exchange log file drive keeps growing

If your Exchange Disk Filling Up with Log Files, the issue is likely to be one of the following:
Cause: You aren’t backing up the mailbox server using a proper Exchange Server application-aware backup product.
Cause: You’re using the wrong type of backup. Please refer to this post: Barracuda backup doesn't clear Exchange log files - http://www.chicagotech.net/exchange/exch2010-1.htm
Cause: The backup is not completing successfully. Please refer to this post: Emails stay in queue because of low space in log drive - http://chicagotech.net/netforums/viewto ... e2f56b5ad7
Cause: The backup is completing successfully but transaction logs are not truncating. Check the Application Event Log on the mailbox server for errors with the log truncation process.
