Hi,
Windows Server Backup fails on Windows Server 2012-R2 with this message:
"The backup operation that started at '2015-08-27T22:30:39.228000000Z' 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 '0x8078006B'. Please review
the event details for a solution, and then rerun the backup operation once the issue is resolved."
Found some articles about this error pointing to Windows Backup not supporting 4K drives. In my case, it is a 4K drive but I also confirmed that Windows Backup DOES support it on Windows Server 2012+ (https://support.microsoft.com/en-us/kb/2510009).
I also re-installed the feature and checked for system and drive integrity.
Physical Hard drive is a WD 4TB drive. Volume is a 2TB basic partition (the only partition on that drive, along with a 9,39GB System Reserved volume). The rest is lost.
Thanks for any help.
Thomas.
