Restore Deleted Data SQL Server Using Manual Method

If you guys want to go for a manual solution, then having a complete backup of the database is very crucial. This way, users can save time and effort. They can also minimize the chances of errors. However, as it is a manual solution, there is still some scope for errors left here.

As per recent surveys, users who maintain frequent & up-to-date backups of their SQL server database, suffer less damage during any accidental or intentional deletion of data.

As we know that a differential backup does not work properly in every scenario, we need to be careful of it. There are plenty of prerequisites present if users want to execute the operation using this way.

Follow the steps mentioned below to recover deleted SQL records if you have a full backup already:

  1. The very first task here is to simply restore the backup of your SQL database.
  2. Now users need to keep both of their databases individually or separated.
  3. Here, the objective is to find out the data not present in the live database.
  4. Finally, users have to perform the UPDATE operation on altered records.

LSN Method to Recover Deleted SQL Records Safely

LSN means a Log Sequence Number. Each record in any SQL server table has its own LSN in a unique log file. This way, users can recover the deleted data if they know the exact time of deletion. Users must have the full recovery model or the logged recovery model if they need to execute the recovery. This is the prerequisite of this method.

1st-Step. Check existing rows number in the table from which the data is deleted. Use the below command for that:

SELECT * FROM Table_name=

2nd-Step. Here, users need to take a log backup to proceed further.

USE DatabaseName
GO
BACKUP LOG [DatabaseName]
TO DISK = N’D:\DatabaseName\RDDTrLog.trn’
WITH NOFORMAT, NOINIT,
NAME = N’DatabaseName-Transaction Log Backup’,
SKIP, NOREWIND, NOUNLOAD, STATS = 10
GO

3rd-Step. Try to get the transaction ID of the records you accidentally deleted. This way, you can get the information of rows deleted.

USE DatabaseName
GO
Select [Current LSN] LSN], [Transaction ID], Operation, Context, AllocUnitName
FROM
fn_dblog(NULL, NULL)
WHERE Operation = ‘LOP_DELETE_ROWS’

4th-Step. To restore deleted SQL records, try to find the specific time of data deletion. Transaction ID helps in getting this information. Therefore, you can get the LSN.

USE DatabaseName
GO
SELECT
[Current LSN], Operation, [Transaction_ID], [Begin Time], [Transaction_Name], [Transaction SID]
FROM
fn_dblog(NULL, NULL)
WHERE
[Transaction ID] = ‘000:000001f3′
AND
[Operation] = ‘LOP_BEGIN_XACT’

5th-Step. Start recovering the data deleted accidentally using the below command.

Recover Deleted D USE DatabaseName
GO
RESTORE DATABASE DatabaseName_COPY FROM
DISK = ‘D:\DatabaseName\RDDFull.bak’
WITHMOVE ‘DatabaseName’ TO ‘D:\RecoverDB\DatabaseName.mdf’,
MOVE ‘DatabaseName_log’ TO ‘D:\RecoverDB\DatabaseName_log.ldf’,
REPLACE, NORECOVERY;
GO

6th-Step. At last, check if you’re database objects are back or not.

USE DatabaseName_Copy GO Select * from Table_name
