Hi Experts, We have an Exchange 2007 Environment with 2 sites. Site1 is having 8 Mailbox servers and Site B is the DR of Site A with SCR configured. We use HP DP for backups. From a month we have problems with Full and incremental backup, they are failing and even if they succeed getting errors and log files are not purging. Due to this we are facing disk space issue and database dismounts. I have checked the DR log drive and found many ignored logs with M0o,2lw,ivf...extensions. As per my understanding if log files are not successfully replayed in the DR site backup will not purge it. From exchange server we are able to find the error event Event ID 459 Description: MSExchangeIS (2508) MB: The file C:\Logs\SG12\E2D000131B4.log is missing and could not be backed-up. Can you tell me whether i have to diagnose with the SCR log shipping or do i need to check with any other configurations. Please provide your suggestions.

You're going to have to bring this up with HP, I'm sorry to have to advise you.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Not sure why that log file is missing, however a full backup should work. If you've tried a full backup and it still fails, try the native WSB and test, if it works, then your issue is most likely related to DPM.Sukh

If the log file is missing, it's missing. What difference does it make what software you use? If you must (assuming only one database per storage group), dismount the database and verify that it's in a clean state. Then remove all the *.log files and *.chk files associated with that database/storage group. Remount the database to start a new log file generation. Then make a full/normal backup immediately -- don't wait, do it now . . . yes, RIGHT NOW! --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

In terms of the software, well, the logs aren't purging, so to simply rule out backups software, using the WSB is worth while doing. I've seen cases where WSB will truncate logs and not 3rd party product due to software updates needed, this may not be the case here as there isn't much detail but is a possibility.Sukh

How is the issue now?Xiu Zhang TechNet Community Support
