Hi
Well my Ex2k3 is a SAN Media - get approx 60 - 80GB+ - I backup
the information store policy and it uses one
drive.
You can use the * at the end to stream the stores (which sounds
like the route veritas has made).
To give you an idea, checking last nights backup took 47
mins to backup 75GB
I
use SSO/SAN/Fiber/LTO3 HP ESL Library.
Two things to look at:
1) Make sure tracker.exe is not running locally on the Exchange
box (Start, Run, type MSCONFIG and goto the STARTUP
tab)
2) Turn off any AV for the Windows operating system (do not turn
off Exchange AV)
Any errors in the event logs? Almost sounds like Network speeds to
me.
your policy is configured to use the storage unit for the Media
Server?
Hope this helps (a little!)

All,
I have 2 Exchange 2003 servers, both running Server
2003 SP2. I will have to admit I don't know much about the 2003 exchange
setup, but I was told that they are on the latest patches for Exchange.
Both servers are SAN Media servers and backup to a tape drive via SSO.
The Silo is a L700E with 9940B tape drives. The Disk space is actually
EMC drives via a Disk SAN. The backup is a Full backup every
night.
Here is the issue… the backup doesn't run very fast
at least I don't think so.
Six months ago, we had Veritas come in and look at
them and help speed them up. We did 2 things; One we set limits on
the mailboxes of people so the overall size of the information stores when
down from 1.2TB to 705GB. Two, we changed the backups to backup each of
the 4 information stores at the same time and multiplex them.
1st Exchange Server: (Total 81.4GB per
hour) SG1
Mail 20.3GB per
hour SG2
Mail 20.5GB per
hour SG3
Mail 20.1GB per
hour SG4 Public
Folder 20.5GB per hour
2nd Exchange Server: (Total 82.6GB per hour)
SG1 Mail
19.5GB per hour SG2 Mail
19.9GB per hour SG3 Mail
19.4GB per hour SG4 Mail
23.8GB per hour
Since that translates to about 22.5MB per second on
tape drives that should be able to do about 60MB. I have a couple
Windows 2003 server backups over the network that are doing 35MB per
second!
So, does anybody get about the same performance?
Better? Any ideas about things to look at?
