Of course there are other ways to do things, but they aren't
necessarily going to be better.  I'm not convinced that there
is much you can do to maintain any kind of structured order
over a long term when you are adding files from multiple
sources simultaneously and expiring them more or less randomly.
You might make it faster to traverse the directory of one
host or the pool, but in my usage those are rare operations.
You could also make it easier to do normal file-based copies
of an existing archive/pool, but there are other approaches
to this too.

Rsync incrementals turn on the option to skip files where the length
and timestamp match, making them considerably faster but more likely
to accidentally miss a changed file. However, since they always work
against the last full, you end up re-copying things that were copied
in previous incrementals.  There is some room for improvement here.
