Export SQL Server Database to BAK File

How to Export SQL Server Database to .bak File

Using SQL Server Management Studio (SSMS)

Open SQL Server Management Studio and navigate to the Object Explorer. Expand the server tree and then the Databases folder. Right-click on the database you wish to back up and hover over Tasks. Select Back Up... to open the Back Up Database dialog box. The database you selected will appear in the dropdown list. Confirm the backup type and destination. To change the location, use the Add button. Click OK to begin the backup process.

Using T-SQL BACKUP Command

For the T-SQL approach, use the BACKUP DATABASE command to create a .bak file for your database. Confirm the backup path and use the ellipses to navigate to a specific file if necessary. To restore a database from a .bak file, employ the RESTORE DATABASE command.

Using PowerShell

Ensure the SqlServer module is installed by running Get-Module -Name SqlServer. If not, install it with Install-Module -Name SqlServer. In PowerShell, omit credential details when running within SSMS. Use the Backup-SqlDatabase cmdlet and specify the -BackupAction parameter for a full backup, though it is optional. Set the location and backup file name with the BackupFile parameter. For secure backups, use a Shared Access Signature when specifying the SQL Server credential.
