Workarounds

• Check integrity of the file system on guest OS and retry the job
• Run image backup without file level indexing
• If file level restores are required, restore the VM renaming it and extract the files from this VM
• Install NetVault client in the affected VM, then run backup using the file system plugin

Status

Waiting for fix in a future release of NetVault Backup
