It's A Digital Disease!

I'm looking to start ripping my movies to an external harddrive, and I'm thinking I'll have three identical drives in total, so I've got backups and the option of detecting and recovering from bitrot (or any other kind of corruption). Assuming I've got all three drives accessible over the network at any given time, I would want to use something like rsync (I guess?) to actually sync them up, but I really want a way to detect and recover automatically when a corruption occurs. Is there a good piece of software out there that does just that? Or maybe syncs files and does the recovery at the same time?
