rsync - May 2005 - easiest way to do incrimentals?

With the --backup and --backup-dir options that means that it copies out
the files that are going to be changed before overwriting them to the
specified directory?

Yes.  That gives you a hierarchy with just the old version of changed
files in it.  It can be better to do a --compare-dest or --link-dest
into a new (empty) hierarchy, as this gives you a hierarchy with either
(for --compare-dest) just the new version of changed files in it or (for
--link-dest) all the files with identical files hard-linked together
with the older files.  There are backup programs built on rsync that
have worked out details such as this for you (some are mentioned on the
resources page of the rsync website).
