Procedure of taking backup of MS SQL Database

In this blog, I have discussed the process of taking backup of MS SQL Database, the types of backups, and steps to take up the backup.


MSSQL is a relational database management system (RDBMS) built for the basic function of storing retrieving data as required by other applications. It can be run either on the same computer or on another across a network. It is a highly scalable product that can be run on anything from a single laptop to a network of high-powered cloud servers, and anything in between.

Backup Process Basics

SQL Server allows three basic types of Microsoft SQL Server backup:

  1. Full backup
  2. Differential backup
  3. Transaction log backup Now let’s look at different types of backups type.

1.Full Backup

A backup containing all the data from the database in question is known as full backup. Such as file sets and file groups, as well as logs to ensure data recovery. These backups create a complete backup of your database as well as part of the transaction log, so the database can be recovered.

2.Differential Backup

A differential database backup is based on the most recent, previous full backup. A differential database backup only captures the data that has changed since the last full backup. A previous full backup is needed if you want to restore a differential backup.

3. Transaction log backup.

Backup taken of transaction logs is known as transaction log backup. It includes all log entries that were absent in the previous transaction log backup (available in the full restore model only).

Here we will see the steps of taking Full Backup of MS SQL.

DB Backup Process: -

Step 1: Select database which you want to take the backup of and click on the right, you will see a screen pop as shown in the following snapshot. Then Go to the task and select ‘backup.’

Step 2. Select backup type (Full\diff\log) and make sure to check destination path which is where the backup file will be created.

Step 3. Go to Backup option & and select the compress backup if required.

Step 4. Go to add button and select the path where you want to keep the backup file. Make sure the backup location is accessible.

Step 5. Select the path and type of the backup file name with .BAK and click ok.

Extension of Backup:

  1. For Full backup (.BAK)
  2. For Transaction Log (.trn)
  3. For Differential (.dif)
  4. For File & File group (.fil)

Step 6. Go to Ok button.

Step 7. Go to OK button then again OK

Step 8. Backup has been completed and click ok again.

Step 9. Check the Backup file where you keep the backup.

If your database size is big, you will need to combine full, differential and transaction log backups. If your database is big and it does not change too much, a differential backup will take less space than a full backup and you will save a lot of space. Do not store your backup on the same drive than the database. If possible, try to store your backup on another server or even better on another physical place.


Database backups are vital for recovery in any disaster scenario. You should plan proper backup policy, validate the restoration plan as per the criticality.
