Exchange 5.5 SP4. I need to restore my Directory Database from 3 months ago. I am wondering if it will backfill itself from the other servers in the site? The Disaster Recovery white papers seem to suggest that it will. I would also like to know if there are any 'gotchyas' I should look out for?
Here is my specific problem. Everytime Online IS Maintenance runs the dsamain process maxes out the CPU to 100%. A Reboot fixes the problem until IS Maintenance is run again. I ran eseutil integrity check on it and it reported bad pages. So I am assuming this is my problem. Unfortunately it is not effecting client performance so it has gone unnoticed for 3 months. The only thing that alluded us to the problem was the backups started running into the day? The Exchange Backups are working, but backing up this corrupt directory. I would prefer to use another server and move all mailboxes onto it. But this would be expensive as the server is is a very remote location.
So... Can I restore a 3 month old directory database without any issues - Apart from the time it takes to replicate/backfill from the other servers?
