Depending on which is available, duplicity keeps either SHA1 or MD5
hashes on the volume files and checks it during the recovery.  You'll
get a warning if they don't match.  This does not cover the signature or
manifest files though.  We need that as well.

What we need also is par2 or equivalent to provide recoverability in the
presence of errors.  It's in the plans for a future release.
