after more searching in my outbox than I had thought would be necessary, let
me quote two past messages where I tried to explain this:

(you might also want to look at the rest of the threads quoted).

That's its job, and that's what it will do. Note, again, that "incremental
backup" means "faster, but possibly slightly less accurate".

Necessarily. In the backup from today, you won't find the file, whereas in the
backup from yesterday, it will still be there.

3.1.0 config.pl:
