You will get a full dump of each entry in the disklist at least once 
a week, mixed in with incrementals in a schedule that try's to 
equalize the tape useage per day.

But with only 7 tapes, there is a possibility of over-writing the 
last full of that disklist entry with only an incremental as amanda 
gets the scheduling adjusted.  No one here would recommend only 7 
tapes, the murphy style disaster is inevitable...

You need at least 14, and I have 20 in my own rotation, so I'm 
always assured that there are at least 2 fulls available in the 
unlikely event a disk goes belly up on me.

Not without manually forceing the schedule, which is, generally 
speaking, not always a good thing(tm).
