I asked Gene for hise amanda.conf entries, which are: dumpcycle 1 week runspercycle 7 tapecycle 20 Using this configuration, I understand amanda will schedule a level 0 each week (dumpcycle). At any one time, you would have 3 level 0 dumps (in case of tape error, or a dump could not be restored). So tapecycle does not need to be a multiple of dumpcycle or runspercycle? It's not quite clear what amanda.conf recommends the "extra" tapes in the tapecycle are for--after amanda has been through one cycle of the tapes, there are really no more "extra" tapes?? amanda.conf: tapecycle 19 tapes # the number of tapes in rotation # 4 weeks (dumpcycle) times 5 tapes per week (just # the weekdays) plus a few to handle errors that # need amflush and so we do not overwrite the full # backups performed at the beginning of the previous # cycle TIA<Anne Hammond University of Colorado at Boulder
