Introduction to Storage Bridge

Congratulations on your purchase of Tiger Technology’s Storage Bridge. Storage Bridge leverages
your Milestone XProtect VMS with flexible disaster recovery capabilities and/or seamlessextension of the recording storage and archive's capacity to an external storage tier. By enabling acloud target, a network share or any local volume to seamlessly integrate into your XProtect storage
infrastructure, Storage Bridge allows for increased maximum recording and archive retention
limits and further ensures your XProtect VMS against data loss.

How It Works
As soon as you install Storage Bridge on the recording server(s) and the XProtect Management
client, you are ready to enable a cloud target, network share or another local volume as an extension
and/or disaster recovery storage of a selected recording storage/archive. For the purpose, you
should simply provide the credentials for access to the selected extension/disaster recovery
storage. As long as Storage Bridge is not paused it immediately begins processing data.
You can enable just extension, just disaster recovery or both on a recording storage/archive. Whenboth are enabled for one and the same recording storage/archive, the same cloud storage provider,network share or local volume is used. You can enable storage extension/disaster recovery on a
cloud target for a given recording storage and storage extension/disaster recovery on a network
share for the same recording server’s archive storage, for example. The two mechanisms are notinterchangeable - enabling disaster recovery does not free space on your recording storage/archiveand data moved to the extension cannot be used for disaster recovery as it does not include system
information, about your recording storage/archive or recording server.

Disaster Recovery
When you enable disaster recovery, Storage Bridge copies all data and metadata from the recording
storage/archive to the specified cloud, network share or local volume, starting with the oldest files.
The time for complete backup depends on the network characteristics and connection speed to thedisaster recovery storage target. You can keep track of the data backup progress in the Storage
Bridge interface.
Storage Bridge disaster recovery is meant to provide a safety net in case of an unforeseen failure ofa recording storage/archive or the recording server itself. Thus, it keeps backed up data on thedisaster recovery storage for as long as you have specified in XProtect. Should a recording storage/archive reach its retention limit, XProtect will start deleting data and Storage Bridge thenautomatically deletes the counterpart from the disaster recovery storage, freeing space for newdata.
In case of a failure of a recording server or its recording storage/archive, you can immediately begin
recovering all backed up data and make it usable through XProtect VMS again.

8How It Works

Storage Extension
When you extend a recording storage/archive, you simply increase its capacity with the free spaceon the cloud target, network share, or local volume you have added as an extension. You can expand
the capacity of a recording server’s storage with a nearline extension, from which data is retrieved
as soon as the connection speed allows, or an offline extension (currently, Storage Bridge supports
Amazon Glacier, Microsoft Archive and Google Archive), from which data is not retrieved
immediately, but must first be rehydrated to an intermediate tier.
Space on the recording storage/archive is freed by moving recordings to the enabled extension. To
determine when to move recordings from the recording storage/archive to the nearline extension,
Storage Bridge utilizes either the “by size” or the “by age” criteria you configure. With the “by age”
method, data is moved to the nearline extension when it has not been accessed for a specified timeinterval. With the “by size” criteria, Storage Bridge begins moving data when the used space on therecording storage/archive reaches a specified threshold, starting with the least recently accessed
files. To determine when a recording should be moved from the nearline extension to the offline
extension, if enabled, Storage Bridge utilizes the “by age” criteria i.e. moves files, which have notbeen accessed for a specified time period.
Once a file is moved to the storage extension, Storage Bridge replaces it with a stub file. Stub files
look and act exactly like the actual files they replace, but have almost no size and consume almost
no capacity on your local storage/archive. Stub files pointing to actual files on the nearline
extension allow immediate and seamless retrieval when playing back and reviewing timeline video.
Storage Bridge also allows you to manually move data between the local recording storage/archiveand the nearline and offline extensions.
As with disaster recovery, recordings are kept on the nearline/offline extension for as long as theretention limit of the extended recording storage/archive requires. Once the retention limit for a
specific recording is reached, both the stub file and its counterpart on the extension areautomatically deleted.

