Database Recovery Considerations
Consider the following information before you perform specific recovery
procedures in the Exchange 2007 organization:
·
Determine the time that is required to
restore and play transaction log files. Performance in your environment may
vary significantly from the average, and you should consider log replay in
addition to restore time. If you perform weekly
·
To minimize the time that it takes to
recover an individual database, configure storage limits for the mailbox and
public folder stores to constrain databases to a maximum size limit.
·
To back up Exchange data using the ESE
streaming backup APIs or a VSS-based solution, the database must be online.
You can still back up an offline database manually. However, in that event,
manual checksum verification is required. In addition, performing an offline
backup of Exchange involves an interruption of service to clients.
·
You can back up and restore databases in
a storage group individually or simultaneously. As long as you do not exceed
the data bandwidth capacity of your hard drives, controllers, and backup
hardware, you can save time by simultaneously running multiple instances of
Backup to back up or restore databases.
