How to Recover a SQL Database and Allow Additional Log Backups
適用於: System Center Data Protection Manager 2010
The DPM recovery process uses SQL Server functionality to recover a database such that all uncommitted transactions are rolled back. The recovery process opens the transaction log to identify uncommitted transactions. Uncommitted transactions are undone by being rolled back, unless they hold locks that prevent other transactions from viewing transactionally inconsistent data. This step is called the undo, or roll back, phase.
In some circumstances, the SQL Server administrator might require the database to be restored in a mode that allows log backups to be selectively played back. Using DPM, you can recover a database and leave it in a restoring state in which additional log backups can be applied to the database.
To recover a database without transaction roll back
In DPM Administrator Console, click Recovery on the navigation bar.
Using the browse functionality, select the database to recover.
On the calendar, click any date in bold to obtain the recovery points available for that date. The Recovery time menu lists the time for each available recovery point.
On the Recovery time menu, select the recovery point you want to use. You can select any recovery point except Latest.
In the Actions pane, click Recover.
The Recovery Wizard starts.
On the Review recovery selection page, click Next.
Select Recover to original SQL Server location or Recover to any SQL instance, and then click Next.
If you select Recover to any SQL instance, on the Specify recovery destination page, specify the instance of SQL Server to which the database should be recovered.
On the Specify Database State page, select Leave database non-operational but able to restore additional transaction logs.
Select Copy SQL transaction logs between the selected recovery point and latest available recovery point, specify a copy destination for the transaction logs, and then click Next.
DPM must have Write permission for the copy destination for the transaction logs.
Specify recovery options for network bandwidth usage throttling, SAN-based recovery, and e-mail notifications, and then click Next.
On the Summary page, review the recovery settings, and then click Recover.
Use the Restore Transact-SQL command with the HeaderOnly argument to retrieve the header information for the transaction logs. The header contains information that allows the log backup sequences to be correctly ordered.
Use the Restore command with the Log argument to apply the desired logs to the database in the right order.
For more information on the Restore command, see RESTORE Arguments (Transact-SQL) (https://go.microsoft.com/fwlink/?LinkId=104665).
