Device could not be snapped because it contains an active cache file

I have some Exceptions in my daily backup log:

Server-komunal is windows 2000 server operating system.
Do you have any suggestions?

To get rid of the active cache file you probably need to reboot. If you can't reboot, you could try to use Process Explorer to close the handle on the snapshot files.

To avoid this problem for the future, make sure that your antivirus solution is excluding *.VSP from scheduled and on-access antivirus scan. Also make sure to exclude the "Backup Exec AOFO Store" folder at the root of the C: D: and E: drive.
