Heim, 608-263-4189, jh...@math.wisc.edu I think you are saying don't DON'T want bumping. Bumping is going down to a level-2 backup from a level-1, so as to reduce the amount of data being saved. I think you are saying you only want level 0 backups done. I do this for my "archival" tapes, which should not contain level-1 backups and thus be reliant on some other tape. I use these settings: dumpcycle 0 # the number of days in the normal ARCHIVE cycle tapecycle 9000 tapes # some infinite number; always fresh tape for archives inside my dumptype's I include: define dumptype dailyNormal { BDnormal #read in the other file strategy noinc #nothing but full backups; don't even calculate other sizes skip-incr yes } Am I hearing you correctly?
