DRaaS or Disaster Recovery in the Cloud, which is better for my business?
More and more small and medium-sized businesses (SMEs) are migrating their data to the cloud. The reason is because they need to protect corporate information against unforeseen events. Any hiatus in IT services can be the end for SMEs, so
It is necessary to have a recovery plan in the face of human or natural disasters.

Although the offer of Disaster Recovery Solutions It is summarized in the traditional backup or backup, there are two different levels to support the IT service that They may look the same, but they are not.. This is the Disaster recovery as a service (DRaaS) and Disaster Recovery in the Cloud. In fact, it is common not to distinguish the fine line that separates both services.
DRaaS and Disaster Recovery in the Cloud: Different Concepts
The first difference is the concept.
Disaster Recovery in the Cloud, also known as
Cloud DR, is an IT security measure that consists of
back up files and, in general, of a company's data. For its part, the
DRaaS is an instant replica of the SME data center, covering the operational management of the company's applications..
Difference in operation
El
Cloud DR provides the company with a real-time backup to recover its data without problems. Its objective is basically
Protecting the company's priority files. DRaaS, on the other hand, guarantees a
IT service continuity of the company. SME applications, systems and services remain online without affecting business performance, despite the critical situation resulting from a fire, flood, earthquake or unexpected failure of the
hardwareSpecifically, DRaaS acts to avoid the impact of a possible interruption of corporate applications.
Are both equal in disaster recovery?
El
cloud DR It enables businesses to restore stored information efficiently and in an orderly manner, without resorting to cumbersome disaster recovery methods. It also allows employees to access data stored in the cloud. Its main advantages over a traditional solution are:
- Provides a complete disaster recovery system
- Savings in energy, technology and maintenance costs by being in the cloud
- Savings on software and hardware licenses
- Requires fewer operational resources
- Decreases RTO times (time during which the lack of operation of the applications can be tolerated) and RPO volume (acceptable amount of data loss) considerably
However, the company must have enough bandwidth to redirect its users to the cloud and a
contingency plan to restore data with limited resources, especially when the business must guarantee full-time service to customers.
DRaaS has the virtue of endorsing a comprehensive recovery, but not before quickly assuming the main commands, the computer assets and the IT security protocols. For this reason, among the disaster recovery solutions, DRaaS is gaining strength in SMEs for two reasons:
- la cost reduction in hardware and software licenses
- a increased responsiveness at critical times, without the need for an exorbitant budget to maintain stable and permanent operations
In conclusion, each SME or company must choose the solution that best suits its needs and idiosyncrasies. If a solution is offered to customers 24 hours a day, 365 days a year, it is very likely that a recovery system that does not react almost immediately to a malfunction or loss of information will not be tolerable. In these situations, cloud-based disaster recovery solutions are the best possible alternative.
