A server with Windows server 2012 R2 qwith deduplication and server backup rol.

I have activated deduplication on the target backup volume (on the same server) and in the deduplication exclude list appear the folder "\WindowsImageBackup" automatic, this is normal?

Regards.

Hi,

It is normal. Generally we do not want Dedup to work on backup target folder as a corruption in Deduplication database will affect all dedupped files. Most files should be backed up so it is acceptable from a corruption but we will not "backup a backup".
