Back-up is based on saving a copy of the current state of the machine. This is usually done with a certain periodicity to guarantee the least possible loss of data and services.
Once the backup is created, it is typically sent to another system to minimize the risk of losing them, generally to a server expressly dedicated to this functionality.
Data replication is based on two synchronized servers in real time and maintains an identical state. This allows us a much more immediate response to specific incidents.
Although replication is a much more expensive method, since it requires two or more servers, it provides an almost quick reaction when the primary server is down.

Since the new General Data Protection Regulation came into force, more and more different companies and organizations have shown their need to protect their information and grant privacy to the corresponding data.
Added to all this is the concern to preserve knowledge through social networks and comply with the large number of regulations emerging regionally and statewide.
The impact of this regulation is more than evident in organizations, and the increased requirements regarding data protection give rise to more comprehensive approaches, such as disaster recovery.
Establishing backups for your information is vital for the continuity of your business. The reality of cybersecurity is that even with adequate perimeter security, the risk of data hijacking or encryption attacks is always latent. Intelligent backup solutions allow you to have a rescue plan in a disaster.
Data replication solutions allow you to copy and keep data updated in different notes, offering special data protection for your business information systems and allowing you to recover points immediately before the physical or virtual disaster your storage may suffer.
The advantage of replication over backup is that recovery times are much faster. Of course, the disadvantage of image compared to backup is that it is not a solution that protects against viruses, corruptions or losses.
Being simply a replica, it replicates the entire server as it is; if it has viruses, corrupted files or has suffered losses as will copy it. In addition, there is no possibility of recovering histories.
The main benefit of backup over replication is that by locating that copy on a device other than the original if it suffers an incident, we are guaranteed to have an optimal duplicate previously made on an independent array.
This is essential as a ransomware cybersecurity solution. In addition, it is possible to store as much history as needed while adding new backups.
The continuity of your business depends on having a good disaster recovery plan that includes solutions that allow you to restore data, hardware and software.
Today there are disaster recovery solutions capable of executing rapid recovery to points immediately before the disaster or encryption.
