I am infrequently getting tape full conditions at times when I did not expect it. My tapes are DDS-4 tapes and they are considered "Full" by bacula at various capacities, for exampel:

21,112,841,569
  6,445,884,582
17,477,850,063
15,855,178,172

After the last volume ran "full" and mounting of the next empty volume it appended only 3,710,244,549 to it, an amount which I had thought could easily be squeezed into the "full" volume.

I don't understand what triggers the "Full" condition especially the 6GB volume is wierd since it shouldn't be full before approx. 20GB of data has been written to it.

I am trying to optimize the use of the tapes but this process is difficult to carry out when bacula determines the full condition at such different times. Are there anything I can do to ensure that the full condition becomes close to 20GB or do I have to live with this strange phenomenon?

Are you using hardware compression?

No, s/w compression. Do you recommend that I use h/w?