9Introduction to Storage Bridge

XProtect Smart Client Integration

To facilitate the work of XProtect Smart Client users, the administrator of your surveillance system
can enable or disable the integration of Storage Bridge. When enabled, each XProtect Smart Clientcomputer running the Storage Bridge plug-in sees an additional timeline visually displaying theoriginal recording storage/archive, the nearline extension, or the offline extension as enabled by
Storage Bridge.
Additionally, when the XProtect Smart Client integration is enabled, users can restore recordings
from the nearline or offline extension to the recording storage/archive automatically (whenreviewing the recording, for example) or manually, for a selected timeframe.

Storage Bridge Licensing
In order to benefit from Storage Bridge, you need to activate it on each recording server. For
activation Storage Bridge makes use of a software as a service (SaaS). For more information, refer
to “Activate Storage Bridge” on page 24. The license holds information about the maximum
number of cameras attached to a recording server.
Note: When provided for evaluation purposes, a license may be valid only for a specific amountof time.
10

System Requirements

You can keep track of the activation status of a recording server, following the steps on page 25.

System Requirements
To benefit from Storage Bridge in your XProtect VMS, you must install the Storage Bridge plug-inon the XProtect Management Client and Storage Bridge itself on each recording server whose
storage you want to extend or back up. Additionally, to allow XProtect Smart Client integration, youneed to install the Storage Bridge XProtect Smart Client plug-in on each computer you want tointegrate.

Storage Bridge
To install Storage Bridge on a recording server whose storage you want to extend and/or back up,
it must meet the following minimum requirements:• PC with 64-bit (x64) processor.
Note: Storage Bridge actively uses the APIs provided by the target provider. These APIs may
take significant amount of CPU depending on connection and the amount of data moved. Please,refer to the minimum CPU requirements of your target provider.

• 64-bit Microsoft Windows® 7/Server 2008 R2/Windows® 8/Server 2012/Server 2012 R2/Windows® 10/Server 2016/Server 2019.
Important: Microsoft Windows® 7/Server 2008 R2 computers must run at least Service Pack
1 and have the KB976932 and the KB3033929 security updates installed.

• 4 GB of physical RAM at least.
• 30 MB of available hard-disk space for Storage Bridge installation.
Note: Storage Bridge keeps track of the files it manages in a database, stored in the productinstallation folder. The size of the database grows proportionally to the number of files
managed. For example, if Storage Bridge manages 1 000 000 files, the size of the database isapproximately 100MB. Unless there’s enough free space for the database, Storage Bridge isunable to operate.

• The following TCP ports must not be blocked by the firewall on the recording server or thecomputer managing the inbound and outbound traffic on your network:• (for communication with object storage target over http connection) 80 - outbound rule only
• (for SaaS activation and/or communication with object storage target over https) 443 outbound rule only
• (for communication with SMB network share target) 445 - outbound rule only
• 8536 - inbound and outbound rules• 8537 - inbound and outbound rules

Storage Requirements
Recording Storage/Archive Requirements
Currently, Storage Bridge supports only recording storage/archive, which is mounted on therecording server as a local NTFS volume with Read & Write permissions and on which the System
account is granted Full Control.

Extension/Disaster Recovery Storage Requirements
Currently, Storage Bridge supports the following storage types for extension and/or disasterrecovery:
Note: Refer to “Extension/Disaster Recovery Storage Prerequisites” on page 13 for specificrequirements about each storage type.

