Pre-Freeze and Post-Thaw Scripts

You can specify what scripts Veeam Agent for Linux must use to quiesce the OS on a protected computer. The pre-freeze script quiesces the file system and application data to bring the OS to a consistent state before Veeam Agent for Linux creates a volume snapshot. After the snapshot is created, the post-thaw script brings the file system and applications to their initial state.

To specify pre-freeze and post-thaw scripts for the job:

1. At the Guest Processing step, select the Enable application-aware processing check box.
2. Click Applications.
3. In the displayed list, select a protection group or individual computer and click Edit.

To define custom settings for a computer added as a part of a protection group, you must include the computer to the list as a standalone object. To do this, click Add and choose the computer whose settings you want to customize. Then select the computer in the list and define the necessary settings.

4. In the Processing Settings window, click the Scripts tab.
5. Select the Enable script execution check box.
6. In the Pre-freeze script and Post-thaw script fields, click Browse to choose executable files from a local folder on the backup server.

Veeam Agent for Linux supports scripts in the SH file format. During the backup job session, Veeam Backup & Replication will upload the scripts to the /var/lib/veeam/scripts directory on each Veeam Agent computer added to the job and execute them on these computers.
