If it does't have to be offline for long durations, software raid + adding a new drive every once in a while, and discarding failing drives is pretty foolproof.

The issue with (software) raid is you have no idea if what you're copying isn't actually corrupted. If the filesystem isn't checksumed there's no guarantee.

  One can use software RAID5/6 to get the checksumming.
