Scenario with system copies for updating
Companies with backup systems can use these for a client copy and thus save on the computing power of the productive system. However, the burden of copying falls on the SAN. Because the reliability is limited by the misuse of the backup system and the storage network is additionally burdened, users should keep the runtime of this refresh variant as short as possible.
The database import can be performed using various tools. Sapinstaller provides a working way to import the database cleanly.

Partial copies from SAP systems with the help of tools open up potential savings and in many cases make system copies and complete client copies superfluous. The ability to anonymize data reduces the effort required to comply with data protection regulations in training systems, for example. In addition, up-to-date, consistent test data improves the flexibility and quality of development and test environments. Users save money through reduced resource requirements.
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.
Tools such as "Shortcut for SAP Systems" are extremely useful in SAP system copy.
With the entry into force of the GDPR, the topic of system copies has been expanded to include the aspect of anonymization: In many cases, personal or other sensitive data is operated on non-productive systems that usually have lower security levels and also allow access for those persons who are not normally allowed to work with GDPR-relevant data (eg developers or external consultants).
