2003 Information Store Backup Slow
1) I checked and there is no
tracker.exe running.
2) There is no AV running on it.
Checked event logs and only found entries
about backing up specific files under the information store.
Network speed?!? They are SAN MEDIA
Servers, and backup directly to the SSO drives.
Yes the policy is configured to use the
storage unit for the media server.
Seeing your backup time does not sound
positive to me.
75GB in 47 mins, means taking my 805GB
divide by 75GB = 10.72 hours!

2003 Information Store Backup Slow
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.
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!)

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?
