The practise of disaster recovery was developed in mid to late 1970’s, by a computer center manager who began to recognize depending organizations on their computer systems. At that time most mainframe systems could go down for many days.
Disaster recovery in information technology is a component of security planning and is developed in conjunction with business continuity planning. Disaster recovery may be a set of policies and procedures which specialize in protecting a corporation from any significant effects just in case of a negative event, which can include cyberattacks, natural disasters, or building or Hardware failures.
Why do we need IT environment disaster recovery?
In the IT industry, we have come across many instances of data loss and catastrophic failure, which leads to downtime and loss of business internally and externally. If this is one of our previous challenges in your case you should definitely think about your disaster recovery plan.
It’s an IT team job to prepare for the unexpected in its IT systems, from weather-related outages, security breaches, and even the small disruptions from power outages to networks issues and equipment failures can impact your IT systems and ultimately your customers
Any disruption of service may be an inconvenience to both employees and customers, but if systems are down and vital operation ceases, the consequences could be catastrophic to your reputation or the organization.
When a disaster strikes, businesses need to have a disaster recovery plan in place to successfully failover business-critical systems and data. However, due to resource constraints and budget constraints, many SME businesses find it difficult to design, onboard, and maintain a physical disaster recovery (DR) environment. This is where companies look at setting DR on the cloud with minimal cost. We at E2E networks offer affordable cloud servers in Indian data center. E2E has helped a lot of SME IT Companies with the Affordable cloud servers.
Define your own disaster recovery strategy:
No business is invulnerable to IT disasters, but a speedy recovery from a well-crafted IT disaster recovery plan is expected by today’s ever-demanding customers and the availability of cloud players in the market.
Always specify your tolerance for downtime and data loss
The IT team needs to plan its strategy for a disaster recovery plan: save money, save your customers, and save your business.
The first and foremost important thing IT teams need to do is define your RTO and RPO and define your business application impact analysis when Disaster happens.
Recovery Time Objective (RTO): Interval of time, that your application goes offline.
Recovery Point Objective (RPO): Last point of Data that can be restored.
If we need to lower the values of RTO and RPO, then the cost of running the application will be higher.
Questions your IT team should consider:
How much time am I prepared to have my mission-critical functions unavailable (RTO)?
How much information am I prepared to lose, i.e. the time duration for which you will not be able to recover your data (RPO). For example, if you safely back up your data once a day, you can lose up to one day of data when a disaster happens.
How much money will it cost the organization, when the mission-critical services are not available?
DR measures include prevention, detection, and correction.
One of the important best practices in DR is creating a frequent backup of your data. In the event of a disaster, you would then be able to reestablish your reinforcement and relaunch your strategic capacities and different administrations.
Backup and Restore:
Active passive (Warm Standby)
Active replicated (Hot standby - Multisite)
You could choose to use the extra resources in a second data center to make optimal use of DR investments, even when there is no failover due to a large disaster in the primary data center location. You can spread workloads between both the data centers, for example, with half of the workloads running in each data center. During a disaster, non-mission-critical services can be stopped for cost optimization.
Another example is when all systems are running in the primary data center and only those programs and data related to mission-critical functions are transferred — and are failed in the event of a disaster — to a second data center.
While carrying out business continuity planning, each company should have its own approach to disaster recovery as each business is different.
IT teams’ AIM should be clear to everyone — spend upfront to prevent higher costs of recovery in the event of a disaster.
Hope you will get a fair idea why companies should have DR in place. We at E2E Networks will be happy to assist you in cloud setup.
