Disaster recovery (also known as DR) refers to the process of restoring IT systems and services after a failure or other unforeseen event. The goal of disaster recovery is to ensure that a company or organization can quickly return to its normal business operations after a failure.
In this specific case, a supposedly simple change in invoice reporting led to serious subsequent errors. In fact, the previous invoice profiles were only supposed to be mapped in more detail due to new requirements.
From the perspective of the affected system, this changeover was transparent and could be solved by simple data migration. However, the effects on the downstream chain interfaces of the connected systems were serious, as the format changes to the interfaces that were transparent within IRP could temporarily no longer be processed automatically. It was also no longer possible to roll back to the previous keys, meaning that a massive data imbalance was created in a very short time before the problem was identified.
As the disaster recovery team, we were able to identify the approach to the solution and provide significant support for the rescue clean-up. The fact that "set theory" had to be used as a mathematical procedure as a rescue method shows once again that even supposedly superfluous school education can have practical benefits.
With the By restarting interrupted digital process chains and restoring the key relationships of data structures, we were ultimately able to successfully eliminate structural differences.
What is disaster recovery?
Disaster recovery (also known as DR) refers to the process of restoring IT systems and services following a failure or other unforeseen event.
A disaster can have various causes, such as natural disasters, human error, power outages, cyber-attacks or other unforeseen events. To protect against these risks, companies and organizations use various technologies and processes to speed up the recovery of IT systems and services.
Typical components of disaster recovery include:
- Data backup and restoration: Backup copies of the data are created and restored if necessary.
- High availability: Redundancy of hardware and network components to avoid or minimize failures.
- Disaster recovery: A predefined process to quickly restore systems and services.
- Test and review procedures: Regular testing of disaster recovery plans to ensure they are effective and updated.
Overall, disaster recovery is an important part of the IT infrastructure of companies and organizations, as it enables them to ensure business continuity even after unforeseen events and thus minimize potential financial losses or reputational damage.
