Incremental\Differential backups of Hyper-V virtual machines residing on Cluster Shared Volumes (CSV) may fail if the "Hardware" provider is used for the Advanced Open File Settings (AOFO).

Problem

When performing Incremental\Differential backups of virtual machines on a Hyper-V cluster, the job may fail when "Hardware" is chosen for the snapshot provider. (Figure 1)   

(Figure 1)

Error Message

Final error: 0xe00095b4 - Incremental\\Differential backup methods are not supported for this VM. The backup job failed, since the option 'to fall back to a full backup' was not selected.

V-79-57344-38324 - Incremental\\Differential backup methods are not supported for this VM. The backup job failed, since the option 'to fall back to a full backup' was not selected.

Cause

Use of the Hardware provider is not currently supported for backing up virtual machines that reside on Cluster Shared Volumes (CSV). 

Solution

  Use "Automatic" for the AOFO settings in the backup job definitions. This will allow the correct Cluster Shared Volumes writer (CSV) to be used for the backup. (Figure 2)
