- Page 18 Optimize Mailbox Layout: It is best to limit the no. of critical mail stores/mailboxes per server. Encourage separation of mail stores on separate servers. Separate Logs and mail stores on different volumes. Here are some of the database volume characteristics with I/O patterns: Jet database (.edb): This is used to hold all data submitted by MAPI clients.

Page 19: Backup Strategy
Backup strategy This solution used RAID 5 for the backup-to-disk LUNs in order to maximize space and provide single disk failure protection. In today‟s information-centric world, any loss of data could incur heavy financial penalties leave alone other inconveniences caused. Regularly saving and protecting data has become mandatory and is no longer a luxury. - Page 20 These snapshots also allow regular scheduled backups to tapes for archival purposes. With the enhancements in Exchange 2003 and the wealth of recovery features provided in iTX, recovery of mail store has become very easy. The main benefit here is that there is no need for a spare disaster recovery server in its own Active Directory forest to recover a single mailbox or single mailbox store, as was required in Exchange 2000.
