Hmmm, I'm using the latest 2.4.5 snapshot, with the taperalgo set to
largestfit, and this:
dumporder "STTT" # specify the priority order of each dumper
# s -> smallest size
# S -> biggest size
# t -> smallest time
# T -> biggest time
# b -> smallest bandwidth
# B -> biggest bandwidth
# try "BTBTBTBTBTBT" if you are not holding
# disk constrained
# BUT, if you want streaming, start with the
# big ones and work down
And a typical backup session will start with the largest and work down, like
this:

And thats a puzzling ls -l of one of my virtual tapes, note
the time stamp on the last 2 items, which should have been
