Windows Server 2012 R2 Server Backup fails when tried to take System Image, Bare Metal Recovery backup using Windows Server Backup tool. I am trying to save the backup to a network shared folder. The Volume Shadow Copy and Microsoft Software Shadow Copy Provider services are set to Manual.
The error message : The backup operation failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '0x80780021'. Please review the event details for a solution and then rerun the backup.
So far, I have tried the following:
1. Set the Shadow copy to use Maximum size as No Limit. (on both local C: drive and shared drive)
2. Ran chkdsk C: /f - and found no errors
3. vssadmin list writers - lists all the writers as No Error
4. Created 2 REG_DWORD entries in HKLM\Software\Microsoft\Windows NT\CurrentVersion\SPP
CreateTimeout - 1200000 (decimal)
IdleTimeout - 1200000 (decimal)
Please let me know if I need to do anything else to resolve this issue. Any help is appreciated. Thank you.
