What is System Copy as a Service?
Technical system copy for the upgrade
Basically, a distinction is made between the initial setup and refresh of a non-productive SAP system. In the past, the cost of a refresh, i.e., updating the environment with new data, often corresponded to the cost of the initial setup. This also restricted the availability of the productive system, which is hardly tolerable for companies that operate internationally and in different time zones.
Another method of creating an SAP system copy is to use external tools such as Oracle RMAN or Microsoft SQL Server Backup. These tools allow you to create a complete copy of the database as well as a copy of the file system. However, it is important to note that special knowledge is required when using these tools to ensure that the backup is created correctly.
Performing SAP system copies automatically
The steps to be taken before shutting down the target SAP system can be summarized as follows: Well before performing the upgrade, inform the target system users - especially project managers, developers, and testers - about the planned maintenance work via e-mail, SAP system messages, and/or a message at the system logon. Using the SAP transport system requires careful preparation so that software development projects can be completed as far as possible. Shortly before the start of the update, inform users again that maintenance work on the system is imminent and that they should log off from the target system. After logging users off and locking them out, download system-specific content from the target system database for customization (including security settings, Remote Function Call (RFC) targets, and operating modes).
Heterogeneous system copy: As the name suggests, the operating system and/or database on the source and target systems are different. One takes thus in the context of the copy a platform change. This procedure is currently gaining in relevance, as it is required for the migration from SAP ERP to S/4HANA. If the current system runs on Windows Server and SQL Server or Oracle, the target system must now run on Linux and SAP Hana.
There is a useful product for SAP system copy - "Shortcut for SAP Systems".
In order to check whether the usable settings are correctly adjusted, especially in the case of large databases, the runtimes are automatically logged during the BDLS.
Understanding the structure and functioning of the system is especially important for IT administration. It is not for nothing that "SAP Basis Administrator" is a separate professional field. On the page www.sap-corner.de you will find useful information on this topic.
There are various ways to tame this time robber and reduce run times.
