SQL Server Backup and Restore - Simple Talk

Chapter 9: File and Filegroup Backup and Restore
USE [DatabaseForFileBackups_SB]
GO
INSERT INTO Table_DF2
VALUES ( 'This is the third data load for Table_DF2' )
GO
Listing 9-26: Third data load for DatabaseForFileBackups_SB.
Now we're going to simulate a problem with our secondary data file which takes it
(and our database) offline; in Listing 9-27 we take the database offline. Having done so,
navigate to the C:\SQLData\Chapter9 folder and delete the secondary data file!
-- Take DatabaseForFileBackups_SB offline
USE master
GO
ALTER DATABASE [DatabaseForFileBackups_SB] SET OFFLINE;
GO
/*Now delete DatabaseForFileBackups_SB_Data2.ndf!*/
Listing 9-27: Take DatabaseForFileBackups_SB offline and delete secondary data file!
Scary stuff! Next, let's attempt to bring our database back online.
USE master
GO
ALTER DATABASE [DatabaseForFileBackups_SB] SET ONLINE;
GO
