You will get a full dump of each entry in the disklist at least once a week, mixed in with incrementals in a schedule that try's to equalize the tape useage per day. But with only 7 tapes, there is a possibility of over-writing the last full of that disklist entry with only an incremental as amanda gets the scheduling adjusted. No one here would recommend only 7 tapes, the murphy style disaster is inevitable... You need at least 14, and I have 20 in my own rotation, so I'm always assured that there are at least 2 fulls available in the unlikely event a disk goes belly up on me. >What will be the formula to work on here? >dumpcycle= period between full dumps? >runspercycle= number of times backups will be done(divided into > dumpcylce) tapecycle=number of tapes used in dumpcycle. > >If I have dumpcycle=1 week and runspercycle=5 and tapecycle=5 >Will I then get 1 full dump per week and incrementals monday to > friday ? Not without manually forceing the schedule, which is, generally speaking, not always a good thing(tm). >Sorry for this all but I am writing a newbie howto and need to get > my facts straight. > > >Mozzi -- Cheers, Gene AMD K6-III@500mhz 320M Athlon1600XP@1400mhz 512M 99.14% setiathome rank, not too shabby for a WV hillbilly
