Is it possible to create a global stored procedure at Sql server level

I created a query that takes a database backup at certain specified location.
I want to use it as a stored procedure but this should act as a global stored procedure so that whenever this SP is called. Then database backup is taken.

It uses DB_Name() to take database backup of owner database.

Is it possible to create any such SP or Function.

I am using sql server 2005


first solution:

If you create your sp in the master database and mark it as a system object and prefix it with ‘sp_’ then a single copy will exist that will be shared by all databases.

and second solution from msdn:

Private and global temporary stored procedures, analogous to temporary tables, can be created with the # and ## prefixes added to the procedure name. # denotes a local temporary stored procedure; ## denotes a global temporary stored procedure. These procedures do not exist after SQL Server is shut down.

an example :

    USE master
    CREATE TABLE test (c1 VARCHAR(50))
    INSERT test VALUES('master')
    CREATE PROC sp_test AS
    SELECT * FROM test

USE northwind
    CREATE TABLE test (c1 VARCHAR(50))
    INSERT test VALUES('northwind')

USE pubs
    CREATE TABLE test(c1 VARCHAR(50))
    INSERT test VALUES('pubs')

USE pubs
    EXEC sp_test --returns 'master'

USE master
    EXEC sp_MS_marksystemobject sp_test

USE pubs
    EXEC sp_test --returns 'pubs'

USE northwind
    EXEC sp_test --returns 'northwind'
