Can you install rsnaphot. Since I first heard about rsnapshot here, I've
been using it on my home system and on our WD MyBook. The biggest
advantage of rsnapshot is that it is configured through a standard
config file, and it uses rsync. Multiple backups effectively provide
incremental backup by using hard links, so that files in the daily.0 and
daily.1 directory that did not change are simply hard linked. It uses
the rsync --link-dest command to do this.
