Amanda doesn't track a notion of "how much space is left on the tape" - tape drives are too unreliable in this sense. Amanda also assumes that you can span from volume to volume, so getting as close as possible to the end of a volume without going over is not useful. You can affect the order in which dumps are made with the 'dumporder' parameter. At the moment, I'm working on support for spanning without partial parts, which should eliminate any loss of useful space on tapes due to internal fragmentation.

These are my taperalgo and dumporder settings. taperalgo largestfit dumporder "SSSSSS" >From amanda.conf man page largestfit The largest dump image that will fit on the current tape. In my case there were several dump image that could have been written to the tape. Amanda did not seem to pick the largest dump image that would fit on the tape.
