Backup Job Scripts

You can instruct Veeam Agent for Linux to run custom scripts within the backup job session. In contrast to the standalone version of the product that can run custom scripts on the Veeam Agent computer only, Veeam Agent for Linux operating in the managed mode supports the following types of scripts:

Pre-Freeze and Post-Thaw Scripts

Veeam Agent runs these scripts before and after creating a snapshot of the backed-up volume. For example, the pre-freeze script may quiesce the file system and application data to bring the Linux OS to a consistent state before Veeam Agent for Linux creates a snapshot. After the snapshot is created, the post-thaw script brings the file system and applications to their initial state.

You can specify pre-freeze and post-thaw script settings at the Guest Processing step of the New Agent Backup Job wizard. For details, see Backup Job and Snapshot Scripts.

During the backup job session, Veeam Backup & Replication uploads the scripts to each Veeam Agent computer added to the backup job and executes them on these computers. The scripts run in the same way as in the standalone version of Veeam Agent. To learn more, see the Backup Job Scripts section in the Veeam Agent for Linux User Guide.

Pre-Job and Post-Job Scripts on Veeam Agent Computer

Veeam Agent runs these scripts before the backup job starts and after the backup job completes. You can use pre-job and post-job scripts, for example, to quiesce an application for the time when the backup job session runs on the Veeam Agent computer.

You can specify backup job script settings at the Guest Processing step of the New Agent Backup Job wizard. For details, see Backup Job and Snapshot Scripts.

During the backup job session, Veeam Backup & Replication uploads the scripts to each Veeam Agent computer added to the backup job and executes them on these computers. The scripts run in the same way as in the standalone version of Veeam Agent. To learn more, see the Backup Job Scripts section in the Veeam Agent for Linux User Guide.

Keep in mind that scripts of this type are supported for computers that run Veeam Agent for Linux 4.0 and later only. Earlier versions of Veeam Agent for Linux do not run pre-job and port-job scripts obtained from the backup server.

Pre-Job and Post-Job Scripts on Backup Server

Veeam Agent runs these scripts before the backup job starts and after the backup job completes. You can use pre-job and post-job scripts, for example, to throttle activities of some resource-consuming services on the backup server during the backup process.

You can specify backup job script settings at the Storage step of the New Agent Backup Job wizard. For details, see Script Settings.

During the backup job session, Veeam Backup & Replication executes the scripts on the backup server. The scripts are executed on the backup server under the account under which the Veeam Backup Service runs (the local System account or account that has the local Administrator permissions on the backup server).

Script Execution Order

If you specify both pre-job and post-job scripts that run on the backup server and pre-job and post-job scripts that run on the Veeam Agent computer, the scripts will be executed in the following order:

  1. Pre-job script on the backup server
  2. Pre-job script on the Veeam Agent computer
  3. Pre-freeze script
  4. Post-thaw script
  5. Post-job script on the Veeam Agent computer
  6. Post-job script on the backup server
I want to report a typo

There is a misspelling right here:

 

I want to let the Veeam Documentation Team know about that.
