Question 1. What is the LONGEST interval between level 0's you want?
Right now you are saying 6 weeks. Getting more than 1 every
6 weeks is not certain. Only that you will get at least 1.
Setting dumpcycle to 4 weeks only makes certain you get
at least 1 every 4 weeks.
Set it to 1 week and you will get at least 1 every week.
Question 2. How frequently do you run amdump? It appears to be 5 times a week.
You should set runspercycle to the number of amdump runs per dump
cycle. If you set dumpcycle to 2 weeks and do 5 dumps per week,
runspercycle should be 10.
The number of tapes does not affect the other parameters. But it should be
greater than runspercycle. Usually by a factor of 2 or 3 or 4 or... depending
on how many cycles you wish to keep in case of problems.
