Hi,

I have installed NW7.3 EHP1 with Sybase database 15.7.0.12,I have performed the backup through Stored procedure and also tried backing up the database with Sybase Central,both were successfull

Now I wanted to perform the backup's through DBACOCKPIT,please let me know if there is any guide which tell me how to achieve this
