Howard,
Can you share the Exchange server physical config (cpu/mem/disk) as well
as the .cfg you use for these Exchange servers? Are they x86 Ex2003 or
x64? Did it run this well out of the box or did you need to tweak it to
reach this point? We have several Ex2003 servers, one of which has a
total of 909gb in 4 SG's and is taking 16.5hrs to do a full backup (.857
gb/min). it is gig attached, and the tsm server is using a multi-gig
trunked line. I just cant seem to squeeze any more speed out of this
backup and I would love to find out how you are doing it.
Thanks,

We have 4 Storage Groups per Node, and 3 nodes. However, 1 node is
about 600 GB, the other two add up to about 600 GB. They all backup at
the same time of the night, when they do a full backup on each box. We
have other Exchange nodes that backup at various times but these three
(being the largest) I have backing up at a time when they can have more
bandwidth. We back them up via the LAN (1 GB NICS each) directly to
disk. They all take about 4 (sometimes 5) hours each to backup unless
the LAN is congested which means the total backup time for the 1.2 TB is
around 4 to 4.5 hours, which is about 4.5 - 5 GB per Min. Which means
we're pushing the TSM Server's NIC to about the edge. :-D
The TSM server has 1, 1GB NIC (Teamed in Failover mode). Note: The 1
Largest node only takes 4 hours to do a full backup. We used to have
them in a direct to SAN backup, but discovered that doesn't work much
faster than doing the LAN backup, and has the added burden of tying up 1
or more Tape drives per node, which could be doing other things. Now,
if I had a 1.2 TB single system, this would be a no brainer for Direct
over SAN backup. But until it gets bigger than 8-9 hundred GB it really
does work out to be equal either way.
See Ya'
