The raid 1 setup is what at least a few of us on the list use.  For me,
it works like this:

My filesystem is raid 1 (via md) with 3 disks.  Two of the disks are
internal and one is in an sata hot-swap enclosure.  Whenever I want to
take a backup offsite, I shut down the machine, pull the third drive,
replace it with a new one, and start it back up.  Then I just need to
tell md to rebuild onto the new drive and then take the old one
offsite.  I always have at least two active drives in the raid, so I
don't have to worry about a disk failure during the rebuild.
