Efficient options for SAP system copies
While homogeneous SAP system copy expects identical combinations of operating/database systems on the source and target systems, there is also a requirement for different combinations of operating/database systems on the source and target systems in the project environment (eg, during migrations). This is referred to as a "heterogeneous SAP system copy". Technically, it is quite possible to build up a degree of automation here as well, but officially certified consultants ("migration consultants") are required to perform the heterogeneous system copy.
Increasingly, ad hoc requests are coming from IT or SAP Basis to provide an SAP system copy as quickly as possible, for example of an SAP ERP, BW or HCM system. This often leads to special challenges due to a lack of resources or capacities.
Multicloud: the systems involved with different hyperscalers
A SAN enables a system copy during dialog operation. In this way, virtual copies of a logical volume, so-called snapshots, can be created. Data is only copied if it is changed in the original data volume (copy-on-write procedure). When copying from a snapshot to file level, the affected systems remain available. However, this procedure puts a strain on the storage network. If this takes several days, the response times of the productive system deteriorate.
The website www.sap-corner.de offers many useful information about SAP basis.
Database: For some databases (MS SQL Server) there is the possibility to copy the database files and reattach them on the target system. For the following SAP installation you only have to specify that no SAP loads should be used, but that the database is already there!
With "Shortcut for SAP Systems", a mature and yet very cost-effective product is available that offers useful functions for system copies. For example, SAP system users can be backed up and restored. Likewise, system-specific tables can be backed up before the system copy and restored after the system copy. And all this can also be automated.
Based on these results, it is possible to analyze how the runtime can be further optimized.
Quasi tick boxes instead of time-consuming handling of programming lines, so that the use is also possible for less experienced experts who have never or only few SAP system copies created.
