Dual HD writing

[Neelands]

I'm looking for info on dual writing to HD's. As in if 1 fails I can swap in the second and keep going.

Google RAID 1. Note that RAID isn't a backup, but RAID 1 allows you to do what you're looking for. You don't swap the hard disk; you simply replace the failed member and the controller will rebuild the array.
