I will point out that this discussion has transgressed beyond the realm
of rsyncrypto, and into the rsync turf. However:
Using rsync, you can compare with files in one directory, but write the
results to another directory. If you do that, you can create a secondary
director of just the files that changed. Use "cat" to copy them back to
the original location, and hopefully that would salvage your zfs usage.
As I said, however, this is more rsync than rsyncrypto related.
As a side note, please don't disable gzip in rsyncrypto. that feature
was meant solely for the tests. Certain entropy assumption behind the
cryptanalysis of rsyncrypto do not hold when the entropy of the file is
low. In other words, when rsyncrypto does not compress, it is less
secure as an encryption.
