In this context, generated jobs adapt to changes, even if, for example, a DB change, a release change or other changes have taken place. Nevertheless, once created copy jobs can be reused, which minimizes the maintenance effort and a certain susceptibility to errors. This is also the case when switching from one Any DB to another or when moving from an Any DB to Hana.
The solution described in this document can be summarized as follows: The goal is to create a homogeneous copy of an SAP system. The source of the system copy is a production system. The target of the system copy is an existing non-production system. The focus is on a specific use case, a system copy created for updates. Backup and restore are performed at the SAN device level and supported by HP System Copy software. Pre- and post-processing is automated using the UC4 Automated System Copy for SAP solution. Thus, the proposed solution allows you to optimize the automation and acceleration of SAP system copies generated for upgrades and reduce IT administration costs. Automated, fast and powerful upgrade capabilities enable shorter and more flexible SAP software lifecycles, enabling more agile business processes.

Creating a consistent storage replica - splitting a clone or creating a snapshot on the disk array. Regardless of the storage size, this process takes only a few seconds.
A solution such as "Shortcut for SAP Systems" offers an automatable solution for many of the activities involved in an SAP system copy.
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).
SAP Basis refers to the administration of SAP system that includes activities like installation and configuration, load balancing, and performance of SAP applications running on Java stack and SAP ABAP.

So much information... how can you keep it so that you can find it again when you need it? Scribble Papers is a "note box" that makes this very easy.
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.
