I use RAID 0 on my workstation for speed.  And I use unison (similar to 
rsync) to create regular backups of critical documents etc on a remote 
machine.

I also use mondorescue occasionally to create bootable snapshots of my 
workstation (and some servers), so that I can rebuild it easily if ever 
necessary.

Backups & use of RAID models are all about risk - how much do you value 
the software/files on your machine vs how much work do you want to do to 
and $ you wish to spend to setup backup regimes, buy extra hard 
drives/hardware/electricity etc?

Incidentally I investigated fakeraid for another server, but in my 
opinion it is still no better (probably worse) than software RAID, which 
I find works perfectly well & fast enough for my use.  I don't boot RAID 
on anything though.
