Scenario: Windows Server 2012 Backup to NAS Failing

“I’m regretting that I have met the problem Server 2012 cannot backup to NAS. I use Windows Server 2012 (r2) and I was trying to backup it to NAS. However, it is failing to the NAS. I tried to schedule backup Bare metal recovery, System state, System reserved, and Local disc (C:) and the advanced option is VSS Full Backup. The destination is the NAS which is a remote shared folder. However, I received those warnings while backing up:

● There was a failure in preparing the backup image of one of the volumes in the backup set

● Detailed error: The process cannot access the file because another process has locked a portion of the file.

I just want to schedule a full backup of the Windows 2012 r2 server to the NAS. How can I make it?”
