: name: <volume_snapshot_class_name> labels: velero.io/csi-volumesnapshot-class: "true" driver: <csi_driver> deletionPolicy: Retain You can now create a Backup CR. 4.4.1.3. Backing up applications with Restic You back up Kubernetes resources, internal images, and persistent volumes with Restic by editing the Backup custom resource (CR). You do not need to specify a snapshot location in the DataProtectionApplication CR. Important Restic does not support backing up hostPath volumes. For more information, see additional Rustic limitations . Prerequisites You must install the OpenShift API for Data Protection (OADP) Operator. You must not disable the default Restic installation by setting spec.configuration.restic.enable to false in the DataProtectionApplication CR. The DataProtectionApplication CR must be in a Ready state. Procedure Edit the Backup CR, as in the following example: apiVersion: velero.io/v1 kind: Backup metadata: name: <backup> labels: velero.io/storage-location: default namespace: openshift-adp spec: defaultVolumesToRestic: true 1 ... 1 Add defaultVolumesToRestic: true to the spec block. 4.4.1.4. Using Data Mover for CSI snapshots Important Data Mover for CSI snapshots is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope . The OADP 1.1.0 Data Mover enables customers to back up container storage interface (CSI) volume snapshots to a remote object store. When Data Mover is enabled, you can restore stateful applications from the store if a failure, accidental deletion, or corruption of the cluster occurs. The OADP 1.1.0 Data Mover solution uses the Restic option of VolSync. Note Data Mover supports backup and restore of CSI volume snapshots only. Currently, Data Mover does not support Google Cloud Storage (GCS) buckets. Prerequisites You have verified that the StorageClass and VolumeSnapshotClass custom resources (CRs) support CSI. You have verified that only one volumeSnapshotClass CR has the annotation snapshot.storage.kubernetes.io/is-default-class: true . You have verified that only one storageClass CR has the annotation storageclass.kubernetes.io/is-default-class: true . You have included the label velero.io/csi-volumesnapshot-class: 'true' in your VolumeSnapshotClass CR. You have installed the VolSync Operator by using the Operator Lifecycle Manager (OLM). Note The VolSync Operator is required only for use with the Technology Preview Data Mover. The Operator is not required for using OADP production features. You have installed the OADP operator by using OLM. Procedure Configure a Restic secret by creating a .yaml file as following: apiVersion: v1 kind: Secret metadata: name: <secret_name> namespace: openshift-adp type: Opaque stringData: RESTIC_PASSWORD: <secure_restic_password> Note By default, the Operator looks for a secret named dm-credential . If you are using a different name, you need to specify the name through a Data Protection Application (DPA) CR using dpa.spec.features.dataMover.credentialName . Create a DPA CR similar to the following example. The default plugins include CSI. Example Data Protection Application (DPA) CR apiVersion: oadp.openshift.io/v1alpha1 kind: DataProtectionApplication metadata: name: velero-sample namespace: openshift-adp spec: features: dataMover: enable: true credentialName: <secret_name> 1 backupLocations: - velero: config: profile: default region: us-east-1 credential: key: cloud name: cloud-credentials default: true objectStorage: bucket: <bucket_name> prefix: <bucket_prefix> provider: aws configuration: restic: enable: <true_or_false> velero: defaultPlugins: - openshift - aws - csi 1 Add the Restic secret name from the step. If this is not done, the default secret name dm-credential is used. The OADP Operator installs two custom resource definitions (CRDs), VolumeSnapshotBackup and VolumeSnapshotRestore . Example VolumeSnapshotBackup CRD apiVersion: datamover.oadp.openshift.io/v1alpha1 kind: VolumeSnapshotBackup metadata: name: <vsb_name> namespace: <namespace_name> 1 spec: volumeSnapshotContent: name: <snapcontent_name> protectedNamespace: <adp_namespace> resticSecretRef: name: <restic_secret_name> 1 Specify the namespace where the volume snapshot exists. Example VolumeSnapshotRestore CRD apiVersion: datamover.oadp.openshift.io/v1alpha1 kind: VolumeSnapshotRestore metadata: name: <vsr_name> namespace: <namespace_name> 1 spec: protectedNamespace: <protected_ns> 2 resticSecretRef: name: <restic_secret_name> volumeSnapshotMoverBackupRef: sourcePVCData: name: <source_pvc_name> size: <source_pvc_size> resticrepository: <your_restic_repo> volumeSnapshotClassName: <vsclass_name> 1 Specify the namespace where the volume snapshot exists. 