So if I want to persuade amanda to use more tape I should shorten the dump cycle, correct ? But I have a DDS-3 with native capacity of 12 GB and no changer. What happens if in a dump cycle there's more to be backed up than can fit on the tape e.g. if a lot happens to change on a couple of filesystems and level 1s get large ? What falls off the edge of the world ? Regards, Niall O Broin
