[OpenAFS] fine-grained incrementals?

[John S. Bucy]

I'd like to use something like the following as a way to get
fine-grained incrementals/versioning of volumes; the mtime-based
incremental dumps presumably have to dump a whole file even if you
only change 1 byte.

I'm thinking of the following protocol:

1. take a full volume dump daily
2. use a (smart) binary diff system like rdiff (xdelta3?)
to generate a delta from the previous day's full dump
3.  delete the previous day's dump.

It seems like the dumps would have to (at a minimum) have all of the
objects appear in the same order every time for this to work reasonably.

Thoughts?
