Chapter 12. Restoring Satellite Server or Capsule Server from a backup You can restore Satellite Server or Capsule Server from the backup data that you create as part of Chapter 11, Backing up Satellite Server and Capsule Server . This process outlines how to restore the backup on the same server that generated the backup, and all data covered by the backup is deleted on the target system. If the original system is unavailable, provision a system with the same configuration settings and host name. 12.1. Restoring from a full backup Use this procedure to restore Red Hat Satellite or Capsule Server from a full backup. When the restore process completes, all processes are online, and all databases and system configuration revert to the state at the time of the backup. Prerequisites Ensure that you are restoring to the correct instance. The Red Hat Satellite instance must have the same host name, configuration, and be the same minor version (X.Y) as the original system. Ensure that you have an existing target directory. The target directory is read from the configuration files contained within the archive. Ensure that you have enough space to store this data on the base system of Satellite Server or Capsule Server as well as enough space after the restoration to contain all the data in the /etc/ and /var/ directories contained within the backup. To check the space used by a directory, enter the following command: To check for free space, enter the following command: Add the --total option to get a total of the results from more than one directory. Ensure that all SELinux contexts are correct. Enter the following command to restore the correct SELinux contexts: Procedure Choose the appropriate method to install Satellite or Capsule: To install Satellite Server from a connected network, follow the procedures in Installing Satellite Server in a connected network environment . To install Satellite Server from a disconnected network, follow the procedures in Installing Satellite Server in a disconnected network environment . To install a Capsule Server, follow the procedures in Installing Capsule Server . Copy the backup data to Satellite Server's local file system. Use /var/ or /var/tmp/ . Run the restoration script. Where backup_directory is the time-stamped directory or subdirectory containing the backed-up data. The restore process can take a long time to complete, because of the amount of data to copy. Additional resources For troubleshooting, you can check /var/log/foreman/production.log and /var/log/messages . 12.2. Restoring from incremental backups Use this procedure to restore Satellite or Capsule Server from incremental backups. If you have multiple branches of incremental backups, select your full backup and each incremental backup for the branch you want to restore, in chronological order. When the restore process completes, all processes are online, and all databases and system configuration revert to the state at the time of the backup. Procedure Restore the last full backup using the instructions in Section 12.1, "Restoring from a full backup" . Remove the full backup data from Satellite Server's local file system, for example, /var/ or /var/tmp/ . Copy the incremental backup data to Satellite Server's local file system, for example, /var/ or /var/tmp/ . Restore the incremental backups in the same sequence that they are made: Additional resources For troubleshooting, you can check /var/log/foreman/production.log and /var/log/messages . 12.3. Backup and restore Capsule Server using a virtual machine snapshot If your Capsule Server is a virtual machine, you can restore it from a snapshot. Creating weekly snapshots to restore from is recommended. In the event of failure, you can install, or configure a new Capsule Server, and then synchronize the database content from Satellite Server. If required, deploy a new Capsule Server, ensuring the host name is the same as before, and then install the Capsule certificates. You may still have them on Satellite Server, the package name ends in -certs.tar, alternately create new ones. Follow the procedures in Installing Capsule Server until you can confirm, in the Satellite web UI, that Capsule Server is connected to Satellite Server. Then use the procedure Section 12.3.1, "Synchronizing content from Satellite Server to Capsule Servers" to synchronize from Satellite. 12.3.1. Synchronizing content from Satellite Server to Capsule Servers Use this procedure to synchronize content from your Satellite Server to your Capsule Server. Prerequisites Ensure that you either select the relevant organization and location context of your Capsule Server or choose Any Organization and Any Location . Procedure In the Satellite web UI, navigate to Infrastructure > Capsules . Select your Capsule Server. On the Overview tab, click Synchronize . Select Optimized Sync to synchronize content from your Satellite Server to your Capsule Server that bypasses unnecessary steps to speed up performance. Select Complete Sync to perform a complete sync from your Satellite Server to your Capsule Server that synchronizes content even if the metadata has not changed.
