Ms sql recovery from the transaction log
Restoring the MS SQL Server database from the transaction log may be necessary in the event of a database failure or damage. The transaction log contains information about all changes made to the database since the last backup.
To perform a restore operation from the transaction log, follow these steps:
1. Make sure you have a full backup of your database and all subsequent transaction log files (.trn).
2. Open Microsoft SQL Server Management Studio and connect to the server instance of the appropriate version.
3. In the "Object Browser" window, select the required database for which you need to perform a gradual/partial update operation to the current state based on log files
4. Click the right mouse button on the selected Database -> Tasks -> Restore-> Database...
5. On the "General" page, specify the name of the target database and the path for the saved application files (Data Files).
6. Switching between sections: Options, Transaction Log – specifies what action will be performed on the data.
7. On the "Options" page, select the "Leave the database non-operational, and do not roll back uncommitted transactions" option.
8. On the Transaction Log page, select the From file: checkbox, and then click the Add button to add transaction log files (.trn) in order.
9. After that, you can perform the Restore Database operation
10. Upon completion of the recovery process from the transaction log, your database will be updated to the latest state based on the information from the log files.
It is important to remember that successful recovery can only be achieved if all backup copies and transaction log files are preserved.