2 Specify the namespace where the Operator is installed. The default is openshift-adp . You can back up a volume snapshot by performing the following steps: Create a backup CR: apiVersion: velero.io/v1 kind: Backup metadata: name: <backup_name> namespace: <protected_ns> 1 spec: includedNamespaces: - <app_ns> storageLocation: velero-sample-1 1 Specify the namespace where the Operator is installed. The default namespace is openshift-adp . Wait up to 10 minutes and check whether the VolumeSnapshotBackup CR status is Completed by entering the following commands: USD oc get vsb -n <app_ns> USD oc get vsb <vsb_name> -n <app_ns> -o jsonpath="{.status.phase}" A snapshot is created in the object store was configured in the DPA. Note If the status of the VolumeSnapshotBackup CR becomes Failed , refer to the Velero logs for troubleshooting. You can restore a volume snapshot by performing the following steps: Delete the application namespace and the volumeSnapshotContent that was created by the Velero CSI plugin. Create a Restore CR and set restorePVs to true . Example Restore CR apiVersion: velero.io/v1 kind: Restore metadata: name: <restore_name> namespace: <protected_ns> spec: backupName: <previous_backup_name> restorePVs: true Wait up to 10 minutes and check whether the VolumeSnapshotRestore CR status is Completed by entering the following command: USD oc get vsr -n <app_ns> USD oc get vsr <vsr_name> -n <app_ns> -o jsonpath="{.status.phase}" Check whether your application data and resources have been restored. Note If the status of the VolumeSnapshotRestore CR becomes 'Failed', refer to the Velero logs for troubleshooting. Additional resources Installing Operators on clusters for administrators Installing Operators in namespaces for non-administrators 4.4.1.5. Creating backup hooks You create backup hooks to run commands in a container in a pod by editing the Backup custom resource (CR). Pre hooks run before the pod is backed up. Post hooks run after the backup. Procedure Add a hook to the spec.hooks block of the Backup CR, as in the following example: apiVersion: velero.io/v1 kind: Backup metadata: name: <backup> namespace: openshift-adp spec: hooks: resources: - name: <hook_name> includedNamespaces: - <namespace> 1 excludedNamespaces: 2 - <namespace> includedResources: [] - pods 3 excludedResources: [] 4 labelSelector: 5 matchLabels: app: velero component: server pre: 6 - exec: container: <container> 7 command: - /bin/uname 8 - -a onError: Fail 9 timeout: 30s 10 post: 11 ... 1 Optional: You can specify namespaces to which the hook applies. If this value is not specified, the hook applies to all namespaces. 2 Optional: You can specify namespaces to which the hook does not apply. 3 Currently, pods are the only supported resource that hooks can apply to. 4 Optional: You can specify resources to which the hook does not apply. 5 Optional: This hook only applies to objects matching the label. If this value is not specified, the hook applies to all namespaces. 6 Array of hooks to run before the backup. 7 Optional: If the container is not specified, the command runs in the first container in the pod. 8 This is the entrypoint for the init container being added. 9 Allowed values for error handling are Fail and Continue . The default is Fail . 10 Optional: How long to wait for the commands to run. The default is 30s . 11 This block defines an array of hooks to run after the backup, with the same parameters as the pre-backup hooks. 4.4.1.6. Scheduling backups You schedule backups by creating a Schedule custom resource (CR) instead of a Backup CR. Warning Leave enough time in your backup schedule for a backup to finish before another backup is created. For example, if a backup of a namespace typically takes 10 minutes, do not schedule backups more frequently than every 15 minutes. Prerequisites You must install the OpenShift API for Data Protection (OADP) Operator. The DataProtectionApplication CR must be in a Ready state. Procedure Retrieve the backupStorageLocations CRs: USD oc get backupStorageLocations Example output NAME PHASE LAST VALIDATED AGE DEFAULT velero-sample-1 Available 11s 31m Create a Schedule CR, as in the following example: USD cat << EOF | oc apply -f - apiVersion: velero.io/v1 kind: Schedule metadata: name: <schedule> namespace: openshift-adp spec: schedule: 0 7 * * * 1 template: hooks: {} includedNamespaces: - <namespace> 2 storageLocation: <velero-sample-1> 3 defaultVolumesToRestic: true 4 ttl: 720h0m0s EOF 1 cron expression to schedule the backup, for example, 0 7 * * * to perform a backup every day at 7:00. 