What Is Cloud-Based Disaster Recovery?
Cloud-based disaster recovery is a service offered by third-party cloud providers that ensure your company’s business continuity by replicating your systems and data to public or private cloud infrastructure and managing the failover and failover process. Recovery when a disaster occurs. Cloud-based disaster recovery is also called disaster recovery as a service (DRaaS).
What Is a Local Dr (On-Premise) Like?
Local disaster recovery refers to a solution where your secondary disaster recovery systems are located where your production systems are. This can be an expensive option because it requires your organization to:
Hire IT and technical staff to develop, test, and execute your disaster recovery strategy.
Back up your systems and data and keep these backups in an on-site data center, stored disk, or tape.
Invest in hardware, software, maintenance, and support for hardware and software.
Advantages of Cloud-Based Disaster Recovery
Cloud-based disaster recovery can help your organization minimize downtime and data loss to ensure business continuity, reduce disaster recovery costs, and help you meet regulatory requirements.
Whether it’s a flood, hurricane, tornado, fire, cyber attack, or artificial disaster that destroys or brings down your production systems, downtime can bankrupt your business.
With cloud-based disaster recovery, the cloud provider replicates your systems and data to a cloud infrastructure at least 150 miles away from your production systems. This geographic distance is vital to minimize the chance of the same disaster impacting your production systems and cloud-based disaster recovery site.
When a disaster strikes your production systems, the cloud provider performs disaster recovery orchestration: switching production systems to the cloud-based disaster recovery site and back to the leading site once the IT infrastructure is back in place. The cloud provider ensures that your organization achieves agreed recovery point objectives (RPOs) and recovery time objectives (RTOs).
Lower DR costs
With cloud-based disaster recovery, you can reduce costs and enjoy peace of mind because:
Smaller businesses can eliminate the need to hire DR experts to manage local DR.
Larger IT teams can focus on core operations rather than disaster recovery planning, testing, and executing.
The cloud provider will arrange backup, failover, and failback services and keep your backups in a safe and secure data center.
You will not need to invest in purchasing and maintaining duplicate hardware or software.
Cloud vs. on-premises disaster recovery
While cloud-based DR can mitigate downtime, reduce DR costs, and enable compliance, on-premises DR also has some advantages :
Minimize data loss, as local disaster recovery replicates data in near real-time over a local area network (LAN) instead of a slower Internet connection to replicate data to a remote infrastructure. Cloud.
Reduce latency when disaster strikes or when you need to recover selected files/folders. Accessing a local system over a LAN is faster than navigating an Internet connection to access a cloud infrastructure.
Predict the ongoing costs of an on-premises DR solution more accurately, as cloud-based DR costs will increase when a disaster strikes and your organization actively accesses cloud infrastructure for day-to-day operations.
