Stripping Database backup to multiple files and on different drives will make the backup speed faster and will reduce the backup duration.

Check the below sample script for the backup and restore. You can perform the same task using SSMS GUI as well.
Backup Script

BACKUP DATABASE [SQLDBPool] TO  
DISK = N'C:\JSpace\Backup\SQLDBPool1.bak',  
DISK = N'C:\JSpace\Backup\SQLDBPool2.bak',  
DISK = N'C:\JSpace\Backup\SQLDBPool3.bak'
WITH NOFORMAT, 
NOINIT,  
NAME = N'SQLDBPool-Full Database Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10
GO

Restore Script

RESTORE DATABASE [SQLDBPool] FROM  
DISK = N'C:\JSpace\Backup\SQLDBPool1.bak',  
DISK = N'C:\JSpace\Backup\SQLDBPool2.bak',  
DISK = N'C:\JSpace\Backup\SQLDBPool3.bak'