2 Array of namespaces to back up. 3 Name of the backupStorageLocations CR. 4 Optional: Add the defaultVolumesToRestic: true key-value pair if you are backing up volumes with Restic. Verify that the status of the Schedule CR is Completed after the scheduled backup runs: USD oc get schedule -n openshift-adp <schedule> -o jsonpath='{.status.phase}' 4.4.1.7. Deleting backups You can remove backup files by deleting the Backup custom resource (CR). Warning After you delete the Backup CR and the associated object storage data, you cannot recover the deleted data. Prerequisites You created a Backup CR. You know the name of the Backup CR and the namespace that contains it. You downloaded the Velero CLI tool. You can access the Velero binary in your cluster. Procedure Choose one of the following actions to delete the Backup CR: To delete the Backup CR and keep the associated object storage data, issue the following command: USD oc delete backup <backup_CR_name> -n <velero_namespace> To delete the Backup CR and delete the associated object storage data, issue the following command: USD velero backup delete <backup_CR_name> -n <velero_namespace> Where: <backup_CR_name> Specifies the name of the Backup custom resource. <velero_namespace> Specifies the namespace that contains the Backup custom resource. Additional resources Downloading the Velero CLI tool 4.4.2. Restoring applications You restore application backups by creating a Restore custom resources (CRs) . You can create restore hooks to run commands in init containers, before the application container starts, or in the application container itself. 4.4.2.1. Creating a Restore CR You restore a Backup custom resource (CR) by creating a Restore CR. Prerequisites You must install the OpenShift API for Data Protection (OADP) Operator. The DataProtectionApplication CR must be in a Ready state. You must have a Velero Backup CR. Adjust the requested size so the persistent volume (PV) capacity matches the requested size at backup time. Procedure Create a Restore CR, as in the following example: apiVersion: velero.io/v1 kind: Restore metadata: name: <restore> namespace: openshift-adp spec: backupName: <backup> 1 includedResources: [] 2 excludedResources: - nodes - events - events.events.k8s.io - backups.velero.io - restores.velero.io - resticrepositories.velero.io restorePVs: true 1 Name of the Backup CR. 2 Optional. Specify an array of resources to include in the restore process. Resources might be shortcuts (for example, 'po' for 'pods') or fully-qualified. If unspecified, all resources are included. Verify that the status of the Restore CR is Completed by entering the following command: USD oc get restore -n openshift-adp <restore> -o jsonpath='{.status.phase}' Verify that the backup resources have been restored by entering the following command: USD oc get all -n <namespace> 1 1 Namespace that you backed up. If you use Restic to restore DeploymentConfig objects or if you use post-restore hooks, run the dc-restic-post-restore.sh cleanup script by entering the following command: USD bash dc-restic-post-restore.sh <restore-name> Note In the course of the restore process, the OADP Velero plug-ins scale down the DeploymentConfig objects and restore the pods as standalone pods to prevent the cluster from deleting the restored DeploymentConfig pods immediately on restore and to allow Restic and post-restore hooks to complete their actions on the restored pods. The cleanup script removes these disconnected pods and scale any DeploymentConfig objects back up to the appropriate number of replicas. Example 4.1. dc-restic-post-restore.sh cleanup script #!