Thanks for your answer.

I can mount all the partitions (ubuntu via the
mount_ext2fs command).

So, I could use DD, but then I would have to do this
every time I want to be synchronized.

This would be the firts thing I could try, when the
disk drive arrives. Then I would know I have at least
a  copy of the full disk.

Hmm, I have to think this over, but nice knowing this
is an option.
