Although the concept -- and some of the products and services -- of cloud-based disaster recovery is still nascent, some companies, especially SMBs, are discovering and starting to leverage cloud services for DR.
Triage is the overarching principle used to derive traditional as well as cloud-based DR plans.
The process of devising a DR plan starts with identifying and prioritizing applications, services and data, and determining for each one the amount of downtime that's acceptable before there's a significant business impact.
Disaster recovery in the cloud is a relatively new concept, and like many technology trends, there's a lot of hype and misinformation out there.
In this Storage magazine article from Jacob Gsoedl, you'll learn about the top cloud disaster recovery concerns, like security and data recovery, and whether or not disaster recovery in the cloud is a good choice for your organization.
"A combination of cost and recovery objectives drive different levels of disaster recovery," said Seth Goodling, virtualization practice manager at Acronis Inc. An increasingly popular option is to put both primary production and disaster recovery instances into the cloud and have both handled by a managed service provider (MSP).
By doing this you're reaping all the benefits of cloud computing, from usage-based cost to eliminating on-premises infrastructure.
Having DR sites in the cloud reduces the need for data center space, IT infrastructure and IT resources, which leads to significant cost reductions, enabling smaller companies to deploy disaster recovery options that were previously only found in larger enterprises.
"Cloud-based DR moves the discussion from data center space and hardware to one about cloud capacity planning," said Lauren Whitehouse, senior analyst at Enterprise Strategy Group (ESG) in Milford, Mass.
With applications identified and prioritized, and RTOs defined, you can then determine the best and most cost-effective methods of achieving the RTOs, which needs to be done by application and service.
