[TriLUG] Bit rot detection without ZFS/btrfs?

[Len Boyle]

" But what happens if there's bit-rot on the destination machine...."

If I understand what the zfs folks were saying, this is the real issue. Once the bits on the file system blocks were corrupted, any copies were corrupted. 
And the bits could be corrupted not sitting on disk, but in the transfer from the disk to memory, in memory or any where in the path that did not have error detecting hardware that was working correctly.

But what happens if there's bit-rot on the destination machine....

On second thought, let's not go there.
