I am currently setting up a customer with a Dell VRTX server with 2 nodes. Both nodes contain Server 2012 R2 and are clustered with high availability Hyper V. Sepparately to that, I have a synology disk station for local backups and I have connected them to the nodes through iSCSI and have created another CSV storage for the backup. When using the windows builtin backup I keep getting event id 521 from backup source. Enclosed is the reading:
"The backup operation that started at '2015-06-20T21:28:21.792000000Z' 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 '0x81000113'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved."
Can anyone shed some light on this? the VM's are housed within the VRTX shared storage of the chasis. The iSCSI connections to the synology are planned strictly for backups. Any help would be greatly appreciated.
Thank You!! =)
