PowerProtect Data Manager 19.11 File System 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 and 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"}
