Block-level ("differential") copying utilities (Windows)?

I do quite often update metadata to my files, and I have one backup set where I commit these changes quite frequently (... and one which has not been overwritten for years, but that is a different story).
There are utilities which copy only blocks with differing checksums, rather than full files. Quite a few of these do however use their own archive formats, and it seems like I cannot use the backup disks for playback (which I do, this set of backup drives are hooked up to my work computer, at least I then know when the drives fail).

So, are there any which operates on files as files but only update blocks, much like a tagger only overwrites the metadata section of the audio files?
And, is there any way I can in batch set padding on my FLAC's?

Sounds like rsync to me. Have you tried that? If you want a front-end for all kinds of storage and transfer mechanisms, Duplicity might be interesting.

Depends on what you want to do exactly. There are quite a few command-line options considering padding for metaflac.
Music: sounds arranged such that they construct feelings.

On *nix, rsync is surely the way to go. There is a Windows/cygwin port of rsync which is included in DeltaCopy. I never used it, though.