/bin/bash set -e # if sha256sum exists, use it to check the integrity of the file if command -v sha256sum >/dev/null 2>&1; then CHECKSUM_CMD="sha256sum" else CHECKSUM_CMD="shasum -a 256" fi label_name () { if [ "USD{#1}" -le "63" ]; then echo USD1 return fi sha=USD(echo -n USD1|USDCHECKSUM_CMD) echo "USD{1:0:57}USD{sha:0:6}" } OADP_NAMESPACE=USD{OADP_NAMESPACE:=openshift-adp} if [[ USD# -ne 1 ]]; then echo "usage: USD{BASH_SOURCE} restore-name" exit 1 fi echo using OADP Namespace USDOADP_NAMESPACE echo restore: USD1 label=USD(label_name USD1) echo label: USDlabel echo Deleting disconnected restore pods oc delete pods -l oadp.openshift.io/disconnected-from-dc=USDlabel for dc in USD(oc get dc --all-namespaces -l oadp.openshift.io/replicas-modified=USDlabel -o jsonpath='{range .items[*]}{.metadata.namespace}{","}{.metadata.name}{","}{.metadata.annotations.oadp\.openshift\.io/original-replicas}{","}{.metadata.annotations.oadp\.openshift\.io/original-paused}{"\n"}') do IFS=',' read -ra dc_arr <<< "USDdc" if [ USD{#dc_arr[0]} -gt 0 ]; then echo Found deployment USD{dc_arr[0]}/USD{dc_arr[1]}, setting replicas: USD{dc_arr[2]}, paused: USD{dc_arr[3]} cat <<EOF | oc patch dc -n USD{dc_arr[0]} USD{dc_arr[1]} --patch-file /dev/stdin spec: replicas: USD{dc_arr[2]} paused: USD{dc_arr[3]} EOF fi done 4.4.2.2. Creating restore hooks You create restore hooks to run commands in a container in a pod while restoring your application by editing the Restore custom resource (CR). You can create two types of restore hooks: An init hook adds an init container to a pod to perform setup tasks before the application container starts. If you restore a Restic backup, the restic-wait init container is added before the restore hook init container. An exec hook runs commands or scripts in a container of a restored pod. Procedure Add a hook to the spec.hooks block of the Restore CR, as in the following example: apiVersion: velero.io/v1 kind: Restore metadata: name: <restore> namespace: openshift-adp spec: hooks: resources: - name: <hook_name> includedNamespaces: - <namespace> 1 excludedNamespaces: - <namespace> includedResources: - pods 2 excludedResources: [] labelSelector: 3 matchLabels: app: velero component: server postHooks: - init: initContainers: - name: restore-hook-init image: alpine:latest volumeMounts: - mountPath: /restores/pvc1-vm name: pvc1-vm command: - /bin/ash - -c timeout: 4 - exec: container: <container> 5 command: - /bin/bash 6 - -c - "psql < /backup/backup.sql" waitTimeout: 5m 7 execTimeout: 1m 8 onError: Continue 9 1 Optional: Array of namespaces to which the hook applies. If this value is not specified, the hook applies to all namespaces. 2 Currently, pods are the only supported resource that hooks can apply to. 3 Optional: This hook only applies to objects matching the label selector. 4 Optional: Timeout specifies the maximum amount of time Velero waits for initContainers to complete. 5 Optional: If the container is not specified, the command runs in the first container in the pod. 6 This is the entrypoint for the init container being added. 7 Optional: How long to wait for a container to become ready. This should be long enough for the container to start and for any preceding hooks in the same container to complete. If not set, the restore process waits indefinitely. 8 Optional: How long to wait for the commands to run. The default is 30s . 9 Allowed values for error handling are Fail and Continue : Continue : Only command failures are logged. Fail : No more restore hooks run in any container in any pod. The status of the Restore CR will be PartiallyFailed . 4.5. Troubleshooting You can debug Velero custom resources (CRs) by using the OpenShift CLI tool or the Velero CLI tool . The Velero CLI tool provides more detailed logs and information. You can check installation issues , backup and restore CR issues , and Restic issues . You can collect logs, CR information, and Prometheus metric data by using the must-gather tool . You can obtain the Velero CLI tool by: Downloading the Velero CLI tool Accessing the Velero binary in the Velero deployment in the cluster 4.5.1. Downloading the Velero CLI tool You can download and install the Velero CLI tool by following the instructions on the Velero documentation page . The page includes instructions for: macOS by using Homebrew GitHub Windows by using Chocolatey Prerequisites You have access to a Kubernetes cluster, v1.16 or later, with DNS and container networking enabled. You have installed kubectl locally. Procedure Open a browser and navigate to "Install the CLI" on the Verleo website . Follow the appropriate procedure for macOS, GitHub, or Windows. Download the Velero version appropriate for your version of OADP and OpenShift Container Platform according to the table that follows: Table 4.2.

