Hi all, I still have not found a reliable solution.
Let summarize again what I want tho achieve: - 3 generations backup on USB disk - change the USB disk from time to time So I defined the 3 pools for each generation and labeled the a separated set of media on 2 disks: disk1: d1foof1, d1foof2, d1food1, d1food2, d1food3, d1food4, d1fooi1, d1fooi2 disk2: d2foof1, d2foof2, d2food1, d2food2, d2food3, d2food4, d2fooi1, d2fooi2 Each disk works fine for itself. But if I swap the disks bacule creates the volumes of the removed disk for the next backups. The file device is defined with removeable-media=yes. I tried "update pool". I do not want to disable and enable all volumes one by one manually. How could I do it in a bunch? Is there an example of a script? But most propably it is simply a question of configuration. Please give me a hint. It would be perfect if after a disk change bacula would use the media available on the new disk and start with a full backup.
