I believe that I understand this but what I do not understand is that
while I specified "--dumpcycle 0" on the amservconfig command the
resulting amanda.conf file has "dumpcycle 1 week". I specified "0"
because I would like each tape to be a level 0 backup.

If my dumpcycle was 1 week then you would be correct. However as far
as I can see I actually want a dumpcycle of 1 day (one weekday) and
then only one run per day. If that is the case then I think that the
runspercycle would be correct.

That is one of the reason I restated what I was trying to do.

I have 5 tapes so I will set tapecycle to 5.

Since I actually want a daily level 0 backup I suspect that I should
set dumpcycle back to 0 and runspercycle to 1.

All the data does fit on one tape and there is tons of room to spare
for the foreseeable future so I will leave runtapes at 1.

This I understand and I am fully prepared to make the necessary efforts
however I am an old dog and it takes longer for me to learn new tricks.
Thanks again to everyone who has responded so far. It has been greatly
appreciated.
