Performing Database Level Backups and Restores › Database Level Data Restore › Exchange Server 2007 Database Level Restore Options

Exchange Server 2007 Database Level Restore Options

The Backup Agent Restore Options dialog displays the default options for a full backup session.

Note: For full backup sessions, the option, Automatically restore necessary previous sessions for incremental and differential restore, is disabled by default. For incremental and differential backup sessions, the option is selected and enabled by default.

Automatically dismount databases of destination Storage Group 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 databases of destination Storage Group to be overwritten--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.

• Automatically restore necessary previous sessions for incremental and differential restore--This option applies to incremental and differential sessions only.
  • When you enable this option for incremental session restores, the last full backup session and necessary incremental backup sessions will be restored in sequence.
  • When you enable this option for differential session restores, the last full backup session will be restored before restoring the selected session.
• Restore to Recovery Storage Group--This option lets you restore the databases to the Recovery Storage Group (RSG). When you select this option you can specify a path to the RSG using the Backup Agent Admin utility. Through the Backup Agent Admin, the agent creates a subdirectory to the path specified for the RSG labeled as follows:

  \RSG_<Original SG Name> 
  

  The variable <Original SG Name> represents the name of the source storage group.

  Notes:

  • For more information about using the Backup Agent Admin to specify the path for the RSG, see Post-installation Tasks on Exchange Server 2007 Systems.
  • If the RSG already exists in a different path, or the existing RSG represents a different storage group, the agent removes the existing RSG and recreates it for the destination storage group.
  • The contents of the subdirectory “\RSG_<Original SG Name>” will be emptied before the agent creates the Recovery Storage Group.

Last Backup Set Options

• Run recovery after restore--Enable this option when you want to run recovery 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 a subsequent differential or incremental restore.
  • If you are restoring data to its original location, all of the existing logs will be played back into the database during the recovery process. This process ensures that the databases will be restored to the current point in time. However, if the existing logs are corrupt or not in sequence, the recovery will fail.

  Note: If you want to restore the storage group to the point of the last backup, you can use the Restore files to their original location restore method and do the following:

  1. Dismount all of the databases in the storage group.
  2. Delete or move the existing log files and the .chk file for the storage group to a different location.
  3. Restore the storage group using the Run recovery after restore option.
  4. Perform a full backup of the storage group.

     Note: To ensure that subsequent differential and incremental backups are properly sequenced with the last full backup, you must perform a full backup of the storage group at this time. If you do not perform a full backup at this time, your attempts to restore the subsequent differential and incremental backups will fail.

• 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.
• Restore selected mailboxes to live database from Recovery Storage Group--You can enable this option only if the Restore to Recovery Storage Group option is selected. This option lets you browse the restore source down to the mailbox level and select individual mailboxes as the restore source. When you restore data with this option enabled, the agent restores the entire database to the recovery storage group (RSG), and then restores the selected mailboxes to their original mailbox location from the RSG. The original mailbox is the mailbox that contains the same GUID as the source mailbox.

  You can also use this option with respect to Dial Tone restore strategies for disaster recovery on Exchange systems. Dial Tone restore is a process that lets you restore email service to users quickly and then restore the users' previous data. For more information about Dial Tone restore strategies, see the Microsoft TechNet web site.

  For more information, see How to Select Restore Source Objects.

• Advanced Options--When you click this button, the Restore Mailbox Options dialog opens.

  Important! The Advanced Options button is available only if the Restore selected mailboxes to live database from Recovery Storage Group is selected.

Advanced Options

The Restore Mailbox Options dialog contains three properties sheets that let you configure advanced options that apply to how Arcserve Backup restores mailboxes. From the Restore Mailbox Options dialog, you can perform the following tasks:

• Configure Restore Options
• Configure Folder Filters
• Configure Message Filters

Restore Options

The Restore Options properties sheet contains the following fields:

• Global Catalog Server Name--The name of the global catalog server to use for searching for the target mailbox.

  Note: If you leave this field blank, the default global catalog server will be used.

• Maximum number of bad items--Specifies the number of corrupted items in a mailbox to skip before the exporting mailbox operation fails. The default value is 0.
• Maximum number of threads--Specifies the maximum number of threads to use for the restore. The default value is 4.
• Target Folder--Identifies the mailbox folder to which all data will be restored.

  Notes:

  • If you specify a target folder, all other folders will remain unchanged.
  • If you do not specify a target folder, all data is restored to its original location.
  • If you are restoring messages to their original folder, Arcserve Backup will not restore messages that exist in their original folder.

Folder Filters

The Folder Filters properties sheet contains the following fields and buttons:

• Choose Filter Type--Specifies whether you want the specified folders to be excluded or included during mailbox export.
• Full path of folder for filtering--Specifies the list of folders to include or exclude during the mailbox export.
• Specify a path--Specifies the path of the folder filter.

  Note: All folder paths must be preceded by the backslash "\" character.

• Add a path--Click Add to add the specified folder to the folder list.

  Note: To remove a folder from the folder list, select the folder from the list and then click Remove.

Message Filters

The Message Filters properties sheet contains the following fields and buttons:

Keywords

You can filter messages using a keyword contained in the subject, content, and the attachment file name. Click Add to add the keyword to the keyword list. To remove a keyword, select the keyword and then click Remove.

• Subject filters--Specifies the keyword filters for subjects of items in the source mailbox. This filter will find the search string even if it is part of a word.

  Note: This filter is not a whole-word search.

• Content filters--Specifies the keyword filters for the message bodies of items in the source mailbox. This filter will find the search string if it is part of a word.

  Note: This filter is not a whole-word search.

• Attachment filters--Specifies the keyword filters for attachment file names of messages in the source mailbox. If an Attachment filter string matches a word or part of a word in one of the message attachment file names, the message will be restored.

Note: Keyword filters for messages can be classified as include filters. Filters of this type let you restore only the messages that satisfy the filter search criteria. Therefore, if the filter search criterions for subject, content, and attachment filters are all satisfied, the message will be restored.

Start Time and End Time

Specifies the start date (and time) and end date (and time) of messages that you want to filter and export from the source mailbox. Only messages in the mailbox with received dates that are after the start date and before the end date will be exported. The start date must precede the end date.

Locale

Use the Locale filters to specify source message locale. Only messages with the specified locale are restored.
