Five Advantages of Using Cloud Storage for Disaster Recovery

We all know what cloud means. I am talking about an internet cloud computing.
Cloud computing is location independent computing, whereby shared servers provide resources, software, and data to computers and other devices on demand, as with the electricity grid. Or more simply, remote computing. Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture and utility computing. Details are abstracted from consumers, who no longer have need for expertise in, or control over, the technology infrastructure “in the cloud” that supports them.
In October of 2010, the Aberdeen Group, an industry analyst firm, surveyed over 100 organizations with formal DR programs to learn whether they used public cloud storage for DR and if so, what benefits they saw.
Five Compelling Facts from Aberdeen’s Research
Best-in-Class companies that used public cloud storage recovered from downtime almost four times faster, on average than organizations with no storage in the cloud.
Best-in-Class companies using cloud storage met 100% of their recovery time objectives (RTO) while non-adopters of cloud storage reported that on average, their longest downtime event within the last 12 months exceeded their RTO objective.
Even though the Best-in-Class category only represents the top 20% of all survey respondents, almost half (46%) of cloud-users were ranked among these top performers.
Cloud-based disaster recovery times are similar to recovery times for organizations using disk-based devices.
Users of cloud storage reported on average a 9% reduction in the number of DR events over the last 12 months.
