I would very much like to see the possibility to make only incremental
backups, no more full backups required.

The main point is to (dramatically) decrease the needed bandwidth, which
 makes the difference between being able or not to use Bacula for
relatively large storage devices on relatively slow internet connections
(with relatively few changes/day), like almost all of my backup targets.

Ofcourse Bacula can do this if you simply never cycle the original Full
Backup and retain *all* incremental backups since the beginning, but
this is not what I mean. I mean sort of like rsnapshot does (using the
--link-dest option of rsync). That way you need only incremental
backups, but you end up with essentially a collection of full backups.
Backups that are even extremely disk space efficient. And you can delete
as many of them as you like, without harming the other copies.

So why not simply use rsnapshot then, if that's so perfect? Well, it
isn't that perfect. Bacula has some great advantages with regards to
scheduling, reporting, the separation of sd, fd, dir and console,
filesets, etc. So implementing a "--link-dest" kind of feature in
Bacula, *that* would be perfect :)

I saw some discussion on this topic about one month ago, between Eli
Shemer and Dan Langille, but I haven't heard a follow-up since.
Nevertheless if something like this could be built, it would make me
very happy :)

Kind regards,

Erik.
