Eric, 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... Steve Fettig Eric F Crist wrote: >I've been looking for a solution for this, as well.
