Situation: The client use Veeam Agent Backup to do the files level backup. They get this error message: Failed to index file system.
Troubleshooting: Disabling “Enable guest file system indexing” should fix the problem. Alternatively, Install Veeam Backup Enterprise Manager.
FYI ‘file system indexing’ is used for 1-click restore in Veeam Enterprise Manager, so if you don’t use Veeam Enterprise Manager you can leave this option disabled (unchecked).
