With tape sizes what they are now I'm finally at the point where I have way more tape than stuff to back up. To satisfy my inherent laziness, I'd like to actually fill every tape (or at least come close to filling them). And then just leave my library full of tapes without ever needing to change them out.
My understanding is that Amanda has no way to append to tapes; once it has started writing to a tape, that tape won't be used again until the next pass through the tapecycle. That implies that you must keep backups on the holding disk and write them only when you'll have a nearly-full tape. I have plenty of holding disk (at least until I move to LTO8) so that isn't an issue. Currently I have these in amanda.conf: tapecycle 47 tapes autoflush yes taperflush 70 flush-threshold-dumped 70 flush-threshold-scheduled 90 Is that basically all I'm supposed to do? Because according to the reports, each tape is only getting about 50% full. So I think I must be missing something about how those four flush-related parameters interact. - J<
