Exchange transaction logs growing quickly

Hi

We are running Exchange 2007 SP2 with CCR. Today, we had an issue where the transaction logs were growing very quickly. I was worried we'd run out of space on the drive! Luckily, that stopped and they went back to normal. We ran a full backup and the problem didn't re-occur.

In case this happens again, I had some questoins:

1. Is there anyway to check which mailbox is causing the transaction log growth?

2. If the logs do grow and it looks like we're going to run out of space, what's the best thing to do?

3. Does Exchange 2007 have the same checkpoint depth as 2003?

How much space do you have for logs?   Your backup jobs should be clearning these.

The simple thing to do is move the logs to a drive that has no storage space limits, it possible.  Alternatively, you should enable circular logging which allows Exchange to overwrite the log files.

Keep in mind that it is not 'best practice" to enable circular logging, though it will work

Thanks everyone

But to move the logs we need to dismount the store don't we? I don't want to affect users.

no one said anything about moving the log file location.  Circular logging simply deletes them as they are committed.

We take a full backup every night. Normally this works fine. Except today the logs were growing very fast, hence the question on finding out what caused it.

JDtuck mentioned moving the logs?

Ahh yes, sorry he did suggest moving the logs.   Short term answer, enable circular logging.  

Look at your logs, make sure they only date back to last nights backup.  If they go farther back, then figure out why they are not being removed.

Long term... if you are filling up your drive with logs after less than 24 hours since your last full backup, then you need to expand the size of the drive which the logs are on.
