I am also thinking about the same setup (Full after a half year for  
ten years).

I am just curious why "Run = Level=Full jan jun 1st sun at 8:15"
would become complicated?


Furthermore i thought about putting one Full backup at one Volume(set).
I am not sure if "Maximum Volume Jobs = 1" would accomplishing this.
Because the data could grow and needing a second tape. Or how to delete
the appendable flag of the volume? I read something about that but
can't remember where :-)

Thanks

PM
