Do frequent Full Backups Move only the # of users between backups that the Log drive has space for.

I just verified that the log files are being written to the drive I thought they were. The processor is barely being used on the box so compression wouldn't be bad.

Moving large mailboxes creates a lot of transaction logs. You might want to consider increasing the amount of space you have allocated for the transaction logs temporarily while you're doing the mailbox moves, then cut it back when you're finished. Transaction logs also compress pretty well, so you might consider enabling compression on the transaction log directories if you can afford the processor load without it hurting your performance too much. ________________________________ From: Karsten, Matthew [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 29, 2008 12:59 PM To: MS-Exchange Admin Issues Subject: Moving Mailboxes Exchange Server 2003 SP2. We have always had all of our users (around 1200) in one large store. This single store had grown to be around 400GB. A while ago we decided to start moving all of our users out of this store and into several different stores organized based on desired configuration. We then began moving mailboxes out of the large store in groups into the other stores. This has been going fine for our smaller users. We now have hit a point where we are at our users that have larger mailboxes (200mb - 2gb). As I am moving them in groups, the stores keep dismounting. Looking at the event logs it appears that they are dismounting because the logs are filling up. I did more looking and it appears that the easiest way to fix this is to enable circular logging. Reading more on circular logging, there seem to be mixed opinions on whether it should be enabled or not. So I guess I have 2 questions. 1. Is circular logging the way to go to deal with this? 2. If so, is there anything I need to watch out for? I had been planning just to enable it to finish the mailbox moves and then just turn it off.
