But ZFS would help.  If the file is corrupted by a disk, then the checksum
almost certainly will fail and the copy from an alternate disk in the
filesystem will be read and is very unlikely to be corrupted at the
same time.

I like rsnapshot too, but it is worth remembering that if your backup
of a file is ever corrupted by the disk, you won't get a new copy when
using rsnapshot/rsync in the typical mode.
