Backup or Disaster Recovery? Keys to security in the IT environment
IT companies have too much at stake to leave the security of the data they work with to chance.
Protecting all this information is the key to efficiency of its services. The backup and the
disaster recovery (DR) are the two most widely used security solutions, but in which scenarios should each of them be implemented? Knowing the differences between them will help you find the optimal alternative in each case.

How is backup different from disaster recovery?
Although they are two IT security solutions, they cannot be treated as equals in any case. While it is true that the
Backup and
disaster recovery They are the essence of any data protection strategy in a company, it is important to know the differences between them in order to manage them with the greatest efficiency.
Data storage and retention
El
backup is a mere periodic copy of data or files, while disaster recovery is the tool that, at critical moments, manages to put those copies into operation and take real advantage of the information stored safely. In both cases, automated systems are used to try to maximize storage capacity. But while
One merely collects information for eventual reinstatement, the other ensures that no company suffers the consequences of a period of inactivity. as a result of data loss.
Resiliency
The DR guarantees the continuity of a business's activity with a
RTO (Objective Recovery Time) very low and a
RPO (Recovery Objective Point) is a well-defined, almost immediate response to a crisis situation. Backups allow for effective restoration of essential data, but do not facilitate automatic failover in the event of a system failure.
Confidentiality, security and privacy
When working with backups, the collection and retention functions are performed in the environment of the original sources of the information. In contrast,
DR solutions require a separate environment for the processing of the data collected. In this sense, the client's confidentiality and privacy are better protected since data backup does not require frequent access to their servers.
Strategy and planning
The
Backup routines are much simpler since you only have to establish an RPO and a data retention standard. Disaster recovery involves the development of a much more complex recovery strategy that allows you to act quickly, limit downtime and avoid future interruptions. At apser we work with protection services aimed especially at multi-site SMEs that have decided to
migrate to the cloud. We are aware that data processing, storage, recording and retrieval always entails certain risks. Precisely for this reason, all businesses must have IT security services adapted to the particularities of their activity. In this sense, there is no alternative of higher quality than the other, but rather an option that works more efficiently in the specific environment in which it is implemented. We help you find it.
