Windows Server 2012 R2 Backup Failing.

Hello all,

I would like to ask for some help regarding the system backup on a Windows Server 2012 R@ which is failing, either when I run it manually or scheduled. I also run WSUS on this same server. There're a few things that I have done before the backups stopped working and I think they are related. I would like to know if anyone could help me on how to fix this. Thanks.

1. I reinstalled WSUS and WID

2. I changed the Local drive which the backups are exported. 

When I look at the logs I see that there are a bunch of database errors at the time of the backup:

The backup operation that started at '‎2016‎-‎12‎-‎05T15:53:57.698000000Z' 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.
