-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --checksum generally takes a lot longer than --size-only. A delta transfer generally goes quicker than a checksum. However, if you want to make a list of what is corrupt a checksumming utility that is less stupid than rsync can be useful. I say that because rsync's - --checksum is entirely unintelligent. It will checksum every single file on both ends including files that only exist on one end and files that shouldn't match (the size is wrong). At the end of --checksum you will still have to do the delta xfers that you would do without it.
OTOH, you are using --dry-run. If you are trying to generate a report about what files are corrupted then only --checksum an do that. It will just do it in the dumbest/slowest way possible.
