For incremental backups, you could do something as simple as rsync or
use one of the many backup utilities around (amanda, bacula,

My personal choice is BackInTime because it's easy for me to set up and
manage, but it might not fit your needs.
Thanks, Joe, for your reply. BackInTime seems to be a great backup
tool -- I am going to give it a try -- , but I was looking for a
cloning application (with differential /incremental backup).
Had you considered using a qcow2 disc image file? Stored on whatever your
external drive is. Then for an incremental, just make a new .qcow2 which uses
the previous one as a base, just as one does with VM snapshots. There must be
some kind of tool which will read/write to a .qcow2 as an image: you'd then
just need to do a "sparse" disc copy to the new incremental .qcow2 i.e. read
your source drive in blocks, read the .qcow2 in parallel, only write changed
blocks to the qcwo2.
Regretably (appallingly), last time I looked there was no facility to attach
such an image as a block device, which would make all of this trivial (not to
mention many other things).
Would be happy to hear if things had improved.
