System Backup vs Disk/Partition Backup

[pt58]

@pt58 - if that was the case, the difference would be a lot larger than slightly less than 20kB.

I would ask ADMIN... first of all, the System Image is SMALLER than the identical (same partitions) Disk image, not the other way around.  I'm still interested in what that slightly larger DATA is for the Disk image might be, generally speaking.

Yes sorry, I missed the fact that the difference was only 20kB!!
I was thinking the size difference was 20GB.
I'll crawl back under a stone.
