transaction log

Not open for further replies.


I just transition our environment from exchange 2003 to exchange 2010 server and noticed that my transaction log are increasing fast. What is the best practice for dealing with transaction files. Should I enable circular logging?
Thanks in advance,



Best practice is to do regular backups, using an Exchange-aware backup solution so that the logs get truncated.[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "


Agree with mjolinor about using Exchange aware backups as your primary solution. If you can't do this, then it is safe to enable circular logging. Note that with circular logging, you will only be able to restore at the moment in time the backup took place (instead of being able to replay log files after a database restore)

Can you define "fast"?

How did you deal with the logs in Exchange 2003? :)

Just a though,

If you've just moved all your mailboxes from Exchange 2003, that may explain the unexpected log file growth during the mailbox moves.

As suggested above, if you require some sort of recoverability should something happen to the server or database, you should strongly consider Exchange-aware backups, or look into what native data protection in Exchange 2010 can offer.