• Amazon S3 object storage• Microsoft Azure blob storage• Backblaze B2 cloud storage• Google cloud storage• IBM Cloud object storage• Wasabi Hot Cloud Storage• Hitachi Content Platform (HCP)• Seagate CORTX
12

Storage Requirements• S3-compatible object storage (using protocol signature version 2)• SMB/CIFS network share• another volume, mounted on the recording server as a local volume with Read & Writepermissions

Extension/Disaster Recovery Storage Prerequisites
Amazon S3 Object Storage• create a separate empty bucket for each recording storage/archive you want to extend and/orback up on Amazon S3 object storage• provide IAM user credentials to be used by Storage Bridge
Important: Never provide your AWS account root user credentials. For best practices on
securing your AWS resources, refer to the following recommendations for the AWS Identity andAccess Management (IAM) service:https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html
Tip:

Storage Bridge does not require that the IAM user has permissions to list other buckets oreven to delete the bucket, which will be paired with the recording storage/archive. You can ensurethat Storage Bridge operates normally, if you grant the IAM user full permissions over objects inthe bucket. Still, if the security policies of your organization are more restrictive, you can use thefollowing bucket policy as a sample for granting the minimum required permissions for a bucket"bucket-name" to user “bridge_user”:{"Version": "2012-10-17","Id": "S3AllActionsOnTigerBucket","Statement": [{"Sid": "AllowAllActionOnS3ToTigerUsers","Effect": "Allow","Principal": {"AWS": "arn:aws:iam::your_aws_subscription:user/bridge_user"},"Action": ["s3:GetAccelerateConfiguration","s3:GetBucketLocation","s3:GetBucketVersioning","s3:ListBucket","s3:ListBucketVersions","s3:ListBucketMultipartUploads","s3:PutLifeCycleConfiguration"],"Resource": "arn:aws:s3:::bucket-name"},{"Effect": "Allow","Principal": {13

The time for full backup depends on the network characteristics and connection speed to thedisaster recovery storage. You can keep track of the progress of data backup following the steps in“Monitor Data Backup” on page 35.
Storage Bridge disaster recovery is meant to provide a safety net in case of an unforeseen failure ofa recording server’s recording storage/archive or the recording server itself. In case of a failure, you
can immediately begin recovering all backed up data by following the steps in “Recover Backed Up
Data” on page 38.

Enable Disaster Recovery
To enable disaster recovery, you should simply provide the credentials for access to the cloudstorage, network share or local volume, which will be used for backing data up. If a nearline/offline
extension is already enabled for the selected recording storage or archive, the same cloud storage,
network share or local volume is also used for disaster recovery and there is no need to provide thecredentials for access to the disaster recovery storage.
Important: Storage Bridge does not allow you to use the same bucket/container (on cloudstorage) or folder (on network share or local volume) as a disaster recovery location of more than
one recording storage/archive.

To change the type of disaster recovery storage or the credentials for access to it, you need to firstdisable disaster recovery, following the steps in “Disable Disaster Recovery” on page 30 and thenconfigure it again. Keep in mind that if you want to change the type of disaster recovery storage or
the credentials for access to it, and a nearline/offline extension is also enabled, you must firstdisable the extension(s), following the steps in “Disable a Storage Extension” on page 54.

in case of a recording storage/archive failure. Additionally, once you disable disaster recovery, dataon it is no longer automatically deleted once the retention limit set for the respective recording
storage/archive is reached.
Important: If the recording storage/archive whose disaster recovery you disable also has
nearline/offline extension enabled, Storage Bridge stops backing up data, but the storage
extension mechanism continues operation. You are also still able to manually move data to andfrom the extension, following the steps in “Manually Manage Data” on page 65.

If you want to disable disaster recovery in order to change the credentials for access to the disasterrecovery storage, make sure the new credentials provide access to data already backed up.
Otherwise it may remain unavailable for recovery in your XProtect VMS. If you want to disable
disaster recovery in order to change the type of disaster recovery storage, it is advisable to firstmigrate all data from your current disaster recovery storage.

Recover Backed Up Data
The Disaster Recovery Wizard of Storage Bridge guides you in recovering a failed recording
storage, archive or recording server. The wizard becomes available only when a disaster recovery
condition is present. That is why it is important to carefully monitor your recording server(s) andstorages, before attempting to recover them. Detailed steps about diagnosing a disaster recovery
condition are provided below.
To speed up the disaster recovery and reduce downtime, you can prepare your recording server(s)system and storage, following the disaster recovery prerequisites provided below. It is of great
importance to adhere to the disaster recovery precautions, provided before the recovery
procedures in order to prevent irrecoverable data and metadata.

