Object not found or could not be accessed

I am having exactly the same problem as described in this post (which is closed and locked):

All my backup jobs have status "failed" because they can't access C:\Windows\SoftwareDistribution\Download

on the Windows server 2008 R2 machines. I know that this directory is used by Windows Update - and if I move those

files out of that directory, the backups work... until the next time Windows Update puts something in the folders.

There is so much maintenance with this... any suggestions? I already tried to exclude C:\Windows\SoftwareDistribution

from the backup job, which it completely ignores, and fails anyway.

How exactly did you try to exclude this particular folder & did you setup a global exclusion ?

I don;t think setting up an exclusion will work as the files under Windows directory usually ets backed up as a "system files" component of System State,

Can you try creating a new selection list and see if it works. As it seems that no one have found the exact cause or the resolution of the issue yet.

If this answers your query, please mark it as success.

Thanks & Regards

This could also be caused by a disk corruption.  Run a chkdsk /f on the disk.  The /f parameter is important as it fixes any error.

I have tried setting up a new selection list. This is a problem that occurs on all my Windows Server 2008 R2 machines, so I don't think it is a disk corruption problem.

When I Google "C:\Windows\SoftwareDistribution backup", it seems like a lot of backup software has problems with this location. So apparently Windows does something "special" here, such that backup software doesn't have access to it. It seems that BackupExec can't handle this, and therefore it fails.

There must be other people out there trying to make backups of Windows Server 2008 R2?

By default, Windows creates a list of exclusions stored under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup

See if there is a key called SUS Client with the value - %SystemRoot%\SoftwareDistribution\* /s

Also, what was the exclusion created by you in BE ? Was it similar to \\*\*\win*\softwaredistribution\downloadl\*.* /subdir /exclude  ?

EDIT** These files are not backed up as they are locked for exclusive usage by Windows.