Accessing the Velero binary in the Velero deployment in the cluster You can use a shell command to access the Velero binary in the Velero deployment in the cluster. Prerequisites Your DataProtectionApplication custom resource has a status of Reconcile complete . Procedure Enter the following command to set the needed alias: USD alias velero='oc -n openshift-adp exec deployment/velero -c velero -it -- ./velero' 4.5.3. Debugging Velero resources with the OpenShift CLI tool You can debug a failed backup or restore by checking Velero custom resources (CRs) and the Velero pod log with the OpenShift CLI tool. Velero CRs Use the oc describe command to retrieve a summary of warnings and errors associated with a Backup or Restore CR: USD oc describe <velero_cr> <cr_name> Velero pod logs Use the oc logs command to retrieve the Velero pod logs: USD oc logs pod/<velero> Velero pod debug logs You can specify the Velero log level in the DataProtectionApplication resource as shown in the following example. Note This option is available starting from OADP 1.0.3. apiVersion: oadp.openshift.io/v1alpha1 kind: DataProtectionApplication metadata: name: velero-sample spec: configuration: velero: logLevel: warning The following logLevel values are available: trace debug info warning error fatal panic It is recommended to use debug for most logs. 4.5.4. Debugging Velero resources with the Velero CLI tool You can debug Backup and Restore custom resources (CRs) and retrieve logs with the Velero CLI tool. The Velero CLI tool provides more detailed information than the OpenShift CLI tool.

Issues with Velero and admission webhooks Velero has limited abilities to resolve admission webhook issues during a restore. If you have workloads with admission webhooks, you might need to use an additional Velero plugin or make changes to how you restore the workload. Typically, workloads with admission webhooks require you to create a resource of a specific kind first. This is especially true if your workload has child resources because admission webhooks typically block child resources. For example, creating or restoring a top-level object such as service.serving.knative.dev typically creates child resources automatically. If you do this first, you will not need to use Velero to create and restore these resources. This avoids the problem of child resources being blocked by an admission webhook that Velero might use. 4.5.5.1. Restoring workarounds for Velero backups that use admission webhooks This section describes the additional steps required to restore resources for several types of Velero backups that use admission webhooks. 4.5.5.1.1. Restoring Knative resources You might encounter problems using Velero to back up Knative resources that use admission webhooks. You can avoid such problems by restoring the top level Service resource first whenever you back up and restore Knative resources that use admission webhooks. Procedure Restore the top level service.serving.knavtive.dev Service resource: USD velero restore <restore_name> \ --from-backup=<backup_name> --include-resources \ service.serving.knavtive.dev 4.5.5.1.2. Restoring IBM AppConnect resources If you experience issues when you use Velero to a restore an IBM AppConnect resource that has an admission webhook, you can run the checks in this procedure. Procedure Check if you have any mutating admission plugins of kind: MutatingWebhookConfiguration in the cluster: USD oc get mutatingwebhookconfigurations Examine the YAML file of each kind: MutatingWebhookConfiguration to ensure that none of its rules block creation of the objects that are experiencing issues. For more information, see the official Kuberbetes documentation . Check that any spec.version in type: Configuration.appconnect.ibm.com/v1beta1 used at backup time is supported by the installed Operator. Additional resources Admission plugins Webhook admission plugins Types of webhook admission plugins 4.5.6. Installation issues You might encounter issues caused by using invalid directories or incorrect credentials when you install the Data Protection Application. 4.5.6.1. Backup storage contains invalid directories The Velero pod log displays the error message, Backup storage contains invalid top-level directories . Cause The object storage contains top-level directories that are not Velero directories. Solution If the object storage is not dedicated to Velero, you must specify a prefix for the bucket by setting the spec.backupLocations.velero.objectStorage.prefix parameter in the DataProtectionApplication manifest. 