IT companies have a lot at stake to leave the security of the data they work with at random. The protection of all this information is the key to the efficiency of its services. Backup and disaster recovery (DR) are the two most widespread security solutions, but in which scenarios should each of them be implemented? Knowing the differences between one and the other will serve to find the optimal alternative in each case.
How is backup different from disaster recovery?
Although these are two IT security solutions, in no case can they be treated as equals. While it is true that backup and disaster recovery are the essence of any data protection strategy in a company, it is convenient to know the differences between one and the other to manage them with the greatest efficiency for Dell PowerEdge T330.
Storage and data retention
The backup is a mere periodic copy of data or files while the recovery in case of disaster is the tool that, at critical moments, manages to put those copies into operation and take full advantage of the information stored safely.
In both cases we work with automated systems that try to maximize the storage capacity. But while one is limited to collecting information for eventual reinstatement, the other guarantees that no company suffers the consequences of a period of inactivity as a result of the loss of data.
The DR guarantees the continuity of the activity of a business with a very low RTO (Recovery Objective Time) and a well defined RPO (Recovery Objective Point). It is a practically immediate response to a crisis situation.
Backup copies allow the 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 backup copies, the collection and retention functions are developed in the environment of the original sources of the information. On the contrary, DR solutions require an independent environment for the treatment of the collected data.
In this sense, the confidentiality and privacy of the client are more 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. The disaster recovery implies the development of a much more complex recovery strategy that allows to act quickly, limit the downtime and avoid future interruptions.
The work with protection services oriented especially to multisede SMEs that have decided to migrate to the cloud . We are aware that the processing, storage, registration and recovery of data always involves 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 higher quality alternative than the other but an option that works more efficiently in the specific environment in which it is implemented. We help you find it.
