If you count the two-week period from the mtime of the file, then
backups of really old files will be deleted as soon as they are saved.
I think it would make more sense to count from the time the backup file
is saved. To do that, use a separate --backup-dir each day (e.g.,
--backup-dir=../backups/$(date +%Y-%m-%d) ) and simply delete each
backup dir as a whole when it becomes two weeks old.

The only disadvantage is that with multiple backup dirs, it becomes less
trivial to find backups of a particular path, but it would be easy to
write a script to help with this.
