If the aim is to ease the pain of recovery after the occasional disk 
crash rather than acheive 24/7 availability then automated backup to 
another filesystem would seem satisfactory. If you add automatic 
archiving to the backup system and from that to tape/dvd then you have 
the advantage of being able to recover from certain instances of finger 
trouble and other nasties that raid doesn't do for you.

Sadly my homebrew system for doing this is still lacking a few Tuits, 
and I don't know of any such systems available Out There (tm)
