Backup is not replication and replication is not DR

Quite a few people tend to confuse the concepts, so what is the difference between them and for what use is each suitable?!

Replication:
In computer systems, replication is the duplication of data or resources to ensure availability and performance. Replication is usually performed by third-party software, such as the VEEAM backup and replication system,
Replication is performed between two different devices, often across different locations, in order to ensure the survival of the information in case the main device is disabled.
The replication process involves creating copies of data or systems, for real-time synchronization. However, replication alone is not a comprehensive disaster recovery (DR) strategy.

Disaster Recovery (DR):
DR includes a broader strategy than replication to ensure business continuity after a disaster. The communication issue plays a crucial role in DR by assisting in the smooth transfer of data between primary and backup systems and connecting the organization's users to the DR environment. A well-designed network ensures fast data recovery, minimizing downtime and maintaining operational integrity.

backup:
Backup includes creating copies of data for long-term storage and recovery in the event of data loss or damage. While a communications network is not the primary focus of backup processes, effective network connectivity is essential to securely transfer and store backup data.
There are a large number of backup software such as Acronis as well as regular methodologies, which should secure the information in the event of a disaster.
Backup must be done in at least two circuits, a local backup and a backup outside the organization, in order to ensure that the information is saved in the event of a catastrophic event (fire, flood, earthquake, etc.).
In the event of an incident, with an emphasis on a cyber incident, the information will be restored to a "clean" environment that will be established.
Backup is the necessary solution for the protection of the organizational information.

In conclusion: Each solution stands on its own. Organizations that are interested in a quick recovery time will set up a DR site. Regarding backup, this is mandatory for every small and large organization.
