Hi, MacMedix.

Your partitioning strategy seems reasonable.

I wouldn't use DMGs for the other backups: as you said, a sparse image would be more reasonable. The FAQ has data about how to use them -- see "How do I update an image?" there for more.

You will need to edit the Daily Backup script, change the settings in there, and save it (as an application) with a different name for each volume. I believe the 1.5.5 script deals with a SuperDuper! that's busy, so that shouldn't be a problem.

This'll all get a lot easier in v2.0, too...

Hope that helps!