Recover Recording Storage/Archive
Follow these procedures to recover backed up data from a failed recording storage or archive:• diagnose the failed recording storage/archive• prepare the storage for recovery of backed up data
• recover data and metadata with the Disaster Recovery Wizard

38

Recover Backed Up Data

Diagnose a Failed Recording Storage/Archive
You can diagnose a recording storage/archive failure in the Disaster Recovery page of the XProtect
Management Client plug-in:• a recording server whose recording storage and/or archive has failed is displayed in the page witha red blinking icon
• a failed recording storage or archive is displayed in the list with a warning sign
• the Disaster Recovery Wizard button is available in the recording servers’ pane

Storage Disaster Recovery Precautions and Prerequisites
Once you have ensured that a recording storage and/or an archive has indeed failed, you must takethe following precautions in order to ensure that data can be recovered:
1. Do not attempt to recover or mount on the recording server any volume with the same drive

letter as the failed one(s), on which a recording storage/archive has been stored.
2. Once you start the disaster recovery procedure, do not restart the recording server until you

complete the procedure in the Disaster Recovery Wizard.
The disaster recovery procedure requires that the Wizard temporarily stops the XProtect
Recording Server service. As long as a failover recording server is configured, it will take overrecording data until the Wizard starts the service again. To speed up the recovery procedure, youcan:• prepare a new disk, on which to recover the failed recording storage/archive
Note: The capacity of the disk should be enough to accommodate all backed up data. You caneasily calculate the needed capacity by checking the Camera data field in the Disaster recovery
storage pane of the failed recording storage/archive (see “Monitor Disaster Recovery Storage” onpage 37).

• attach the new disk to the recording server and create an NTFS volume on it, but DO NOT assign
a drive letter.
Note: If you need to recover data from recording storages/archives stored on more than one
volume on your recording server, attach as many new NTFS volumes to the server as needed orrepeat the recovery procedure for each volume that has failed later on.

Recover a Recording Storage/Archive Using the Wizard
Important: During the recovery procedure, the Wizard stops the XProtect Recording Server
service on the computer and when finished automatically starts it again. As long as there is a
failover recording server configured, it will take over recording data from the attached devices until
the recovery procedure finishes.

Manage Storage Extensions

When you extend the recording storage or archive of a recording server, you simply increase its
capacity with the free space on the cloud storage, network share or local volume you have added as
an extension. You can expand the capacity of a recording server’s storage with a nearline extension,from which data is transparently retrieved as soon as the connection speed allows, or an offline
extension, from which data is not retrieved immediately, but must first be rehydrated to anintermediate tier.
Once the retention limit you have specified for the respective recording storage/archive is reached,data is automatically deleted from it and from its nearline/offline extension to make way for newly
recorded data.
To extend the recording storage or archive of a recording server, you should do the following:• enable the storage extension (see “Enable Storage Extension” on page 50).
• configure what data should be automatically moved to the extension and made accessible fromthere (see “Configure Storage Extension” on page 56).
• turn on automatic Storage Bridge management of data between the extended recording storage/archive and the extension (see “Start/Pause Automatic Operations” on page 60).

Enable Storage Extension
To enable an extension, you should simply provide the credentials for access to the cloud storage,
network share or local volume, which will be used as an extension. If disaster recovery is alreadyenabled for the selected recording storage or archive, the same cloud storage, network share or
local volume is used as a nearline extension. Thus, there is no need to provide the credentials foraccess to the extension, but simply configure the extension and enable automatic Storage Bridge
operations on it.
The offline extension can only be on the same storage as the nearline extension and uses the same
credentials for access. You cannot enable an offline extension of a recording storage/archive, which
does not have a nearline extension already enabled. You also cannot enable an offline extension ofa recording storage, which has an archive, as moving groomed data to the archive would require
unnecessary retrieval of data from the offline extension.
Important: Storage Bridge does not allow you to use the same bucket/container (on cloudstorage) or folder (on network share or local volume) as an extension of more than one recording
storage/archive.

