I'm not sure I'd agree. I suppose that the internal handling of mails is
much simpler and faster if every mail resides within a single database.

After more than seven years of using PowerMail, it appears that I'm not
likely to hit the 2 GB within the next decade at least, but maybe I am
an exception. Anyway, even if the mail database was split into several
databases, you could still run against the 2 GB limit. Wouldn't lifting
the 2 GB limit be a more straight-forward remedy?

With a couple of databases, it would be just the same -- unless some
folders were rarely used and thus wouldn't need to be saved with each
backup. Unfortunately, folders whose content rarely changes typically
contain a relatively small number of mails (for just that reason), so
even when these folders weren't included in every backup, the disk space
saved would be negligible. With my setup, most folders receive mails all
the time, so it wouldn't make much of a difference anyway. However, the
problem Time Machine has with big files that are frequently changed is a
general one, and not just for database files; virtual volumes for
example are suffering from the same problem. Even Apple's Aperture is
affected. This problem isn't likely to go away, so I would say it is up
to Apple to provide a solution. Maybe Apple hadn't thought of this when
designing Time Machine, but eventually, they will have to.
