Related questions for those in the know. - What happens if I keep introducing "new" tapes beyond the quantity specified by tapecycle? I would expect amanda will happily use the additional tapes. - Once I have lots of tapes beyond tapecycle, will amanda then accept any "out of order" tape as long as it is has not been used in tapecycle number of tapes? I'm hoping yes. Or must they continue to be used in the same order they were initially used? If the answers are those I "expect and hope", then you might try a scheme like this. Assuming 8 tapes per dumpcycle. 13 sets in yearly storage (13 x 4 wks = 52 wks, not 12 months), 1 set in use, 1 most recent held locally, and 6 sets in 8 wk storage (I up'ed it to account for yearly storage). That is 21 total sets of tapes, or 168. But only 8 sets are really cycling. So set the tapecycle to 64. (maybe lower) For three out of every 4 weeks, take one set to and retreive one set from 8 week storage. The retreived tapes will fall naturally within the 64 tape tapecycle. One of every 4 weeks, take one set to and retreive one set from yearly storage. They will certainly be beyond the most recent 64 and will "I hope" be accepted. Now, what happens to the index during all this I haven't a clue. Do people do all these weird things with commercial backup software? -- Jon H.
