Re: amanda-users list problem
[EMAIL PROTECTED]: That got brought to my attention today, but unfortunately, my tape cycle is only eight days, so the last good backup of the file was erased quite some time ago. I've seen others near me have this sort of problem, and I've only narrowly avoided it myself. This need to notice/restore before the tape cycle runs out is a recurring theme in amanda usage. Partly to avoid this problem, I write an extra set of tapes periodically. Amanda's automatic balancing wins big in normal operation, but is a bit problematic for the straightforward notion of grabbing a week's tapes for archives. (If runspercycle is 5, you can't assume a set of 5 tapes has a full dump of every fs.) I avoid this behavior for the 'archive' runs by setting dumpcycle to a few weeks. Then if I did a set of archive tapes (onto fresh tapes) once a month, all dumps will be late and the tapes get filled up. Basically, I keep going until there are no more deferred dumps. This works pretty well, but it feels too manual. Another strategy would be to have three tapecycle's worth of tapes, and swap them out every month or so. One feature that might be nice would be to have the compression rate estimates be separate from the log of dumps, so that two configurations could share them. Right now I manually move them over with export/import. Another feature would be to flush to the tape at the beginning of a dump run, and then do more dumps to fill the tape. That way when the compression estimate is off and the last dump doesn't fit, you can move forward without either redoing the dump or only using part of a tape. Using a strategy of biggest dump first would help, too; I think that would lead to the greatest likelihood of using more tape. (Speed doesn't bother me too much on these, usually.) Any other ideas for how to address this issue with Amanda in the current form, or other suggestions? Greg Troxel <[EMAIL PROTECTED]>
amanda-users list problem
Around October 30, 2001, the system housing amanda-users crashed. When it was resurrected, the file with the amanda-users list in it had zeroed out and I did not notice. That got brought to my attention today, but unfortunately, my tape cycle is only eight days, so the last good backup of the file was erased quite some time ago. As a result, I've taken the list from the way it was back when it was hosted at cs.umd.edu in 9/1998, and applied all the changes that majordomo had logged since then. In theory, this means that the list is exactly how it should be, but reality may be different. Should you have been inadvertently placed back on to the list, you can unsubscribe by sending a message containing 'subscribe amanda-users' or 'unsubscribe amanda-users' to [EMAIL PROTECTED] If you have any problems with unsubscribing or otherwise with the list, please direct them at [EMAIL PROTECTED] amanda-hackers and amanda-announce were unaffected. Needless to say, anyone who sent a message in November may want to consider re-sending it... -Todd (Amanda Core Team)
