Indeed, it is! :-) > No spreading of Level 0's at all. Why do you say this? The 0's are *due* on Monday, in your example above. Some of them will not make it to the tape, because the tape is smaller than all the full backups, that's clear. AMANDA will find out the ones that fit on the tape, under the restriction that there will be enough space to also copy the incrementals (at least those that are very important). So, ideally, some of the full backups will be on the tape, as well as all incrementals. The rest of the fulls will be "delayed" and the planner will tell me this and I will know why this is so, but I will not worry. The next day, some of the delayed fulls will make it to the tape, along with the incrementals of that day and so on. If my dumpcycle is long enough, I will have all full backups by the end of it on *some* tape, just not only on that of any specific day, but evely scattered on all tapes. If not, either my dumpcycle is too small, or runspercycle is too small, or both, or my tapes are hopelessly underdimensioned for the task. It's as simple as that. -- Regards Chris Karakas http://www.karakas-online.de
