How to back up a single database in SQL Server?

To back up a single database in SQL Server, you can use SQL Server Management Studio (SSMS) or T-SQL commands. Here's how to do it:

Method 1: Using SQL Server Management Studio (SSMS)

1. Open SSMS and connect to your SQL Server instance.
2. In the Object Explorer, expand the "Databases" node.
3. Right-click the database you want to back up, then select "Tasks" > "Back Up...".
4. In the "Back Up Database" dialog:
   • Ensure the "Database" field shows the correct database name.
   • Set the "Backup type" (Full, Differential, or Transaction Log).
   • Choose a destination for the backup file (click "Add..." to specify a new path).
5. Click "OK" to start the backup.

Method 2: Using T-SQL Commands

You can use the BACKUP DATABASE command to back up a single database. Example:

BACKUP DATABASE [YourDatabaseName]
TO DISK = 'C:\Backups\YourDatabaseName.bak'
WITH INIT, STATS = 10;

• Replace [YourDatabaseName] with your actual database name.
• TO DISK specifies the backup file location.
• WITH INIT overwrites the backup file if it exists (use WITH NOINIT to append).
• STATS = 10 shows progress every 10%.

Example Scenario

If you have a database named SalesDB, you can back it up using:

BACKUP DATABASE [SalesDB]
TO DISK = 'D:\SQLBackups\SalesDB_Full.bak'
WITH INIT;
