Microsoft recommends that certain files not be backed up as part of a File System backup. These files are visible in the registry under:

Zmanda Cloud Backup honors this recommendation. Additionally, ZCB adds a few exclusions regarding its own files.
ZCB will also ignore its own files in a backup.



These files will be ignored automatically by ZCB in all File System backups. No additional action is required.
