You can configure bpdbjobs via bp.conf entries to include DEDUPRATIO, which might help.
First, here are the bp.conf entries which will recreate the "default" output from a bpdbjobs command (at least, on my 7.5.0.5 test system):
BPDBJOBS_COLDEFS = JOBID 5 true
BPDBJOBS_COLDEFS = TYPE 4 true
BPDBJOBS_COLDEFS = STATE 5 true
BPDBJOBS_COLDEFS = STATUS 6 true
BPDBJOBS_COLDEFS = POLICY 6 true
BPDBJOBS_COLDEFS = SCHEDULE 8 true
BPDBJOBS_COLDEFS = CLIENT 6 true
BPDBJOBS_COLDEFS = DSTMEDIA_SERVER 12 true
BPDBJOBS_COLDEFS = ACTPID 10 true
BPDBJOBS_COLDEFS = FATPIPE 7 true
To this, you might want to add these lines:
BPDBJOBS_COLDEFS = KILOBYES 9 true
BPDBJOBS_COLDEFS = DEDUPRATIO 12 true
A complete* list of options for BPDBJOBS_COLDEFS can be found in the Admin Guide I in the tables in the section on pages 231-235:
...or in this standalone TechNote:
*well, I SAY complete, but I have no idea what FATPIPE means or what it represents...and it isn't in the list. Oh well!
For additional info, here's some more reference material: the Commands Guide man page for bpdbjobs AND the Commands Guide itself:
Hope this helps!
