The provider was unable to perform the request at this time. This can be a transient problem. Retry after <parameter>seconds.

Symptom

Job was failed.

Solution

Check event logs for more details. One reason for this message could be a source volume, which is 64 TB or larger. This size is above the Microsoft limit for VSS snapshot functionality. If the data on the volume allows it, shrinking the volume from the Microsoft Disk Management to a partition size below 63.9 TB would allow VSS snapshots to work.
