Hello,
I have located the log file for the WindowsServerBackup (C:\Windows\Logs\WindowsServerBackup)
The log file has additional info:
Error in deletion of [C:\System Volume Information\$CBT2] while pruning the target VHD: Error [0x80070020] The process cannot access the file because it is being used by another process.
I have then tried deleting the above file without success
I have taken ownership and given myself Full Control
I have also given SYSTEM Full Control
When I try to delete the file, nothing happens. No error, no dialog box.
I have re-run the backup after giving SYSTEM full control and the backup continues to fail
