What is cloud computing disaster
recovery?
Disaster recovery refers to the method and techniques employed by an organization to
retain and maintain access to and control of its IT infrastructure even after a disaster,
whether natural or cyberattack, including business disruptions caused by COVID-19. .
A disaster recovery plan is a crucial part of business continuity. You can use various
methods of disaster recovery (DR) to stay away from any disaster.
Disaster recovery uses data replication techniques and computer processing in a remote
data center that cannot be affected by the disaster. Whenever a disaster causes servers to
fail, such as a cyber attack or equipment failure, businesses need a secondary location to
recover lost data from a backup server.
Businesses can also move computing processing to a remote server to ensure 24-hour
availability and continue operations.
What is disaster recovery and its benefits?
No business should take the risk of ignoring disaster recovery techniques. The two most
essential benefits of a good disaster recovery plan include:
Quick recovery
A business can quickly resume operations after a disaster.
Cost savings
Disaster recovery can help companies save thousands, if not millions. Sometimes it also
determines whether a business survives a disaster or cannot recover and goes out of
business.
What are the different disaster recovery techniques?
There are many disaster recovery techniques that companies can choose from, or
combine several to create an ultimate solution:
Disaster Recovery as a Service
DRaaS providers migrate an organization's data and computing processing to their cloud
infrastructure. It enables businesses to continue operations seamlessly from the provider's
location, even if an organization's servers are down.
Back
This simple disaster recovery method focuses on storing data remotely or using a
removable disk. However, backing up your information hardly contributes to business
continuity because the network infrastructure remains intact.
Cold website
This type of disaster recovery involves setting up a basic business network infrastructure
at a secondary facility. Ensures that employees always have a workspace, even after a
deadly disaster. Cold sites contribute to business continuity by allowing operations to
continue. However, it lacks the provision to protect or recover sensitive data. Therefore,
you can combine this technique to develop a more effective disaster recovery strategy.
Hot website
A dynamic site maintains up-to-date copies of data and files around the clock. However,
setting up a warm site can be time consuming and more expensive than cold sites.
However, it drastically reduces downtime.
Instant recovery
Instant Recovery works like point-in-time copies. However, instant restore backs up the
entire virtual machine instead of just backing up a database.
Backup as a service
Like remote data backup, backup as a service is the provision of backup storage to
businesses by a third-party provider.
Virtualization
Businesses can back up select operations or replicate an entire computing environment
to virtual machines in the cloud, safe from physical disasters in the data center. Allows
the automation of recovery processes and restore functions faster.
Data Center Disaster Recovery
Physical protection of a data center can preserve and improve disaster recovery in the
cloud during specific disasters. Some of these techniques include fire extinguishers,
which prevent the loss of data and infrastructure in the event of a fire. In addition,
emergency power supplies guarantee availability even in the event of a power failure.
Spot copies
Point-in-time copies/snapshots are backup files of an organization's database made at
specified intervals. Users can restore data using shared copies if they are offsite or
unaffected by the disaster.
Develop an effective disaster recovery plan
Get a disaster recovery team: Companies should appoint specialists to create, manage and implement disaster recovery
plans. An effective recovery plan carefully defines the roles and responsibilities of team
members. It also outlines the proper communication channels for the recovery team,
vendors, employees, and customers.
Identify critical business assets: An effective disaster recovery plan includes detailed documentation of all critical
resources, applications, systems, and data, including recovery steps.
Backups: Companies need to determine in advance what data needs to be backed up
and make sure people explicitly back it up. An effective backup includes a recovery
point objective (RPO) to delineate the frequency of backups and a recovery time
objective (RTO) to define the maximum downtime.
Testing and Optimization: An enterprise's data recovery team must perform continuous
testing and strategic upgrades to keep up with changing threats and business needs.
This can help ensure that an organization stands strong in the face of disasters.
It is crucial that organizations continually test and optimize data protection strategies.
Risk Assessment: Businesses must carefully assess the potential risks they may face.
There must be a strategy to determine the actions and resources needed to resume
operations in the event of an attack or disaster.
Disaster recovery and business continuity planning
A network outage can significantly affect business operations, especially with the
current pandemic in effect. Your plan should include people and not just focus on
technology. The pandemic has affirmed that business teams need the right support and
resources for effective productivity. Make sure you have a solid strategy in place to
deliver this to all employees, and even more so to remote workers.
You can also include additional cloud solutions, software as a service, to increase
efficiency and improve flexibility. It also reduces the burden of relying on a single data
center. You can add infectious diseases and potential risks to your company's disaster
recovery plan. An effective strategy for such an emergency can help ensure things run
smoothly without affecting business operations.
