There's support for that in btrfs (change log streaming). And I think XFS has something similar.

Yeah. Changelog streaming sends you a pile of stuff in a format that only btrfs can read, though, doesn't it? I'd rather know what on the fs has changed, so my backup program can do its deduplicatory magic on it in such a way that I can restore file-by-file later if I want to, as well as in a single huge lump. Otherwise, I might as well just be using horrible old dump(8)...

The btrfs code is all open, so if you wished to make your own tool to read it you probably could.

Ooh! Yeah, that's useful. I somehow never noticed find-new.