To change the type of storage extension or the credentials for access to it, you need to first disable
the current extension, following the steps in “Disable a Storage Extension” on page 54 and thenenable it anew. Keep in mind that if you want to change the type of storage extension or thecredentials for access to it of a recording storage/archive, which also has Storage Bridge disasterrecovery enabled, you must first disable disaster recovery too, following the steps on page 30.

•(
local storage only) Browse to and select the folder on the local volume, to which data fromthe recording storage/archive will be moved and then click OK.
Until you configure the extension, Storage Bridge uses the default parameter - data is
automatically moved to the nearline extension and is made accessible from there, when the used
space on your recording storage/archive reaches 95%. You can change this default parameter,
following the steps in “Configure Storage Extension” on page 56.
Important: By default, all automatic Storage Bridge operations are initially paused and you
can move data to the nearline extension only manually, following the steps in “Manually Manage
Data” on page 65. To let Storage Bridge automatically move data, follow the steps in “Start/
Pause Automatic Operations” on page 60.

5. (Azure only) Select whether files from the offline extension should be rehydrated to theStandard or the High tier.

6. In the Offline Extension Configuration dialog, click OK.

Until you configure the parameters for automatically moving data to the offline extension,
Storage Bridge uses the default parameter - data is made accessible from there, when it has notbeen accessed for 1 day on your recording storage/archive. You can change this default
parameter, following the steps in “Configure Storage Extension” on page 56.
Important: By default, all automatic Storage Bridge operations are initially paused and you
can move data to the nearline extension only manually, following the steps in “Manually Manage
Data” on page 65. To let Storage Bridge automatically move data, follow the steps in “Start/
Pause Automatic Operations” on page 60.

Disable a Storage Extension
When you disable a recording storage/archive’s extension, Storage Bridge stops moving data to it
both automatically and manually and all already moved data is accessible only directly from theextension i.e. cannot be retrieved through your XProtect VMS. Thus, if you attempt to review
footage from the extension using XProtect Smart Client, for example, the operation will fail.
Additionally, once you disable the extension, data on it is no longer automatically deleted once theretention limit set for the respective recording storage/archive is reached.
Important: If the recording storage/archive whose extension you disable also has disasterrecovery enabled, Storage Bridge stops moving data to the extension only automatically, but thedisaster recovery mechanism keeps on copying data based on the criteria you have specified andyou are still able to move data to and from the extension manually, following the steps in “ManuallyManage Data” on page 65.

You can disable just the offline extension and leave the nearline extension active. But if you disable
the nearline extension, the offline extension is automatically disabled too.

54

Enable Storage Extension

If you want to disable a storage extension, in order to change the credentials for access to it, makesure the new credentials provide access to data already moved there, otherwise it may remain
inaccessible in your XProtect VMS. If you want to disable the extension in order to change the typeof storage used as an extension, it is advisable to first migrate all data from your current extension
to the new one.
To disable an extension:
1. In the Site Navigation of XProtect Management Client, click Extension under Storage Bridge.

2. In the right pane under Recording Servers, click the recording server, whose recording storage

or archive’s extension you want to disable.

