Exchange Server 2003 Database Level Restore Options

• Automatically dismount database before restore--To prepare your Exchange server before you restore, you must dismount the database stores within all storage groups that you want to restore. To do this automatically, enable this option. For information on how to dismount databases manually, see Database Level Restore Prerequisites.
• Allow database to be overwritten by restore--Before you restore, to prepare your Exchange server, you must allow each database store in the Storage Groups you want to restore to be overwritten. To do this automatically, enable this option. For information on how to do this manually, see Database Level Restore Prerequisites.
• Restore to Recovery Storage Group--Select this option when you want to restore data to a Recovery Storage Group. (Applies to Exchange Server 2003 only)

  Be aware of the following behavior:

  • This option does not appear on the Backup Agent Restore Options dialog when you protect with versions of the Arcserve Backup Agent for Microsoft Exchange Server older than r12.

  Be aware of the following limitations:

  • If you are restoring Exchange Server 2003 database level sessions that were backed using a previous version of the agent, you cannot explicitly restore data to a recovery storage group using the Backup Agent Restore Options dialog. For more information, see Prerequisite Tasks for Restoring Recovery Storage Groups on Exchange Server 2003 Systems.
  • If you performed a database level backup of an Exchange Server 2003 database using a previous version of the agent (for example, BrightStor ARCserve Backup r11.1 or BrightStor ARCserve Backup r11.5), and then upgraded the agent to Arcserve Backup version below r16, you can specify the Restore old sessions to Recovery storage group option on the Exchange Agent Configuration dialog. This option lets the agent restore the data to the recovery storage group. For more information, see Configure the Agent for Database Level Backup and Restore.
  • You can restore one storage group to a Recovery Storage Group, per job.
  • You cannot restore public folders to a Recovery Storage Group.
• Commit after restore--Commits the database after the restore is completed. If you are restoring a set, use this option only when you are restoring the last backup in the set. If this option is not selected, the database is left in an intermediate state and is not yet usable but is ready for subsequent differential or incremental restores.
  • Apply existing logs--If you enable this, both the existing logs and any new logs that will be restored are applied together in sequential order when the database is committed. If you do not select this, only the new logs will be applied (existing logs are not applied).

    Important! Do not use this option if the Exchange server that you are restoring data to is not the Exchange server you backed up from, the existing database is corrupt, or the new logs that will be restored are out of sequence with the existing logs. If you enable this option and the agent detects that logs are out of sequence, the agent automatically disables the option to prevent the job from failing.

  • Mount database after restore--Instructs Exchange Server to mount the database after the restore is completed. If you would rather manually mount your database, disable this option.

    Note: If Exchange Server fails to mount the database, check the event log for details. If you think Exchange Server failed to mount because of existing logs on the server, repackage and run the restore without the Apply existing logs option enabled.

  • Wait for the database to commit--If you enable this, the agent waits for Exchange Server to return the commit result before finishing the restore. This may take a long time depending on the number of logs Exchange Server is attempting to commit.
• Temporary location for log and patch files--Sets a temporary location on the Exchange Server machine to restore logs and patch files during the restore process. The temporary location you select must be empty before you restore and must have enough space for all the log files being restored. After the database commits the logs and patch files, they are deleted.

  Note: If you are restoring a series of full backups, incremental backups, or differential backups, you must use the same temporary location for all restore jobs.
