Created: 01 Sep 2010 | 21 comments
Hello all,
We are having a problem that i would like some help with.
We are backing up our store and our individual mailboxes by using BE 12.5 to disk.
The file backups preform verry wel, but our exchange backup is not it is terrible we are getting speeds up to 60mb/min.
So my time widow for backups is getting messed up.
When i am not doing a GRT its realy fast but when i use GRT( because we want to do mailbox backup as wel ) it goes realy slow as i said befor.
I have been looking on the internet for a solution and i tried almost everything now.
So i am getting a litlle dessperade right now, can any body please help me out?
Greetings

1st thing to check make sure
1st thing to check make sure you are not backup individual mailboxes using the brick level backup .
You can check that by going to the backup job properties and make sure Exchange mailboxes are not selected .The only thing which need to be selected is the information store . The backup job runs extremly slow when you run a brick level backup as it uses MAPI.
Just disable the legacy support by going to Tools--Option --Ms Exhcange -- Uncheck the legacy support option here
Using the GRt technology you just need to backup Information store which will all you to restore individual mailboxes .
Hope this helps

Thanks for the answer i am trying it right now, i had brick level backup indeed enabled.
So in my selection i only selected the First storage group and not the mailboxes and the Public Folder Database.
And in the options i unchecked the legacy support option, and left the GRT option on.
I hope this works:)

We are running Kaspersky
We are running Kaspersky Security 6.0 for Microsoft Exchange Server 2007
Have you tried to disable it
Have you tried to disable it completely during a GRT backup, or can you disable "on access scanning" in Kaspersky for Exchange ?
Just for testing, to see if it makes a difference.
