Re: Is there a way to get a different return-code when incremental backup didn't actually find a difference?

Denis,

Thank you for the quick answer.
I have several filesystems where occasionally, new files will be added. Most of 
the time, they are quite static and nothing actually changes.

I agree the filesize doesn't matter much, but the additional files to go through 
when restoring will be quite a lot and I'd prefer to already remove these 
"empty" backups before uploading them to cloud-storage (where they will incur 
costs for storage and retrieval)
