If you asked to any developer about how to take database backup, they will generally reply - its very easy. Just use SQL server backup window or use the ready-made script.

But if you asked them take the backup of 20 GB database and upload on some different machine?
If you are making a single heavy backup file with 20GB and try to upload on FTP server then it might take hours. By any chance, this upload operation truncate in between then again you have to waste your time by uploading the same file on FTP server as well as you have monitor them now.

Is there any better way?

Yes. SQL server provide a way where you can split single database into multiple smaller file. Let suppose you have 20 GB database and now you can take backup in 10 different files and each file having 2 GB in size.

Here are other advantages of splitting database into multiple files

  • Store each file in different drive or locations.
  • ZIP individual file 
  •  Upload individual file on FTP location

Here is a sample script for backup database in 3 different files at three different locations.

BACKUP DATABASE SitecoreLessonsSitecore_Master
TO DISK = 'D:\Backup\SitecoreLessonsSitecore_Master\1.bak',
   DISK = 'C:\Other_Drive_Backup\SitecoreLessonsSitecore_Master\2.bak',
   DISK = 'E:\Daily_Backup\SitecoreLessonsSitecore_Master\3.bak'

Note:- Folder path must exist for successful backup operation.

Use below query to restore these files

RESTORE DATABASE [SitecoreLessonsSitecore_Master_Staging]
FROM DISK = N'D:\Backup\SitecoreLessonsSitecore_Master\1.bak',
     DISK = N'D:\Backup\SitecoreLessonsSitecore_Master\2.bak',
     DISK = N'D:\Backup\SitecoreLessonsSitecore_Master\3.bak'

Note:- Restore work on server where this database is not exist.

You can backup and restore by using SQL server management studio also. Here is a reference link for it

I have used this backup script multiple times.
