I think what you are looking for is drive mirroring (which I think is known as RAID 1). Although I have never done this myself, the Handbook seems to give good pointers at:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/raid.html
For more information on mirroring control, the man of ccdconfig:
http://www.freebsd.org/cgi/man.cgi?query=ccdconfig&sektion=8
If you are looking at backup *philosophy* in general, though, mirroring doesn't cover it because a catastrophic system failure would simply be copied to the mirrored drive (or worse, in the case of an electrical failure - i.e. drive, board, controller burnout - you would lose everything). I only mention this because it has happened to me and I have been extremely thankful for my tape backups...

I've been looking for a solution for this, as well. I want RAID level copying, so I can just swap harddrives and be back up and running. If I have two identical 160GB HDD, on the same IDE cable (pri/sec), how would I accomplish this, and roughly how long would it take? Figure both HDD are full.
Would I activate this by a script?
