Saving SQL Server backup file in multiple parts I am taking daily backups of a SQL Server database. Right now the .bak file is about 2GB and it is growing day by day. There is a scheduled job is running which moves this .bak file from one location to another. 

Is there a way to save the .bak file in chunks - like part1.bak, part2.bak etc..

so it will be much easier to move small data and merge at destination?
Normal backup 

SET STATISTICS IO ON

SET STATISTICS TIME ON

BACKUP DATABASE DBNAME
TO DISK = 'D:\DBNAME.bak'

SET STATISTICS IO OFF

SET STATISTICS TIME OFF


to split the size into 3 use the following code, it will split the size of 3 gb into 1 GB each file
you can add more files or less depending on the size you want 

SET STATISTICS IO ON

SET STATISTICS TIME ON


BACKUP DATABASE DBNAME TO

DISK = 'D:\DBBackups\ReportServer\DBNAME _Split1.bak'

,DISK = 'D:\DBBackups\ReportServer\DBNAME _Split2.bak'

,DISK = 'D:\DBBackups\ReportServer\DBNAME _Split3.bak'


SET STATISTICS IO OFF

SET STATISTICS TIME OFF