4.5.6.2. Incorrect AWS credentials The oadp-aws-registry pod log displays the error message, InvalidAccessKeyId: The AWS Access Key Id you provided does not exist in our records. The Velero pod log displays the error message, NoCredentialProviders: no valid providers in chain . Cause The credentials-velero file used to create the Secret object is incorrectly formatted. Solution Ensure that the credentials-velero file is correctly formatted, as in the following example: Example credentials-velero file 1 AWS default profile. 2 Do not enclose the values with quotation marks ( " , ' ). 4.5.7. Backup and Restore CR issues You might encounter these common issues with Backup and Restore custom resources (CRs). 4.5.7.1. Backup CR cannot retrieve volume The Backup CR displays the error message, InvalidVolume.NotFound: The volume 'vol-xxxx' does not exist . Cause The persistent volume (PV) and the snapshot locations are in different regions. Solution Edit the value of the spec.snapshotLocations.velero.config.region key in the DataProtectionApplication manifest so that the snapshot location is in the same region as the PV. Create a new Backup CR. 4.5.7.2. Backup CR status remains in progress The status of a Backup CR remains in the InProgress phase and does not complete. Cause If a backup is interrupted, it cannot be resumed. Solution Retrieve the details of the Backup CR: USD oc -n {namespace} exec deployment/velero -c velero -- ./velero \ backup describe <backup> Delete the Backup CR: USD oc delete backup <backup> -n openshift-adp You do not need to clean up the backup location because a Backup CR in progress has not uploaded files to object storage. Create a new Backup CR. 4.5.7.3. Backup CR status remains in PartiallyFailed The status of a Backup CR without Restic in use remains in the PartiallyFailed phase and does not complete. A snapshot of the affiliated PVC is not created. Cause If the backup is created based on the CSI snapshot class, but the label is missing, CSI snapshot plugin fails to create a snapshot. As a result, the Velero pod logs an error similar to the following: + time="2023-02-17T16:33:13Z" level=error msg="Error backing up item" backup=openshift-adp/user1-backup-check5 error="error executing custom action (groupResource=persistentvolumeclaims, namespace=busy1, name=pvc1-user1): rpc error: code = Unknown desc = failed to get volumesnapshotclass for storageclass ocs-storagecluster-ceph-rbd: failed to get volumesnapshotclass for provisioner openshift-storage.rbd.csi.ceph.com, ensure that the desired volumesnapshot class has the velero.io/csi-volumesnapshot-class label" logSource="/remote-source/velero/app/pkg/backup/backup.go:417" name=busybox-79799557b5-vprq Solution Delete the Backup CR: USD oc delete backup <backup> -n openshift-adp If required, clean up the stored data on the BackupStorageLocation to free up space. Apply label velero.io/csi-volumesnapshot-class=true to the VolumeSnapshotClass object: USD oc label volumesnapshotclass/<snapclass_name> velero.io/csi-volumesnapshot-class=true Create a new Backup CR. 4.5.8. Restic issues You might encounter these issues when you back up applications with Restic. 4.5.8.1. Restic permission error for NFS data volumes with root_squash enabled The Restic pod log displays the error message: controller=pod-volume-backup error="fork/exec/usr/bin/restic: permission denied" . Cause If your NFS data volumes have root_squash enabled, Restic maps to nfsnobody and does not have permission to create backups. Solution You can resolve this issue by creating a supplemental group for Restic and adding the group ID to the DataProtectionApplication manifest: Create a supplemental group for Restic on the NFS data volume. Set the setgid bit on the NFS directories so that group ownership is inherited. Add the spec.configuration.restic.supplementalGroups parameter and the group ID to the DataProtectionApplication manifest, as in the following example: spec: configuration: restic: enable: true supplementalGroups: - <group_id> 1 1 Specify the supplemental group ID. Wait for the Restic pods to restart so that the changes are applied. 4.5.8.2. Restic Backup CR cannot be recreated after bucket is emptied If you create a Restic Backup CR for a namespace, empty the object storage bucket, and then recreate the Backup CR for the same namespace, the recreated Backup CR fails. The velero pod log displays the following error message: stderr=Fatal: unable to open config file: Stat: The specified key does not exist.