Yes - I actually posted a config from a couple of test setups i created a
while ago and looking again i see it doesn't look right -

Just checking one of my configs from a production system i have..

dumpcycle 1 weeks       # the number of days in the normal dump cycle
runspercycle 7          # the number of amdump runs in dumpcycle days
                        # (4 weeks * 5 amdump runs per week -- just
weekdays)
tapecycle 21 tapes      # the number of tapes in rotation

which looks much better to me - i think!!

thanks

Tom
