Thx Jon, that's exactly what I did to verify. Basically if I change the Source location of the backup to the root folder (instead of individual files under the root folder) then Cloudberry realises that essentially the paths are the same and it does not upload all the files again.

...ok...sorry to harp on this, what if I was backing up individual folders inside Drive E: and then wanted to change the Backup source location to Drive E only and remove the individual folders from the backup source location. Will it upload all the folders again or know that they're already backed up? See below:

Original Backup (Name - Backup Photos):
Folder A:
Folder B:
Folder C:

NB: Folder A, B, C are all inside Drive E:

New Backup (Name - Backup Photos)
Drive E

Excuse the basic questions but I'm only getting to know how C'berry works.
Cheers,
Altay

Thx Matt. Is there anyway to trick the software so as not to upload the file again?

Thx again Matt. Much appreciated.

Altay.

Matt - thanks for the explanation! Yes, I may have used S3 in the first instance.

Is there a way to specify when to do another FULL backup or again do I not get the option because of Glacier and everyting is incremental?

Cheers,
Altay
