SQL Server database is the foremost choice of a large number of small and big-sized companies. These include world-famous organizations like Oracle, Netflix, IBM, Amazon, LinkedIn, Uber, Instagram, and many more. These organizations trust SQL Servers for data storage, extraction, modification, and management. 

Nevertheless, with a voluminous amount of stored data comes a heavy responsibility of protecting it from unwanted instances like data theft, data loss, or data destruction. This necessitates the need for admins to backup the SQL Server database

This will allow them to quickly recover data in the event of a corrupted or damaged database. Admins may use manual methods or a third-party SQL recovery tool such as Stellar Repair for MS SQL to repair the database successfully from the backup file.

But why do the databases become corrupt? Let’s try to find the reasons right here followed by the ways to repair corrupt backup.

Reasons for a corrupt database

The corruption of an SQL database may result due to media failure, hardware failure, or a natural disaster.

Failure of hard drive

Hard drive failure is one of the prominent reasons behind a corrupted database, which can happen due to physical damage, controller issues, or manufacturing defects with the storage device. In any case, the failure may lead to severe data loss or inconsistencies.

Power cutoff

In the absence of an uninterrupted power supply (UPS) system, unexpected power outages can have an adverse impact on database operations. The need is hence to connect your PC to a UPS system and make proper shutdown a habit. This will protect your data despite power outages.

Software glitches

Bugs or glitches in the DMBS software or application code can result in data consistencies and even database corruption.

Hasty actions

Any type of work done in haste and hassle can lead to inconsistencies and permanent data loss in the database. This may include actions like making incorrect input, deleting sensitive data accidentally, improper database operations, and so on.

Malware attacks

The continuously rising incidents of cyber attacks pose a major threat to the safety and security of databases. Failing to stop intrusion can lead to database infiltration and then corruption. At the worst, you will lose all the data. Regular data scanning and software updates could save the database from such breaches.

Software incompatibility

At times, using obsolete or incompatible software can cause database corruption. Integrating the software with a third-party application can make your database unstable. Regular software updates will reduce the risks arising due to incompatibility issues of the software.

To make your database work again, creating a recent backup would be a feasible solution.

Why is database backup important?

Creating a database backup is the foremost way to protect your data from damage in case the database becomes corrupted. You can restore your data from the previous backup. Other backup related processes to follow may include:

  • Running test procedures for backup restoration 
  • Storing backup copies in an off site and safe location

 Backups also hold high importance to carry out routine administrative purposes. For examples:

  • Copying database across servers
  • Database mirroring and archiving
  • Enabling Always On availability groups setting

Concisely, backup is the sole method to safeguard your data through manual ways. This necessitates the need for creating regular backups. Let’s learn more about it.

Creating Backup of SQL Server Databases

You can try multiple methods to create backups of your SQL Server databases. Let’s learn about them one after another.

Creating a Full Backup Using SSMS

You can use SQL Server Management Studio to create a full backup of your database and restore it later if required. Here are the easy steps:

  1. In the object explorer, click Databases
  2. Right-click the database for which you want to create a backup
  3. Click Tasks 🡪 Backup
  1. In the Back Up Database Window, Choose Full as Backup type under Source.
  2. Under Destination, choose Back up to: Disk
  3. This will save the back up to a default location on your computer. Click OK.
  4. If you want to save the backup to a different location, click Remove and then click Add to choose the name and destination of the database backup file.
  5. Save the file with .bak extension in the selected folder
  6. Click OK to end the backup process.

Schedule an Automatic Backup of SQL Server database

If you are not getting time to create backup, you can schedule the process at a certain time. Here are easy steps to do so:

  • Open SQL Server Management Studio (SSMS)
  • Create a full backup as shown earlier.
  • At the top of the Backup Database window in the right pane, click the small triangle pointing downward next to Script.
  • Click Script Action to Job
  • Visit the Schedule page 🡪 Click New button to create a fresh backup schedule.
  • You can schedule an hourly, daily, weekly, or any other job according to your comfort.

Create Full Database Backup using Transact-SQL

  1. In the Backup Database window, click Script 🡪 Script Action to New Query Window, or simply click Script.
  1. It will open a new query window with the below T-SQL command pre-written as shown below. 

BACKUP DATABASE [SQL_TEST_DB] TO  DISK = N’C:\Program Files\Microsoft SQL Server\MSSQL16.SQLEXPRESS\MSSQL\Backup\SQL_TEST_DB.bak’ WITH NOFORMAT, NOINIT,  NAME = N’SQL_TEST_DB-Full Database Backup’, SKIP, NOREWIND, NOUNLOAD,  STATS = 10

GO

  1. You simply need to execute this query to create backup through the SQL query.  


Create a Differential Backup 

The method to create a differential backup is the same as in the case of full database backup. 

Just make sure to select Differential in Backup Type. Other steps are the same as earlier. 

Create Differential backup using Transact-SQL

  1. The method is the same as in the case of Full backup. Just make sure to select Differential in Backup Type in the Back Up Database window.
  2. Click Script 🡪 Script Action to New Query Window, or just click Script.
  3. It will open a new query window with the below T-SQL command pre-written as shown below. 

BACKUP DATABASE [SQL_TEST_DB] TO  DISK = N’C:\Program Files\Microsoft SQL Server\MSSQL16.SQLEXPRESS\MSSQL\Backup\SQL_TEST_DB.bak’ WITH  DIFFERENTIAL , NOFORMAT, NOINIT,  NAME = N’SQL_TEST_DB-Full Database Backup’, SKIP, NOREWIND, NOUNLOAD,  STATS = 10

GO

  1. Execute the query to create the differential backup.

Restore SQL Database Server

Just like multiple methods to create backup of your SQL Server Database, you can try many ways to recover or restore the data in the SQL Database. While admins prefer manual methods, using a third party software such as Stellar Repair for MS SQL is even better option to recover a corrupt .BAK file. It will make extracting database out it much easier. We will discuss all those methods right here.  


Database Restore using SSMS (from Full and Differential Backup)

The steps to restore the database from a recent backup and recover its contents are as follows.

  1. Object Explorer 🡪Right-click Databases 🡪 Restore Database
  1. Select the database that you want to restore as shown above.
  1. Choose the Backup Type, whether Full or Differential from which you want to restore the database.
  1. Click OK.

Database Restore using Transact-SQL

  1. Click Object Explorer 🡪 Databases 🡪Restore Database
  2. In the Restore Database window, select the Database that you want to restore.
  3. Select the Backup Type from Full and Differential 
  4. Click Script on the top of the Restore Database Window in the right pane.
  5. A New Query window will pop up which will contain the following T-SQL query pre-written.

USE [master]

RESTORE DATABASE [SQL_TEST_DB] FROM  DISK = N’C:\Program Files\Microsoft SQL Server\MSSQL16.SQLEXPRESS\MSSQL\Backup\SQL_TEST_DB.bak’ WITH  FILE = 1,  NOUNLOAD,  STATS = 5

GO

  1. Execute the query to restore the database.

Whether you use SSMS or a T-SQL query, you can perform backup and restore of your database through any of these methods. However, you may face problems while performing these processes due to corrupted data, large size of the database, or any other reason. Using Stellar Repair for MS SQL would be a better option to recover and repair SQL database server to avoid such circumstances.
