Disaster Recovery Services
The DRaaS (disaster recovery as a service) model can save organizations money as it eliminates the need to provision and maintains their own disaster recovery environment off-site. Getting the Disaster Recovery Services help you need in the event of a disaster is something every business should consider.
DRaaS (disaster recovery as a service) is a cloud computing service model in which organizations can back up their data and IT infrastructure in a third-party cloud environment using a cloud computing service model. The SaaS solution provides all the disaster recovery orchestration necessary to regain access and functionality to IT infrastructure after a disaster. By using the as-a-service model, the organization isn't responsible for owning all the resources or overseeing disaster recovery but instead relies on a service provider to take care of everything.
Planning for disaster recovery is essential for business continuity. Recent years have seen an increase in the number of disasters that threaten IT organizations. Like,
- Disasters caused by natural events such as hurricanes, floods, wildfires, and earthquakes
- Power outages, equipment failures, and cyberattacks
Disaster Recovery as a Service (DRaaS) Operating Models
Managed DRaaS: Disaster recovery is handled entirely by third parties under the managed DRaaS model. Organizations that choose DRaaS should work closely with providers to stay on top of all changes to their infrastructure, applications, and services. A disaster recovery service is a great option for those with less time and expertise.
Assisted DRaaS: A supported DRaaS may be a better option if you are interested in taking control of certain disaster recovery aspects or if you have custom applications that are difficult to handle by a third party. Disaster recovery plans are created and implemented by the customer in this model. The service provider provides services and expertise to optimize disaster recovery processes.
Self-Service DRaaS: Self-service DRaaS is the cheapest option, where the customer plans, tests, and manages disaster recovery, while the vendor hosts backups and virtual machines remotely. All major cloud providers offer this model, including Amazon, Microsoft Azure and Google Cloud.
The vendor's remote data center is to be used as a failover point as soon as local resources are restored, and the recovery process is to be carried out with careful planning and testing. If an organization has disaster recovery expertise in-house and has experience with cloud computing, this option is a good fit.

What is Disaster Recovery as a Service?
Disaster Recovery as a Service (DRaaS) is disaster recovery hosted by a third party. Business continuity services involve replicating and hosting physical or virtual servers to provide failover in case of natural disasters, power outages, or other crises.
According to DRaaS, a remote vendor, which typically has a globally distributed architecture, is less likely to be impacted by a natural disaster than its customer. It allows the vendor to support customers in the worst-case disaster recovery scenario, in which an organization's physical facilities or computing resources will be completely shut down due to a disaster.
On-premises or cloud computing environments can be failed over using third-party DRaaS vendors, who can bill based on actual usage or on an ongoing retainer basis. Service level agreements (SLAs) typically outline DRaaS requirements and expectations.
DRaaS vs. backup as a service (BaaS)?
During a disaster, disaster recovery as a service moves an organization's computer processing to the cloud. It is possible to continue to operate even after the original IT infrastructure has been completely destroyed or is held hostage in this way. Unlike backup as a service, when only the data is replicated by a third-party provider, not the ability to process it. DRaaS is usually more expensive than BaaS because it is only protecting the data and not the infrastructure. For businesses that are required to archive records or data for legal reasons, BaaS can be a good solution, but most use it in conjunction with another disaster recovery tool to ensure continuity.
Is DRaaS Really Just Data Backup?
DRaaS includes data backup as one of its components. You can store and synchronize backup copies of data online using backup-as-a-service (BaaS). By using these services, you can ensure that data lost or ransomed from one site is kept intact elsewhere and still accessible when you need it. However, they do not help with the recovery from a disaster. Cloud-based DRaaS moves your entire IT stack to the cloud, including infrastructure, applications, data, computer processing, and networking. During an outage, your company gets a fully mirrored backup system in place so that it can continue operations without interruption.
How Cloud DR Works?
A cloud management interface supplied by your provider enables your IT team to back up the virtual machines (VMs) and physical servers in your IT infrastructure. As part of the DRaaS service, backups of your selected servers are regularly taken at your IT location(s) in the background, ready for recovery in the event of a failure.
As a general rule, your primary data center and cloud disaster recovery sites will share synchronized data to store snapshots and applications. In the event of an outage, VMs need to be brought online during failover, and usage fees usually only apply when a server is accessed.
As a result, you don't have to own all the equipment that's needed to build a fully replicated IT stack that's rarely used. In order to restore data, apps, and infrastructure as quickly as possible, the DRaaS provider plans and automates all the processes.
What are the steps for testing a disaster recovery plan (DRP)?
There are five ways to test your corporate disaster recovery plan:
- Paper Testing: This involves reviewing backup documentation and planning
- Walkthrough Testing: The backup team walks through what to do after being hacked or infected by ransomware
- Simulation Testing: Testing team response and potential downtime by simulating a problem on test servers
- Parallel Testing: Before pushing 'fixes' to production servers, tests are run on backup servers to simulate the problem
- Disaster Recovery Testing: During simulated attacks or data breaches, systems are switched to backups
