Hi Guys,

thank you!
I do not have SQL server Agent and standard SQL edition.

This code:
declare @cmd varchar(5000)
select @cmd ='if ''tempdb'' <> cast(''?'' as nvarchar) backup database [?] to disk =''x:\sql_backup\?\?_2017_06_15.bak'''
PRINT @cmd
exec sp_msforeachdb @cmd 


is for SQL Server Agent or cmd task ? 

Best Wishes,
Jacek
