FILE Backup in SQL Server Step by Step Tutorial with Examples

Using FILE backup one can backup SQL Server Data File individually. While backing up the database you can specify whole of FILEGROUP instead of specifying each database file individually within the FILEGROUP. In case if there is any file within the FILEGROUP OFFLINE may be because of file being restored then the whole FILEGROUP will be OFFLINE and cannot be backup up. A FILE backup can also serve as the differential base for differential file backups. For more information, see Differential Backups in SQL Server.

TSQL Script to Create Database with Multiple Data Files in Primary and Read Only File in Secondary File Group

USE [master]

CREATE DATABASE [MyTechMantra]
CONTAINMENT = PARTIAL
ON PRIMARY 
( 
NAME = N'MyTechMantra', 
FILENAME = N'F:\MSSQL\DATA\MyTechMantra.mdf', 
SIZE = 5120KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB 
), 
( 
NAME = N'MyTechMantra_Data2', 
FILENAME = N'F:\MSSQL\DATA\MyTechMantra_Data2.ndf', 
SIZE = 5120KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB 
), 
FILEGROUP [ReadOnly] 
( 
NAME = N'MyTechMantra_ReadOnly', 
FILENAME = N'F:\MSSQL\DATA\MyTechMantra_ReadOnly.ndf',
SIZE = 5120KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB 
)
LOG ON 
( 
NAME = N'MyTechMantra_log', 
FILENAME = N'F:\MSSQL\DATA\MyTechMantra_log.ldf', 
SIZE = 2048KB , MAXSIZE = 2048GB , FILEGROWTH = 10%
)
GO

TO DISK = N'C:\DBBackups\MyTechMantra_MyTechMantra_Data2.bck' 
WITH NOFORMAT, NOINIT, COMPRESSION, STATS = 25
GO
