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.
Food for thought for another productive system: until when must the system be identical, keyword: transaction log
An SAP system copy is an important part of a company's IT operations, as it helps reduce the risk of data loss. However, it is important to regularly schedule and monitor the creation of system copies to ensure that a working copy of the system is available in the event of an emergency.
Typically, the "homogeneous SAP system copy" process involves a large number of manual activities. A certain skill level is required for this, which leads to the fact that usually the employees of the SAP Basis department or external service providers realize the system copy. Depending on the structure and size of the systems, this process can take anywhere from hours to several days. In addition to making the target systems unavailable to operations and project teams, system and landscape copies also block SAP Basis administrators. Other challenges include the varying duration and quality (completeness) of the results depending on the processor, time dependency on the employees performing the work, etc.
SAP system copy can be done easier and faster with "Shortcut for SAP Systems".
In addition, SAP suggests that you validate change transports through a QA system that is approximately identical to the production system and has up-to-date transaction data.
The third-party providers have adapted their tools to various special areas.
