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!)

Subject: [Veritas-bu] Exchange 2003 Information Store Backup Slow
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?
