Tran Log/Differential/File group Backups can not take for Master Database

Only full database backups of master database can be performed. Transactional log, differential or filegroup backups of master are not allowed. Thus if you create a Database Maintenance Plan for all the system databases or if you select the master database and you select the Back up the transaction log as part of the maintenance plan option, the backup transaction log step for the master database will fail with the error message.
