Hi,
Run 'amstatus <config>', it will tell you why it don't start new dump in
parallel.

Dear reader,
I am using VERSION="Amanda-2.4.4p2" on a LINUX 2.6.5 with LTO-3 tapes. In
general the performance is great, but on every forced, complete backup, the
procedure takes almost 24 hours.
I have to backup about 700 GB uncompressed, and supply the system with about
580 GB holding storage. The system starts with the requested 5 dumpers, but
utilizes only 3, from which the third only works once. The others work along
but never use more than about 25% of the available holding disk space. No
error messages or other complaints.
from my amanda.conf

weekdays)
