I just looked at the wiki, since I toughed this out without it. Some notes on the wiki:

For better documentation, zmschedulebackup --help is (at this point) better documentation.
Using the -R option to replace your schedule, you can specify all the schedules (delete, incremental and full) in the same command:
Since there was no reference on the "d" (delete) schedule, you'll notice that it requires two parameters -- one for the age, and one for the crontab schedule. I hope this helps. It took me a handful of attempts before I figured this tool out. The --help option helped a lot more than either the admin guide or the wiki.
