I got that when the full started again. I think I'm getting it now on how to schedule this.
What I've done is create 4 scripts to enable and disable the weekly and monthly jobs. So for instance, my full backup runs on a Sunday at noon, and he monthly is on the last Sunday of each month.
I've created 3 Media Pools Daily, Weekly and Monthly. Created two jobs Weekly and Monthly, each with Incremental backup enabled and using the Daily Media Pool. On the first Sunday of each month, I have a scheduled task to enable weekly tape job, and then another to disable the monthly tape job. The weekly runs until the last Sunday, when the monthly job is enabled, and weekly is disabled. Full runs on the last Sunday, and I leave the monthly job enabled for a week, writing the incremental jobs to the Daily Media Pool, that way I don't duplicate the full backup.
Does that make more sense?
