We are running Exchange 5.5 on a box running Win2k Sp2, 1.1 GHz
x2 with 2.6 gig ram, TSM version 5.1.5.2, and TDP version 5.1.5.0.  It's
talking a TSM server running 5.1.6.

            The backups are normally ran via a batch file using the command
line program with the switches we want, " tdpexcc backup * full
/tsmoptfile=dsm.opt /logfile=excsch.log >> excfull.log". All paths are
correct.

            The log is telling me that it runs for about 10 hours each night
and will send a total of 35 gig. We looked at various things, network, CPU
usage, etc. The scheduled backup is ran after 5 PM when most of the users
are gone for the day.

We have watched the CPU usage during the day and with just normal activity
the usage was 5-10 %. After the backup was started it jumped to 10-20 % with
occasional bumps to 80 %. Still not breaking too much of a sweat though.

            Then just for the heck of it we ran the same backup via the GUI
(tdpexc.exe) and it finished in less than an hour. Same file size, same
everything else.

            We watched the incoming bandwidth on the backup server and when
we ran the backup via the GUI it was almost exactly 10 times faster than
when we ran it via the command line.

            In both cases, the full backups were ran during the day with all
users online and the backup server itself doing nothing else.

            Is something going on here that we are missing?
