Cannot restore files from deduplication-enabled backups of Windows 2012 or later virtual machines

Article ID: HPV0022 You cannot restore files from deduplication-enabled backups of virtual machines running on Windows 2012 or later operating systems.

Symptom

When restoring from a deduplication-enabled backup of a virtual machine running on Windows 2012 or later, a file-level restore operation completes successfully but creates only stub files.

Cause

Virtual machines running on Windows 2012 or later operating systems have their own native deduplication capabilities. If the virtual machine has native deduplication enabled, file-level restores from backups are not supported because the backed up files are stored only as stubs.

Resolution

 To restore files, use one of the following methods:

  • To retrieve files from a backup for a Windows 2012 or later virtual machine that uses deduplication, select the Virtual Machine files option in the Restore Options dialog box to restore the virtual machine disk that contains the files.
  • To enable file-level backups, install a local File System Agent on the Windows 2012 or later virtual machine .

As a result, the data is backed up in a rehydrated state so that you can restore file-level data from the backup.
