Event ID:521
The backup operation that started at '2013-12-17T11:00:52.838000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '0x8100010C'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
