Should I Backup Mailstores individually? - 4.Feb.2009 5:36:30 AM

Hi,

after running a single mailstore for a long time, it got up to 100GB and basically filled the 'database' drive.  I've increased the storage capacity, and I'm about to create a second extra mailstore (giving three altogether) to split the mailboxes over.
The question is simply, should I backup each mailstore individually, or just continue to backup the whole information store in one go as I do currently?
I just use NTBackup for backing up exchange.
Just interested if there'd be any performance, reliability or size benefits to go through the effort of creating and scheduling three seperate backup jobs rather than just running with the existing one.

thanks for any help.

Let NTBackup handle the entire Information Store.  There isn't any advantage in separating the backups unless you need to archive them separately (e.g. different locations).

Do you have 3 Storage Groups or Single Storage Group with 3 mailbox databases ?

Hi ,
I have a question,where do you have your transaction log files is that in the same drive where you have your database or is it in a different drive.
If its in a different drive you can avoid bottle necks in other words performance issues.
Also would like to know if you have performed offline defrag any time.

Thanks

Thanks for the replies!
Firstly, i like the idea of sticking with the single backup.

Secondly, it's a single storage group with 3 mailbox databases (and 1 small public folder database).

And for the third question, I have done offline defrag in the past, and will be doing it again (hopefully this weekend) on the original mailbox store once i've moved lots of the mailboxes into the other stores.  And hopefully when i have three smaller mailstores it will make it easier for me to schedule more regular defrags of the mailstores, as obviously there's quite a bit of downtime doing it with a 100GB store.

Since you have available Mailbox Stores, you should move all the mailboxes out of the 100GB store.  That will effectively create defragged stores and afterwards you can simply delete the original store.  This will keep your mailboxes online all the time (except while the individual mailboxes are being moved).

Don't run the offline defrag unless you are trying to resolve a specific problem (reclaiming disk space doesn't really fall into that category).

sounds like a good idea!  will there be no issues with deleting the default mailstore, as obviously it's the original created one that would be deleted?

None.  When it's emptied of live mailboxes, dismount it, delete it, then delete the database files (EDB and STM).
