Maybe you should consider using a filesystem that integrity-checks everything written on disk and supports object-level replication 
I've looked at Avoton stuff a bit (Atom server, basically), unfortunately it looks good but out of my price range (500CHF for a MB+CPU combo). Has AES-NI and ECC support though, which would have been cool but I'll have to do without it.
