I guess that must be the case, otherwise my "M:\Disk 01" archive would be essentially empty as it contains an exact copy of my "E:\Disk 1" archive which is an exact copy of my D:\ disk drive. If it were de-duplicated based on what had been backed up to the E: archive, the M: archive wouldn't have anything in it because the entire M: archive is a duplicate of the E: archive.

You're making my head spin.

Here is what I know: in the 3-step setup I described in my previous post, if step 3 involved choosing two locations, then yes, I would have a full backup set in both locations. If my local drive had failed, I could get all the exact same data from the cloud.

I've sort of lost the thread on how your system has been set up. Sorry about that...
