Backup 0X80070020 error

i installed win 7 and getting the error on backups. closed all programs, disabled avg free. it worked find with win 7 rc. any help?


The Windows Backup 0x80070020 error is a sharing violation error, there is a file or files that have open handles to another process or processes that are locking the file or files from being copied by backup.
someone I helped with this error had the issue with his C:\Users\<Username>\AppData\Roaming\Microsoft\Windows\Cookies\index.dat file.
I had to use Process Monitor to find out which file was actually locked. The only way I managed to resolve it was to create a selective backup to exclude the C:\Users\<Username>\AppData\Roaming\Microsoft\Windows\Cookies folder with that persons permission.
Just a note that it might not be that file that is locked, it could be any other file being backed up.
The Process Monitor filters I used were:
Command Line contains C:\windows\system32\svchost.exe -k SDRSVC
You can download Process Monitor from here.
