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. > > runspercycle 1 > > amanda runs 1 times in the dumpcycle. Means: amanda thinks you start > only one backup run in a week. This is probably not what you want. 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. > > tapecycle 2 > > amanda knows about 2 available tapes at all. > > > runtapes 1 > > amanda will use max. 1 tape once per run. > > > and changer.conf has: > > > > firstslot=1 > > lastslot=5 > > driveslot=0 > > havereader=1 > > > > Should I change dumpcycle back to 0 and tapecycle to 1 or what? > > What you want may differ, i haven't followed this thread from > beginning.

I have 5 tapes so I will set tapecycle to 5. > If you run amanda five times a week, set runspercycle 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. > If all backup data for one run fits to one tape, leave runtapes at 1, > but it doesn't matter if you set it to 2. amanda will not use the > second tape for a run, if all data fits onto one tape. 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. > However, it takes some experimenting and some weeks of manual > monitoring to learn and see how amanda works. 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. Regards, Hugh -- Hugh E Cruickshank, Forward Software, www.forward-software.com