\nIs there a repository at the following location? . Cause Velero does not recreate or update the Restic repository from the ResticRepository manifest if the Restic directories are deleted from object storage. See Velero issue 4421 for more information. Solution Remove the related Restic repository from the namespace by running the following command: USD oc delete resticrepository openshift-adp <name_of_the_restic_repository> In the following error log, mysql-persistent is the problematic Restic repository. The name of the repository appears in italics for clarity. time="2021-12-29T18:29:14Z" level=info msg="1 errors encountered backup up item" backup=velero/backup65 logSource="pkg/backup/backup.go:431" name=mysql-7d99fc949-qbkds time="2021-12-29T18:29:14Z" level=error msg="Error backing up item" backup=velero/backup65 error="pod volume backup failed: error running restic backup, stderr=Fatal: unable to open config file: Stat: The specified key does not exist.\nIs there a repository at the following location?\ns3:http://minio-minio.apps.mayap-oadp- veleo-1234.qe.devcluster.openshift.com/mayapvelerooadp2/velero1/ restic/ mysql-persistent \n: exit status 1" error.file="/remote-source/ src/github.com/vmware-tanzu/velero/pkg/restic/backupper.go:184" error.function="github.com/vmware-tanzu/velero/ pkg/restic.(*backupper).BackupPodVolumes" logSource="pkg/backup/backup.go:435" name=mysql-7d99fc949-qbkds 4.5.9. Using the must-gather tool You can collect logs, metrics, and information about OADP custom resources by using the must-gather tool. The must-gather data must be attached to all customer cases. Prerequisites You must be logged in to the OpenShift Container Platform cluster as a user with the cluster-admin role. You must have the OpenShift CLI ( oc ) installed.

Advanced OADP features and functionalities This document provides information on advanced features and functionalities of OpenShift API for Data Protection (OADP). 4.7.1. Working with different Kubernetes API versions on the same cluster 4.7.1.1. Listing the Kubernetes API group versions on a cluster A source cluster might offer multiple versions of an API, where one of these versions is the preferred API version. For example, a source cluster with an API named Example might be available in the example.com/v1 and example.com/v1beta2 API groups. If you use Velero to back up and restore such a source cluster, Velero backs up only the version of that resource that uses the preferred version of its Kubernetes API. To return to the above example, if example.com/v1 is the preferred API, then Velero only backs up the version of a resource that uses example.com/v1 . Moreover, the target cluster needs to have example.com/v1 registered in its set of available API resources in order for Velero to restore the resource on the target cluster. Therefore, you need to generate a list of the Kubernetes API group versions on your target cluster to be sure the prefered API version is registered in its set of available API resources. Procedure Enter the following command: USD oc api-resources 4.7.1.2. About Enable API Group Versions By default, Velero only backs up resources that use the preferred version of the Kubernetes API. However, Velero also includes a feature, Enable API Group Versions , that overcomes this limitation. When enabled on the source cluster, this feature causes Velero to back up all Kubernetes API group versions that are supported on the cluster, not only the preferred one. After the versions are stored in the backup .tar file, they are available to be restored on the destination cluster. For example, a source cluster with an API named Example might be available in the example.com/v1 and example.com/v1beta2 API groups, with example.com/v1 being the preferred API. Without the Enable API Group Versions feature enabled, Velero backs up only the preferred API group version for Example , which is example.com/v1 . With the feature enabled, Velero also backs up example.com/v1beta2 . When the Enable API Group Versions feature is enabled on the destination cluster, Velero selects the version to restore on the basis of the order of priority of API group versions. Note Enable API Group Versions is still in beta. Velero uses the following algorithm to assign priorities to API versions, with 1 as the top priority: Preferred version of the destination cluster Preferred version of the source_ cluster Common non-preferred supported version with the highest Kubernetes version priority Additional resources Enable API Group Versions Feature 4.7.1.3. Using Enable API Group Versions You can use Velero's Enable API Group Versions feature to back up all Kubernetes API group versions that are supported on a cluster, not only the preferred one. Note Enable API Group Versions is still in beta. Procedure Configure the EnableAPIGroupVersions feature flag: apiVersion: oadp.openshift.io/vialpha1 kind: DataProtectionApplication ... spec: configuration: velero: featureFlags: - EnableAPIGroupVersions Additional resources Enable API Group Versions Feature
