Yet another 0x80070020 error.
When trying to backup my Windows 7 host, I get the following error:
The backup failed. The process cannot access the file becaue it is being used by another process. 0x80070020
I have manually selected the files to back up, and removing Additional Locations -> AppData folder from the files being backed up allows it to finish.
I suspect that there's a file in that set that's preventing backups from working, either because it's in use or the permissions are wrong. Is there any way to find out which file from the .etl file? tracerpt.exe doesn't give the information and there's no information in the event log or application log about which file is causing the trouble.
