Let us see the step by step approach to backup SQL Database using the SQL Server Management Studio and SQL Query. For this Backup SQL Database demonstration, we are going to use the Adventure Works 2014 database in our SQL Server.
Before we start performing the SQL Server backup, let me show you the actual size of a database. For this, right-click on the SQL Server Adventure Works Database, and select the properties from the context menu.
As you see, it is 207.25 MB. Remember, you can use this properties window to check the Permissions as well.
Or you can use the following Stored Procedure to check the database size.
-- Backup SQL Server Database Example USE [AdventureWorks2014] GO EXEC sp_spaceused;
Backup SQL Database Example
To backup the SQL database, right-click on the Adventure Works will open the context menu. Please select the Tasks option, and then select the Back Up.. option.
Once you select the Back Up.. option, a new window called Back Up database will open.
Database: You can use the drop-down list to change the Database that you want to backup at any point in time.
Backup Type: There are two types of SQL Database Backups, and they are Full and Differential. For now, we are selecting the Full.
Back up to: This property has two options: Disk and URL. It means you can save the Backup file in either URL (Company Websites), or DISK. For now, we are leaving the default Disk.
If you observe the below screenshot, SSMS automatically provided the default path as the location to save the backup file. You can use Add, Remove buttons to add a new path and remove the existing path. First, let me remove the default path by selecting the path and clicking the Remove button.
To add a new path, please click on the Add button. By clicking that button, a new window called Select Backup Destination will open. By default, it is pointing to the default Backup path. Click on the … button to change the destination location
From the below screenshot you can see, we are selecting the D drive -> 1 BACKUPS Folder -> AdventureWorks2014Dup as the file name
Please cross-check all the fields before we proceed to the next tab.
Under the Overwrite media section, please change the back up to the existing media set option from Append to the existing backup set to overwrite all existing backups.
Use this tab, to set the expiry date and time, or to encrypt the backup with custom certificates.
If your database size is huge, please select the Compress backup option.
Once you complete configuring all the required settings, please click OK to create a Database backup in SQL Server.
Let me open the folder. From the below screenshot, you can the backup file.
Create an Encrypt Backup of SQL Database
First, let me change the Destination folder, and file name to AdventureWorks2014Dup2
To create an encrypted Database backup in SQL Server, you have to select the Back up to a new media set and erase all existing backup sets option.
- New Media set name: Please provide the name of the backup file.
- New media set description: provide a valid description, which is optional.
Under the Algorithm property, you can select the Algorithm as per your requirements. For now, we are choosing the AES 256 algorithm
Currently, we don’t have certificates; that’s why it is showing empty. But in real-time you might have few certificates to select.
Click OK to close the window.
Backup SQL Database using T-SQL Query
The following SQL examples will help you understand the steps involved in creating database backup files to file system using the transact SQL queries.
Backup SQL Database to Default Location
This example will create a backup file to the file system at the default location. And the location is C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup. Here, the path may be different for you. It all depends upon the SQL Version and installed location
-- Backup SQL Server Database Example BACKUP DATABASE AdventureWorks2014 TO DISK = 'AdventureWorks2014Dup3.bak' GO
From the below screenshot, you can see the backup file
Backup SQL Database to Custom Location
This example will create a backup file to the file system. Here we are going to use the custom location. Please change the location as per your requirements.
-- Backup SQL Server Database Example BACKUP DATABASE AdventureWorks2014 TO DISK = 'D:\1 BACKUPS\AdventureWorks2014Dup4.bak' GO
From the below screenshot, you can see the Database backup file in the D folder.
Differential Backup SQL Database to Custom Location
This example will create a differential backup, and save that backup file to the file system.
-- Backup SQL Server Database Example BACKUP DATABASE AdventureWorks2014 TO DISK = 'D:\1 BACKUPS\AdventureWorks2014_Differential.bak' GO
From the below screenshot, you can see the SQL differential backup database file in the D folder.