55

Manage Storage Extensions

Configure Storage Extension
To configure a storage extension means to specify the criteria based on which Storage Bridge
automatically moves data from the recording storage/archive to the extension. On both nearline
and offline extensions you can instruct Storage Bridge to move recorded data to the extension using
the “by age” criteria. On the nearline extension you can also utilize the “by size” criteria.
By age — Storage Bridge moves to the nearline or offline extension recordings that have not
be accessed on your recording storage/archive for a specified time interval. Once the “by age”
interval is reached for a specific recording, Storage Bridge copies it to the respective extension andthen replaces it on the recording storage/archive with a stub file, pointing to the copy on theextension and allowing it to be transparently retrieved upon request from the nearline extension or
rehydrated from the offline extension.
By size — Storage Bridge moves recorded data to the nearline or offline extension, when theused space on the extended recording storage/archive reaches a specified threshold. Once thethreshold is reached, Storage Bridge begins copying data to the extension, starting with the least
recently accessed files. Once a recording is copied to the extension, Storage Bridge replaces it on
the recording storage/archive with a stub file. The stub file points to the copy on the extension,
allowing it to be transparently retrieved upon request from the nearline extension or rehydrated
from the offline extension.
By default, nearline extensions use the “by size” method with a used space threshold of 95%. By
default, files are moved from the nearline to the offline extension, when they have not beenaccessed for 1 day. You can change the configuration of the nearline and offline extensions at any
time with changes applied immediately.
Additionally, when configuring an Amazon S3 or Azure offline extension, you can configure thefollowing options:Amazon S3 — change the archive retrieval option, choosing between Expedited, Standard
or Bulk.
Azure — change the rehydration priority for files on the offline extension, choosing between
Standard or High.

Start/Pause Automatic Operations
You can pause and start all automatic Storage Bridge operations for a specific recording storage/archive. It’s important to keep in mind that pausing/starting automatic operations concerns bothmoving data to the extension as well as backing up data, if disaster recovery is enabled for the same
recording storage/archive. Additionally, even if automatic Storage Bridge operations are started
for the extension, but later on you enable disaster recovery for the same recording storage/archive,
by default the automatic operations will be paused, until you manually start them again.
While automatic operations are paused, Storage Bridge stops automatically moving any data to theextension, but already moved data remains accessible from the extension, when you want to review
it in the XProtect Smart Client, for example. While automatic Storage Bridge operations are paused
for a recording storage/archive, you can also manually move data to the extension, following thesteps in “Manually Manage Data” on page 65.
Once you resume automatic operations, Storage Bridge immediately begins parsing data on yourrecording storage/archive and resumes processing the queue with files scheduled to be moved tothe extension.

Manually Manage Data

Using the Storage Bridge plug-in for XProtect Management Client, you can manually move data
between a selected recording storage or archive and its nearline/offline extension. This way you canmove data, which does not yet meet the criteria you have specified for the extension. You canperform manual operations for data recorded by all cameras on a selected recording server or justfor a selected one. You can also limit the number of recordings you perform the desired manual
operation on for a selected time interval only.
Additionally, the manual operations are indispensable for Storage Bridge’s disaster recovery
mechanism. When you recover backed up data, it is retrieved from the disaster recovery storage inthe form of stub files. To retrieve the actual recordings, you should either review them in the
XProtect Smart Client (on-demand data retrieval) or by executing a manual data retrieval job,
following the steps in “Recover Backed Up Data” on page 38.
You can perform manual data operations even if automatic Storage Bridge operations for therecording storage or archive have been paused. Manually initiated operations take precedence overautomatic operations, i.e. until the manual jobs queue is processed, Storage Bridge does not
perform any automatic operations.

Manually Manage Data
To manually manage data, you must create a separate job for each of the following operations:move data to be available locally - retrieve back selected data from the extension and make it
accessible directly from the respective recording storage or archive. You can use this operation toactually recover backed up data, in case of disaster.
Important: Keep in mind that the operation requires enough free space on your recording
storage/archive to accommodate all data retrieved from the extension.

bring back offline data - rehydrate recordings from the offline extension of a recording storage
or archive and make them accessible from the nearline extension, which allows their automatic
retrieval upon request from an XProtect Smart Client computer as soon as the connection speed
allows.
Note: If you execute this job for recordings which are not replaced by stub files on the recording
storage/the archive i.e. data is still available locally, Storage Bridge will move these files to thenearline tier of your cloud target, but their status will remain online until they are replaced withstubs, based on the nearline policy.

make data nearline to free local storage space - move data to the nearline extension and replace
it on the recording storage/archive with stub files, which point to the copies on the nearline
extension, but take no space on your local storage.
make data offline - move data from the nearline extension to the offline extension.

