Differentiation between homogeneous and heterogeneous SAP system copy
Create SAP HANA system replication levels
An SAP system copy is a process in which an exact copy of an existing SAP system is created. This copy can be used to run tests, perform development, or back up the system.
Different DDLORA* files can be assigned to the R3load packages. The assignment is done by a text file, which is given to the MigrationMonitor as parameter 'ddlMap = mapDDL.txt' and evaluated by it.
SAP system copies and the DSGVO
SAP offers its own solution for this: With the Test Data Migration Server (TDMS), individual tables can be selected and written indirectly, via a third SAP system, from the source to the target system via Remote Function Call (RFC). However, the selection of business objects is not possible in the standard system. The tables to be copied can only be determined on the basis of the date. The content restriction applies from a certain point in time. At least the SAP tool can be used to reduce the runtime of an extraction of test data compared to the system copy or client copy.
Homogeneous system copy: In this type of copy, the operating system and database on the target system are the same as on the source system. So Windows remains Windows and Linux remains Linux. And if the SAPHana database is running on the source system, it will also be used on the target system.
With "Shortcut for SAP Systems", tasks in the area of SAP system copy are simplified and made possible.
Landscape copies refer to the update of not only one but a whole group of systems.
However, the burden of copying falls on the SAN.
