Error Message 20088

The Hyper-V VSS writer does not support the taking of data consistency snapshots on this virtual machine. As a result, the backed up data may not be in a consistent state. (For more information about creating application-consistent snapshots, refer to the product documentation).

Symptom

Backup job couldn't take data consistent snapshot for backup so that backed up data may be inconsistent.

Solution

Make sure that the VM supports consistent backup. Check UDP Solution Guide for the prerequisites of application consistent backup.
