Well, I've been using amanda since 1998, and it was fairly mature then, 
and its always done what I wanted.  I do backup to disk, but if I wanted 
offsite, then copying its backup and index files to an external drive 
offers bare metal recovery completely up to the date of the last backup 
the way I do it.  As is, I just use a separate disk from the OS's disk as 
virtual tape.  Works a treat.

I looked at Bacula/Amanda - which are great systems if your focus is
tape or backup to disk.  But neither of them had good support for
"backup to disk, rsync to offsite".

rsnapshot / rdiff-backup are just better at creating backups which are
rsync-friendly over the WAN.  Which also means you can easily push the
backups to USB drives without having to wait hours and hours.

Second that. It's great tool that keeps an actual sync
(rsync-based) of the data-directory and the metadata (delta) in a
seperate directory to restore data from any date.

Alternatively, you might want to take a look at bacula, which was faster
in most cases (development seems to have stalled, but there is a fork I
have not had time to take a look at: bareos). However, I liked the
rdiff-backup way because I can restore files via scp or rsync (most of
my requests were like "please restore from yesterday") or if I want to
restore data from a certain date I can use rdiff-backup from command
line (bacula is much more complex, and you need the admin tool to
restore files - rdiff-backup works from command line locally or via ssh/keyauth)
