It's not clear what do you want in fact.

Incremental and differential backups are supposed to transfer only
modified files.

Then there are "base jobs" which can be used to define a minimal subset
of files which is supposed to be the same for several clients; this
also can be used to transfer only missing/changed files during backups.

If you're trying to formulate something like "FD-side deduplication", I
think it's not possible (and I doubt it'll ever be).
