The BACKUP DATABASE
statement is used in SQL Server to create a backup of one or more databases. It allows you to create full database backups, differential backups, or transaction log backups, depending on the options you specify.
Here's a basic example of how to use the BACKUP DATABASE
statement to create a full database backup:
BACKUP DATABASE YourDatabaseName
TO Disk = 'C:\Backup\YourDatabaseName.bak'
WITH INIT, FORMAT, STATS = 10;
Explanation of the options used in the BACKUP DATABASE
statement:
YourDatabaseName
: Replace this with the name of the database you want to back up.TO Disk = 'C:\Backup\YourDatabaseName.bak'
: Specifies the location and filename of the backup file. Adjust the path and filename as needed.WITH INIT
: Specifies that the backup should overwrite any existing backup sets. Be cautious when using this option, as it will overwrite existing backups without confirmation.WITH FORMAT
: Specifies that the backup operation should initialize the backup media, which is typically a disk file. This option is necessary when you're creating a new backup set.STATS = 10
: Specifies that backup progress information should be displayed every 10 percent. You can adjust the value as needed.It's important to note that the BACKUP DATABASE
statement requires appropriate permissions. Typically, only members of the sysadmin
fixed server role or the db_owner
fixed database role can execute this statement.