66

Manually Manage Data

Important: If you select to perform the above operation for recordings that are still stored onyour recording storage or archive, they will first be moved to the nearline extension and only afterthat to the offline extension.

Note: If some data for the specified time period does not yet meet the criteria for space
reclaiming, it will remain accessible locally and will be reported as offline only after it is replaced
by stub files.

You can create as many manual operation jobs as you wish. Once you create a job, it isautomatically added to the end of the jobs queue. Storage Bridge processes the queue one job at atime, starting with the first in line. You can monitor the jobs queue, following the steps in “Monitor
Manual Jobs Status” on page 69.
To create a manual data operation job:
1. In the Site Navigation of XProtect Management Client, click Administration under Storage

Bridge.

2. In the right pane under Recording Servers, click the recording server, whose recording storage

or archive data you want to manually manage.

the respective date or enter the respective start/end time.

5. Click Submit job.
6. When prompted, confirm that you want to manually move the specified amount of data between

the recording storage/the archive and the nearline or offline extension.
The job appears on top of the jobs queue pane. You can monitor its status, following the steps in“Monitor Manual Jobs Status” on page 69.

Monitor Manual Jobs Status
The Jobs queue pane displays the list of all jobs, arranged in descending order starting with themost newly added job. If you have allowed users to manually retrieve footage from the nearline/
offline extension through the XProtect Smart Client plug-in, the list also includes jobs initiatedthere.

The listing of each job gives you the following information:• type of the manual operation• date and time the job has been submitted• status of the job• Completed - the job has been successfully completed69

XProtect Smart Client Integration

The Storage Bridge plug-in for XProtect Smart Client provides you with the following features:• additional timeline data that displays the origin of the recording you are reviewing - local, thenearline extension or the offline extension.
• automatic retrieval of recordings from the extension - allows you to retrieve camera in real-time
while reviewing it on the timeline.
• manual retrieval of recordings from the extension - allows you to manually retrieve camera datafrom the extension to the recording storage/archive for a selected time interval.
An administrator of your XProtect VMS can enable or disable any of these features for a specificrecording server in the Storage Bridge plug-in for XProtect Management Client. For more details,
refer to “Configure XProtect Smart Client Integration” on page 72.
For more information about using the above options on an XProtect Smart Client computer, refer
to “Work with the XProtect Smart Client Plug-in” on page 75.

Configure XProtect Smart Client Integration
In the Storage Bridge plug-in for XProtect Management Client, you can enable or disable any of theXProtect Smart Client integration features for a specific recording server. Enabling or disabling anyof the features is valid for all XProtect Smart Client computers reviewing footage from the same
recording server.

Enable/Disable the Additional Storage Bridge Timeline
Data
When the Storage Bridge additional timeline data is enabled, it appears right below the default
XProtect Smart Client timeline on the Playback tab. It changes color depending on the origin of therecording currently being reviewed indicating to users if the data is from the nearline or offline
extension. When manual retrieval of data from the extension is also allowed, Storage Bridge allows
users to easily select the section of the recording they want to retrieve locally or to manuallyrehydrate from the offline extension.
When the additional Storage Bridge timeline data is disabled, but automatic retrieval from theextension is enabled, you can still review footage originating from the nearline extension.
By default, the additional Storage Bridge timeline data is enabled on each recording server.

72

Configure XProtect Smart Client Integration

To enable/disable the additional Storage Bridge timeline data:
1. In the Site Navigation of XProtect Management Client, click Administration under Storage

Bridge.

2. In the right pane under Recording Servers, click the recording server, whose XProtect Smart

Client integration features you wan to manage.

3. Under Smart Client Settings, do one of the following:• Select the “Timeline Color Monitoring” check box, to allow displaying the additional Storage
Bridge timeline data on each XProtect Smart Client reviewing footage from this recording server
and then click Apply.
• Clear the “Timeline Color Monitoring” check box, to hide the additional Storage Bridge
timeline data on each XProtect Smart Client reviewing footage from this recording server andthen click Apply.

