Welcome to a new article related to SQL Server. This article was created in the Coronavirus era. I really hope you are all fine. As always, we will try to help in your life with some tips about MS SQL.
In this new article, we will show how to restore a SQL Database using the move sentence.
Likewise, there is also the other side of this management software. These databases can also crash and lost all the million dollars data. But there is always a backup of every database. And to restore that database there is a lot of methods. One of the famous methods we will use to restore our SQL database. This method is known as a restore with move. We will explain to you how this method works and we will show you how to use it.
There are many causes that make the MS SQL databases fail:
- Power out that damage the hard disk.
- Hardware failures (because of the usage, virus problems).
- Corruption of Software.
- Natural disasters.
- Human errors.
- Hacker attack.
We need to use the backup when these problems occur in our database.

The SQL Server backup and restore part provides an important disaster strategy used for safeguarding crucial knowledge that is stored in your SQL Server databases. To reduce the danger to lose your data. You would like to make a copy of your knowledgebase to preserve modifications to your data on a daily basis. A well-planned backup and restore strategy helps shield the knowledgebase against data loss caused by a range of failures. Take a look at your strategy by restoring a group of backups so convalescent your info to arrange you to retort effectively to a disaster.
Let’s clear some myths about database restoration:
- You cannot restore a backup from a later version of SQL Server to an academic degree earlier version. as an associate example, an upgraded version of SQL backup won’t restore on to an older version of SQL instance!
- You cannot reinstate only single objects from a native SQL Server backup.
Now move ahead:
Now, when we need to restore the backup, it’s possible that the directory and/or the file structure on the target is not the same used in the source. For example, maybe when we backed up the first instance of DB on Server_one, the database files were on D: \\SQLServer. But we’re reinstating to Server_two which doesn’t even have a D: drive. In fact, the data file(s) is supposed to go on M:\\SQLData, and the log should go on L:SQLLog.
Let’s achieve this reinstating in two stages:
- Note down the logical and physical file names that you will be reinstating. It is possible to check the source server (using the sp_helpdb stored procedore) or you can use the FILELISTONLY.
- Write your reinstate statement WITH MOVE.
Let’s discuss about FILELISTONLY and WITH MOVE.
FILELISTONLY is a reinstate option in which you see the file names (logical, physical) restrain in the backup. This is significant to know because you won’t always have access to the source server.
To use this simply run:
RESTORE FILELISTONLY FROM DISK = '\\location\folder\DB_BACKUP_NAME.bak";
This will return a bunch of information which includes (logical and physical file name and file type and much more).
Let’s say that our results are:
|Logical Name||Physical Name|
|Database_one _log||D:\SQLServer\Database_one _log.ldf|
With that information, it is possible to use the RESTORE WITH MOVE statement.
RESTORE WITH MOVE
Remember, we said we needed to restore DB1 so that the data file is in M:\SQLData\, and the log file is in L:\SQLLog\. Here is our restore statement:
RESTORE DATABASE [Database_used]
FROM DISK = 'drive: \\location\folder\DB_BACKUP_NAME.bak"
WITH MOVE 'Database_one' TO 'M:\SQLData\Database_one.mdf',
MOVE 'Database_one_Log' TO 'L:\SQLLog\Database_one_log.ldf';
Once you know about this, then this method (RESTORE WITH MOVE) will help you a lot.
What to do if the backup is corrupt?
If the database backup is corrupt, is it possible to repair using the Stellar Toolkit for MS SQL. This software can repair the corrupt databases, restore the database from corrupt BAK files, and restores the SQL database admin and user passwords.
After this implementation, we can say that after the failure of the MS SQL database whatever the cause of failing (Human error, Disk Failure, natural disasters, etc.) we can restore our database using the move method which is the easiest way to restore MS SQL database I have ever seen. As we already discuss the age we are living in is full of revolutions and technologies. These types of restoring methods can help us a lot in daily life routines. I have tried my best to explain this method so that there are no pre-requirements to perform this operation for restoring the database. Each and every word can be understood by the layman. I hope you will find this article best ever in the list of Restoration of MS SQL Database.
