Offline backup/Circular Logging Disabled/Transaction Logs

I am in the planning stages of performing an offline backup and defrag. I am going through the steps of KB article 296788 http://support.microsoft.com/?kbid=296788, step 5 of the offline backup states that if you have circular logging disabled you should backup the numbered transaction logs.

Can I do a full backup prior that would flush the transaction logs, and not have to do this step? Of course I would verifying that there no transaction logs after the full backup.

Exchange 2000 SP4
Veritas 10.1

Thank you,
Tricia

Tricia,

To answer your question, yes, if you do a full online backup then all the transactions should be truncated and you wouldn't need to backup the transaction logs during the offline backup.  If you're looking to do this just so you can perform a defrag of the database, then I would suggest if you haven't used all your mailbox stores yet that you create a new mailbox store within the same storage group and just move all the users to the new store, then you wouldn't need to defrag the database at all.  However, if you still desire to do the defrag or can't create a new store, then when you stop the MS Exchange Info Store service all the transactions get committed and you don't need the logs anymore after that.  All you would need to do is just back up the info store (both the *.edb & *.stm files) before starting your defrag.

Hope this helps!
Bobby
