Well, I don't know *why* they ask me to do integral backups of their images,
but I simply can guess: it's because they eventually want to be able to go
over to that remote location with their USB HDD and copy that image over,
place it on the server and run it!

Could you please depict a bit more in depth this part?
AFAIU, if I do too many incrementals I'd have to take in account growing
backup times from differential to differential.
On the other hand, if I'd do only full backups, I'd have way longer backup
times, for *each* single backup shot.

Is the above right or am I missing something?

Thanks again and kind regards,
