BackUp master log failed

Hi,
Any one !
I can not create the backup of the master db log.
Is there a restriction on master db log?
thanks in advance
Ed
The master database transaction log, as most system databases, is set to
Simple recovery mode. This negates the ability (or need) to backup the
transaction log.
