Online DB2 database Copy via backup/restore

Question

Hi Guru's
I am new in the world of DB2 (I am always working with Oracle)
I have to perform an online database copy of our SAP which is running on DB2, but I do not want to use the SAPinst method
I just want to perform it through the backup/restore method as I always do with oracle databases
Which procedure do I have to follow on my source and target SIDs
Regards
Richard
