I suppose it depends on what you want to achieve. There are various 
options such as mirroring to another raid6 array (ie, RAID60) but really 
that isn't a backup, it's another replica.
I use backuppc for my backups, it works well under linux with rsync, I'm 
sure there are many various options (including amanda which I've used in 
the past). Ultimately, it depends on your requirements, backups vary 
significantly depending on needs/etc.
