[colug-432] disk recovery

[Brian]

I don't perform a specific check, but rsync gives both the total size of
files backed up, and how much it actually moves.  It only moves changed
blocks.  So if it reports a total size of 900 MB, but says it only moved 2
MB, I can be pretty sure the files aren't encrypted.  There would be lots
of changed blocks if the files were being encrypted.  Plus it gives me a
statement of how many files were changed.
