thanks again :-)

here my updated config  :
inparallel 8
netusage  30000
maxdumps 10

maxdumps 1 is normal, you may increase maxdumps if you have
a very powerful box.



dumporder TTTTTTTT


I read about dump at :
http://dump.sourceforge.net/isdumpdeprecated.html
so I'll try it again.

last question ... for new ;-), what do you mean by :
 "set the correct "splindle" for each DLE"

A disklist entry can have as 4th parameter a number, indicating
on which disk the DLE is on. Amanda will not schedule another dump
on the same disk.  This avoids heavy arm movements and slowdown
of disk and dump or estimate.

When having maxdumps set to 1, you won't notice this, but
when allowing more dumps on one host (maxdump > 1), you should
make sure that you have asigned spindle numbers.

Like this:

the.host.tv   /disk1/dir1  comp-user-tar  1
the.host.tv   /disk1/dir2  comp-user-tar  1
the.host.tv   /disk2/dir1  comp-user-tar  2

The first two entries have the same  spindle number: amanda will
not start dumps for the second when the first is still busy.
When having maxdumps set to 2, amanda may schedule a dump for the
third disk at the same time as one of the other two.
