My idea was to remove the Full (and Diff) from the schedule. Have in the
schedule only Incremental backups everyday. Then set the Max Full
Interval to 30 and the Max Diff Interval to 7.

In this way the daily Incremental would be upgraded to Diff or Full only
at the appropriate time. Does it make sense?

I see. It's in the "New Features in 3", but not in the documentation for
the director. I missed it. Thanks.
