The point is actually to fix resumption, not memory usage; memory
usage is already quite good in 3.0. That was never a goal of rsync
as far as I'm aware; resumption is handled by re-reading the tree
again and dealing with partial copies.

Yes, sorry, forgot to mention that: hardlinks probably won't work
this way. Although backuppc handles them rather different, since
it's only rsync-the-program on one end.

Already done; makes no significant difference.

It's not for free, it's at the expense of memory on the server.
Probably not very much, but still.
Do you actually see a *problem* with it, or are you just assuming it
won't work because it seems too easy?
