Disaster recovery – By failing to prepare, you are preparing to fail
By Anthony Poh, Solutions architect at MTI Technology - 12 February 2016
Disaster recovery (DR) can be likened to buying an insurance policy – it may cost you a fair sum upfront, and you may never need to use it. Should the worst occur, though, you will be glad you invested in it.
DR solutions have the potential to be of critical importance in disaster scenarios. However, despite the obvious benefits, the Disaster Recovery Preparedness Council reported almost 75 per cent of global companies are failing in terms of disaster readiness.
Given that companies lose on average, $84,000 for every hour of downtime – why are so many companies still failing to prepare?
Advantages of cloud-based disaster recovery
When recovering from disaster situations, some end-users assume that backups or cloud storage are more than adequate protection. The problem with these methods are that end-users never realise how complex and time consuming it can be to recover business-critical services once a problem arises.
In a world where data is growing at an unprecedented rate, there are clear benefits for enterprises moving to cloud-based DR solutions:
- Cost savings - Disaster Recovery-as-a-Service (DRaaS) enables the protection of applications and data in the cloud. This means that companies do not have to spend on hardware, secondary sites, electricity, or even hiring and training new specialists.
- Flexibility - Cloud solutions tend to operate as a flexible, subscription-based model whereby you can pay for what you need, when you need it, with the ability to scale when required. Compare this with traditional DR solutions that would involve buying a fixed amount of expensive hardware resources, and watching it depreciate in value over time.
- Accurate recovery cycle - Recovery Point Objective (RPO) is the length of time in which a business process must be restored after a disaster (or disruption) in order to return to normal operations for a company. As DRaaS protection is typically per virtual machine (or a group of virtual machines), this provides you with greater granular control over replication frequency and recovery.
As businesses are always looking for ways to save on costs without compromising services, moving an auxiliary system like disaster recovery to the cloud is a great solution. It can free up resources for greater operational investment geared for growth.
