End of included message Alexander, Amanda uses a different model/concept than you are trying to fit on her. First, amanda expects each run of amdump will be on its own set of tapes. This means several tapes are in a rotation known as a tape cycle. My tape cycle is 18 tapes. Amanda will NOT add one dump to the end of a tape containing a previous dump. It will either refuse to use the tape (if your config says it is not time to reuse the tape) or it will overwrite the old data with a new amdump. Having a tapecycle of 1 means the next dump always destroys the ONLY dump you currently have. A definite NO-NO :) Second, amanda does not synchronize the levels of dump of each file system with each other one. Instead, each file system is scheduled independently with an aim of keeping the total size of each amdump run consistant. So you should excpect to see a mixture of levels in each amdump run. Third, to answer your specific question, no it will not ask. That sounds like you expect an interactive session. Amanda is designed to be run automatically on a scheduled basis (like my 2 AM nightly backup). And I'm not always here at 2 AM :) Instead, each amdump run generates a report, generally emailed to the admin, saying what tape it used and what tape it expects to have available the next amdump run. If that tape is not available for the next run, amanda complains (in the email report) and tries to do what she can. A common outcome is that the new amdump get written to a disk area known as the holding disk and can later be amflush'ed to the proper tape. HTH -- Jon H.

I'am right? Third, to answer your specific question, no it will not ask. That sounds like you expect an interactive session.

Amanda increment level?
I can't understand how amanda increment level? For example --disklist- www sda1 comp-high # / www sda2 comp-user-tar # /home www sda3 comp-root # /usr www sda5 comp-user-tar # /var --- dumpcycle 7 days runspercycle 9 tapecycle 1 tapes Amanda first night made llevel 0 next night made level 1 next day some partitions stay on level 1 some begin from level 0 and rest made level 2? -- [EMAIL PROTECTED]ICQ: 41776461 2:465/207@Fidonet Alexander Belik http://www.vnet.dn.ua[EMAIL PROTECTED]

In general, amanda will try to make sure you get: 1) At least one level 0 every dumpcycle days. 2) At least two level 0's over tapecycle tapes (so that if a single tape fails there is another level 0, even if it might be a little old). 3) Incrementals (level 1-9) will be used as convenient; the levels will increase if that is necessary to achieve 1) and 2). You've given amanda an unconventional configuration. You're telling it: dumpcycle 7 days Give me at least one level 0 on each disklist entry every 7 days (this part is conventional). runspercycle 9 Over that 7 days, I intend to run amdump 9 times. That part is unconventional. But if I wont to run 7 times in 7 days? This is conditional? The usual use for runspercycle != dumpcycle would be something like dumpcycle=7, runspercycle=5 (e.g, I want a level 0 every week, but I'm only going to run amdump on Monday-Friday, not Saturday or Sunday). tapecycle 1 tapes No, no, no. tapecycle is the total number of tapes you want in your rotation. For example, if your amanda runs all fit on a single tape and you run amdump 7 days/week, then: dumpcycle 7 days tapecycle 14 tapes You label 14 tapes, you always carry at least two level 0's. :) Will Amanda ask me for a new type when new dumpcycle begin? Or I must do it manualy? -- [EMAIL PROTECTED]ICQ: 41776461 2:465/207@Fidonet Alexander Belik http://www.vnet.dn.ua[EMAIL PROTECTED]
