Note that ZFS can detect the bit rot, but you'll need to actually run some kind of RAID (in this case RAID-Z) to have it fixed automatically. And if you do want bit rot detected on a timely basis, you'll need to have the data on the drives scrubbed on a regular basis (weekly? monthly?, not sure what is sufficient).

You can set the "copies" property to 2 or 3 even with a single disk, so if one dodgy sector blats one of your files, ZFS can still recover: https://blogs.oracle.com/relling/entry/zfs_copies_and_data_p...
