It's difficult to control that precisely. Two main things affect it. How frequently your automatic backups happen and how long you told DD to keep backups.

By default, with weekly backups and keeping them forever, DD will make a fresh backup every three months.

If you change it to daily backups, I believe it switches to monthly fresh backups.

It sounds like you already make regular manual backups. I'd say change the automatic backup setting to weekly and continue with your manual backups. DD should use three month intervals.

In Ubuntu 12.10, DD will always use three months no matter what. Though you can fiddle with a secret config key to change it if you really want to.
