Hello Everyone, 

My server running in windows server 2012. Recently the Window Backup Failed due to

Error in deletion of [E:\System Volume Information\001.dat] while pruning the target VHD: Error [0x80070020] The process cannot access the file because it is being used by another process.

Anyone facing this issue before?

I haven't met this problem because I used the software AOMEI Backupper to backup my files. AOMEI Backupper has a version for Windows server-AOMEI Backupper Server, you can try it. It may solve your problem. Hope this could be helpful. Good luck!

E:\System Volume Information\001.dat is not a system file. According to my search result, it could be a file created by antivirus applications (Kaspersky).

Please test to disable Kaspersky (or any other security application) and run the backup again to see the result.

Or you may need to exclude this file in your backup schedule to workaround it. It is not a system file so it should not affect the system in a restoring.
