Review the following information before you perform restores of Exchange Server:
Restore all databases in a storage group at the same time and before the transaction logs are committed and the databases are mounted.
When an administrator restores individual databases or transaction logs, the administrator should have a thorough working knowledge of Exchange Server databases, transaction logs, and utilities. If the correct files are not restored, the database(s) may fail to mount.
Do not restore Microsoft Exchange Mailboxes:\ or Microsoft Exchange Public Folders:\ objects and Microsoft Information Store:\ objects at the same time. Do not restore mailbox or public folder items from a GRT-enabled backup and a streaming backup at the same time. You must dismount databases before you restore them. But because they are dismounted, the attempt to restore mailbox objects fails. Or the restore of the Exchange mailbox items can finish before the restore of the Exchange databases starts. In this case the restore of the Exchange databases overwrites the restored mailbox objects.
To restore full and incremental backups, you can restore all the backups in a single operation. Or you can restore the full backups and incremental backups individually. If you restore all the backups in a single operation, NetBackup performs a commit after the last incremental is restored. If you restore the backups individually, select the following options when you restore the last incremental backup set: and .
(Exchange 2007 and earlier streaming restores) Make sure the temporary location for log files is empty before you start a restore job. If a restore job fails, check the temporary location (including subdirectories) to make sure log files from a previous restore job are deleted.
NetBackup copies logs to the Exchange working directory. It creates a subdirectory for each storage group being restored. After the database is restored, Exchange applies the log files from the temporary location to the database, and then it applies the current log files. After the recovery is complete, Exchange deletes the log files from the temporary location (including any subdirectories).
A restore of Exchange Server files always
overwrites existing files. (For example, if Pub.edb
already exists on the target machine, it
is replaced with the copy from the backup.)
