A disaster can be anything that can put an organisation’s operations at risk be it, cyber-attack or equipment failure. Every organisation faces the risk of experiencing a disaster of any form at any time. This is where cloud backup and disaster recovery services come into play and minimise the risk to the business. The goal of Disaster Recovery is to provide continuity of operations in case of such an event. Disaster Recovery is a broad term, while not limited to just physical disasters; it can mean data protection from different types of vulnerabilities that your business can be exposed to. Therefore, Business Disaster Recovery Services should be an essential part of the business plan as it is highly possible that your data is at risk from equipment failure, corruption, theft or cyber-attacks.
Disaster recovery services provides constant replication of data in real time across different physical locations. The process of disaster recovery can include planning and testing which involves different physical sites for restoration.
When implementing a DR solution, the most important components of cloud backup and cloud disaster recovery services are Recovery Point Objective and Recovery Time Objective.
The point in time relative to the failure to which you need preservation of data. It is actually the age of the files or data in backup storage required to resume normal operations if a computer or other system or even a network failure occurs. It also determines the frequency of backup required for your organization. For example, if the RPO is one hour, backups must be made at least once an hour.
The amount of time an organization can ideally have ‘downtime’, which becomes a concern for most businesses, as downtime could result in loss of business and can impact customer satisfaction. The goal here is to calculate how quickly you need to recover your data, which can then dictate the type or provisions you need to implement the same and the overall budget you should assign to business continuity.
Thus, calculating the Recovery Point Objective and Recovery Time Objective are the building blocks of your disaster recovery plan. There are three approaches to Disaster recovery –
Also known as DRaaS (Orchestrated Disaster Recovery as a Service), recovers in a specific order by resorting data automatically. It also helps applications to be restored and process as one of the essential features of Business Disaster Recovery Service.
This approach replicates your workload to Azure in real time, and migration happens quickly, with just few clicks. Access to information is never lost during a state of disaster. User bandwidth stays unaffected as you can run heavy load programs and analytics.
In this approach, the site recovery continuously keeps a remote check on your protected instances. The data stays encrypted even when the data is replicated on the secondary site.