Enable/Disable Automatic Data Retrieval
When automatic data retrieval is enabled for a recording server, a user reviewing recordings moved
to the nearline extension automatically triggers the retrieval of the currently reviewed data on therecording storage/the archive. The retrieval of data from the nearline extension is typically in realtime as determined by the network and connection characteristics. To retrieve footage from theoffline extension, you must first manually rehydrated it to the nearline extension. Storage Bridge
is able to partially retrieve data to efficiently play timeline video during reviewing operations.
When automatic data retrieval is disabled, should a user attempt to review footage stored either on
the nearline or the offline extension, the XProtect Smart Client player will report that the recordingis nearline or offline and will not play it.
By default, the automatic retrieval of data is enabled on each recording server.

73

XProtect Smart Client Integration

To enable/disable automatic data retrieval:
1. In the Site Navigation of XProtect Management Client, click Administration under Storage

Bridge.

2. In the right pane under Recording Servers, click the recording server, whose XProtect Smart

Client integration features you wan to manage.

3. Under Smart Client Settings, do one of the following:• Select the “Automatic Timeline Restore” check box, to let Storage Bridge retrieve data run time
while users review it, and then click Apply.
• Clear the “Automatic Timeline Restore” check box, to prevent users from retrieving data run
time when they attempt to review it, and then click Apply.

Enable/Disable Manual Data Retrieval
When you enable manual data retrieval from the extension, you allow users on XProtect Smart
Client to retrieve camera recordings within a selected period from the extension to the recording
storage/archive. The operation is identical to manual data retrieve operation initiated in the
Storage Bridge plug-in for XProtect Management Client and appears as a job in the manual
operation jobs queue.
Enabling manual data retrieval may be especially useful, when automatic retrieval is disabled, but
you still want to allow XProtect Smart Client users to be able to work with recordings available only
on the extension.
Note: Manual data retrieval operations retrieve all data for the specified time interval and not justthe frames currently being played as is with automatic retrieval of recordings.

When both automatic and manual data retrieval are disabled, should a user attempt to review arecording stored either on the nearline or the offline extension, the XProtect Smart Client player
reports that the recording is nearline or offline and does not play it.
By default, the manual retrieval of data is enabled on each recording server.

Work with the XProtect Smart Client Plug-in

Important: Whether or not a recording is available locally or only through the extension, theMilestone metadata is kept and the XProtect Smart Client timeline displays the markers forrecordings with or without motion.

Work with Nearline or Offline Recordings
Note: Keep in mind that retrieving data from most cloud targets may be associated withadditional costs.

As long as automatic retrieval of recordings is enabled for a recording server, you can play, export
or lock its recordings as you would normally do with recordings stored on the recording storage or
the archive. With nearline recordings (marked in orange in the Storage Bridge timeline) the
retrieve operation depends on the network and connection speed to the nearline extension. In mostcases this should be in real-time with minimal delay. With offline recordings (marked in blue on
the timeline), data must first be retrieved to the nearline storage tier. Once retrieved and in thenearline extension, the timeline data can be retrieved to the local storage and will display green on
the timeline.
If automatic retrieval of data is disabled for a Recording server, attempting to play or export or lockrecordings available from the nearline or offline extension will fail and the recordings will be
displayed in the XProtect Smart Client player with one of the following thumbnails:
A recording on the nearline extension

A recording on the offline extension

If manual retrieval from the extension is enabled for the recording server, to play or export suchrecordings, you must first retrieve them locally, following the steps below.

77XProtect Smart Client Integration

To manually retrieve nearline or offline recordings:
1. In the Playback tab of the XProtect Smart Client window, expand the MIP Plug-ins pane andnavigate to the Storage Bridge plug-in.
2. Under Storage Bridge, expand the node of one or more Recording servers and select the checkboxes of the cameras, whose recordings you want to retrieve.
