PowerProtect Data Manager 19.9 File System Agent User Guide

Prerequisites for restore of file system assets

Review the following requirements before performing centralized image-level or file-level restores of file system assets:

• Both the PowerProtect Data Manager server and client must be at a minimum version of PowerProtect Data Manager 19.3.
• Ensure that the File System agent is not installed and running on the target volume.
• Ensure that there is sufficient space on the target volume for the restore.
• Ensure that the target or destination volume is not read-only.
• Cross-platform support for centralized file-level restore is not supported. For example, you cannot recover a Windows backup on a Linux platform and the opposite way.
• Review the section Supported platform and OS versions for file system file-level restore.

Caution regarding image-level restore of a system volume to a system volume

Running an image-level restore from the backup of a system volume to a target volume that is the same or different system volume can cause the following problems:

• Files in use are not restored.
• The file system host machine may become unstable.

Therefore, in such a situation, it is recommended to perform a file-level restore for the required files/folders only.

Increasing the restore timeout

By default, the mount operation times out after 30 minutes and the backup copy is unmounted. When running file-level restores of large files, you can increase the restore timeout. Perform this task if file-level restores for large files timeout before completing.

1. Create a file with the name browsersvc.cmd in one of the following locations:
   • On Windows, C:\Program Files\DPSAPPS\fsagent\settings
   • On Linux, /opt/dpsapps/fsagent/settings
2. Add the following line to the file, and specify the same timeout value, in minutes, for both variables:

   {"-idletimeout":"timeout", "-resexpiry":"timeout"}

   For example, enter this line to set the restore timeout to 60 minutes:

   {"-idletimeout":"60", "-resexpiry":"60"}
