Hi All, Is there any way to identify what could be the root cause of this problem and how to rectify this to prevent the disk getting full ? I'm having problem in one of the partition of the Exchange Server 2007 SP 2 transaction log, it is installed on my Windows Server 2008 with the configuration as CCR. in one of the storage group, the transaction log partition goes drastically low (from 30 GB into 0 KB in just over the weekend period) when the backup missed just one day thus rendering the whole mailbox on that Storage group inaccessible. Any comments and suggestion would be greatly appreciated. Thanks./* Server Support Specialist */

Thanks James, I wonder what could make the log file grows large in short period of time./* Server Support Specialist */

The only 3rd party is just Symantec Anti Virus and the Symantec Backup software./* Server Support Specialist */
