Restore Databases

The Restore wizard guides you through the process of restoring a database (full or differential), transaction log, files, or filegroups.

Tip: Database backups created with LiteSpeed Version 8.x cannot be restored using older versions of LiteSpeed.

NOTES:

Scenario

You need to restore a LiteSpeed disk backup to a new database on another SQL Server. Copy the backup files needed for restore to another server and run the Restore wizard. ClosedClick here to see additional information for this scenario.

To run the Restore wizard

  1. Select the Backup Manager pane (CTRL+1).
  2. In the Navigation pane, select a database to restore and click the Restore or Automated Restore button. Alternately you can right-click a database and select Restore or Automated Restore from the menu. If you clicked Restore, click one of the following. If you clicked Automated Restore, review the automated restore information below.

    • Database (full or differential)—Restore database only.
    • Files and Filegroups—Restore files and filegroups only.
    • Transaction Log—Restore transaction log only.

      Tip: The database (full or differential), files and filegroups, and transaction log restore types use the restore wizard pages listed in the steps below: restore destination, backup source, backup content, recovery options, data files, scheduled restore, execute script, and finish.

    • Attached Files—Restore attached files only.

      Tip: The attached files type uses the restore wizard pages listed in the steps below: restore destination, backup source, backup content, data files, attached files, scheduled restore, execute script, and finish.

    • Automated Restore—Restore the most recent full backup and optionally differential and transaction log backups. If you select this option, the Restore wizard creates an Automated Restore job. Backup files can be restored immediately or restored in the background.

      Tip: The automated restore type uses the restore wizard pages listed in the steps below: restore destination, backup source, backup files, restore options, database integrity, database files, scheduled restore, notification, execute script, and finish.

  1. Review information on the Restore Destination page. Select the Kill all current connections before restore checkbox to obtain exclusive access to the selected database. Additionally, you can select the View current activity link to view the database connection activity table. A database cannot be restored unless the restore process has exclusive access to the database. No user connections can exist when performing a database restore.

    Caution: Automated Restore for multiple databases - When running restores for multiple databases, we recommend that you use the %DATABASENAME% variable to automatically generate an original database name for database(s) going to be restored. When running restores from multiple servers, different databases with the same server name can be overwritten. To prevent this, the variable %SOURCESERVER% adds the source server name (server+instance) to the target database name when running multiple automated restores. For example: %SOURCESERVER%_%DATABASENAME%.

  2. On the Backup Source page, select Database to restore from a specific database's backup history, or select Device to manually select files to restore.

    Database

    If you select Database, the database you are restoring is displayed. You can select another database using the Database drop down selector. Use the SQL Server drop down selector if the database is on a different SQL Server instance.

    TIP:You can do point in time restores, restoring from a specific date and time or a time period (for example four hours prior to recovery).

    TIP: The restore type option Restore Verify Only in combination with the backup type Verify the latest full or differential backup is less time consuming for full and differential backups or fast compression backups where you only want to verify the latest backup, rather than the full and the latest differential. For backups that are run every day this will serve to verify all backups.

    If you selected Automated Restore, review the following for additional information.

    Restore from

    Select SQL Server and databases to specify the source from where to search the backups for automated restore.

    NOTE: The restore from parameters help LiteSpeed to narrow down its search for the required backup files in the source folders.

    Use the drop-down treeview to add multiple sources from the System and User parent nodes. Select User databases and all subordinate user databases are automatically selected. Individually select and deselect databases using the checkbox next to it.

    For AlwaysOn availability groups, you may need to specify both SQL Server (primary and secondary) to allow LiteSpeed to search backups among all replicas. To specify a secondary SQL Server, set "Automatically add all the Availability Group replicas to the search list" option.

    Latest backup search method

    Select one of the following options:

    • Folder scan—LiteSpeed will search the specified folder for the most recent database backups. You can configure LiteSpeed to search subfolders and filter backups using the specified file extensions.

    • Specific backup file name—You can use this option to automate restore operations if the same file gets overwritten during the backup or if new backups are always appended to the same file.

    NOTES:

    • If restoring a striped backup, you can specify multiple locations/filenames.
    • You can enter several backup extensions per path. Separate them with commas or semicolons.
    Backup type

    Specify backup types to use for the restore. Select one of the following options:

    • Full—The most recent full database backup.

    • Folders for log files—To enter a new location for all LOG files. Click the ellipsis button to browse and select other folders for log files.

    If Automated Restore selected, the following options can be selected:

    • Use SQL Server instance default locations - default SQL Server values will be used for DATA and LOG files. Check the SQL Server options.
    • Restore to locations from backup set - Automated Restore will use locations from the backup set. The locations must be available at the selected destination SQL Server instance.
    • Custom locations for data and log files — allows to set default folders for DATA and LOG files and optionally set path to all or some DATA and LOG fils by its logical file names. The following fields have to be defined for every optional file path:
      • Logical Name - logical file name of the DATA or LOG file
      • Database - restoring database name
      • Restore As - full path to a new DATA or LOG file location

     

    Processor affinity

    Click to select which processors LiteSpeed can use. The default is 0, which allows LiteSpeed to use all available system processors.

    Logging level

    Select one of the following options:

    • None—LiteSpeed does not write a log file for the backup or restore operation.

    • Verbose—LiteSpeed writes a log file for the backup or restore operation.

    • Verbose. Log file is removed on success—LiteSpeed only saves log files if the backup or restore operation fails. If it succeeds, LiteSpeed does not save the log.

    Network resilience

    If LiteSpeed fails to write disk backups or reads from disk, it waits and retries the operation. You can enable and disable and control the number of times to retry and the amount of time to wait before retrying.

    • Number of times to retry any given read/write attempt—The default is 4 retries. The maximum allowed setting is 1000 retries.
    • Wait period before each retry attempt (in seconds)—The default period to wait before retry is 15 seconds The maximum allowed setting is 300 seconds.
