Exchange server disaster recovery - no information store!
We recently had a catastrophic hardware failure of an exchange server on a relatively small domain based network. Bascially we lost 3 scsi hard disks in quick succession meaning that a DR from backup was the only solution onto a spare server with identical hardware configuration.
Windows 2003 Server SP2
Microsoft Exchange server 2003 (latest sp)
Arcserve 12 sp2 Backup server
Managed to do the DR 'by the book'. And now have a restored server.
However, we have noticed the information store service is not starting, and a quick examination reveals that the .edb files are missing. We have also noticed that the .edb files are missing from the previous backups. We know why as the .edb was moved to a different volume, but the change not made in the backup to ensure the information store on the new volume was backed up too!
However, we DO have recent brick level backups of the individual users mailboxes. Obviously we cannot restore these, as there is no information store to restore to!
Any suggestions of how we move forward with this?
Just some ideas:
a) Create a brand new info store and restore the brick level back to these?
b) Restore a 6 month old version of the information store of which we should have on archived backup (before it was moved to another volume), and then restore users folders on an individual brick level basis of which would bring them up to date.
Thanks for any advice with this.
