thanks for this information - this is very helpful

In other backup systems I've used, I have always kept certain level 0's
out of the rotation so's that I could alway go back quite a bit if
necessary.

Can I add as many new ones as I want then? At the moment the
configuration is like this:
dumpcycle 4 weeks # the number of days in the normal dump cycle
runspercycle 20 # the number of amdump runs in dumpcycle days
# (4 weeks * 5 amdump runs per week -- just weekdays)
tapecycle 40 tapes # the number of tapes in rotation
# 4 weeks (dumpcycle) times 5 tapes per week
I didn't set these; the previous administrator did.
And yet there are over 100 tapes in the tapelist file!
Do these figures mean that a level 0 must be done on each file system
at least once every 4 weeks?
And I guess if all the tapes are being reused then these backups are
just for emergencies and if you wanted to look at something from say 3
years ago, you couldn't.
I guess what I'm saying is: I think it would be a good idea to keep all
the tapes in the tapelist for recycling but on top of this Iwould like
to do a one-off level 0 of everything and keep that aside.
Is there an easy way to do this?
Thanks agian for your help on this.
