I dismounted the database, moved the log files to a different location and remounted the database. &nbsp;Upon startup, new log and checkpoint files were created and a backup ran cleanly. &nbsp;Thanks for the advice!!

We’re running Exchange 2010 SP1 (no roll-ups installed) under Windows Server 2008 R2 and trying to backup the Exchange volume using Windows Backup utility. &nbsp;It was running fine for over a month and then I noticed event ID 565 (consistency check failed) and event ID 518 (pointing to missing log files). &nbsp; The backup completes but gives a warning “The application will not be available for recovery from this backup. &nbsp;The consistency check failed for the component …”. <br />
<br />
Looking further at the information contained in event ID 518, indeed there are 2 log files missing. &nbsp;How they went missing is anyone’s guess but the question is, how do I get a good backup so that my accumulating log files can be eliminated? &nbsp;<br />
