Hi Jean-Louis,

I had hoped that the list of possible suffixes (per http:// wiki.zmanda.com/index.php/Amanda.conf ) could be interpreted to mean that I could tell Amanda to have a dumpcycle of 4 tapes as opposed to days. Since you are telling me that that won't work, can I deduce from that that I can not test out a dumpcycle of 5 days by running amdump five times in a row (since that will be all on the same day)?

Could it be considered a great feature if dumpcycle could be given in units of tapes?

Thanks,
René

dumcycle is a number of days? you set it to 4 days.
The scheduler work in days, not in number of tapes or run.

Hi,

I am trying to set up my test system so that I get on 5 tapes 2 full backups at any time and incremental ones in between them. I thought that I should be able to do that using in my amanda.conf these lines:
dumpcycle 4 tapes
runspercycle 4
tapecycle 5
usetimestamps true   # make sure I can do more than one test a day

when I run an amdump on this test (all on the same day, since I am not patient) five times in a row, I end up with no level 0 dumps (since they got overwritten).

I assumed that by setting the dumpcycle to 4 tapes, I should always have a full dump every fourth tape and with having a total of 5 tapes, I'd end up with two level 0 dumps on all my tapes together.

Am I doing something wrong in the conf file, or is it not possible to test amdump several times on the same day to try to speed up the testing of a longer dump cycle?

Thanks,
René
