Disaster Recovery as a Service (DRaaS) is the replication and hosting of physical or virtual servers by a third-party to provide failover in the event of a man-made or natural catastrophe.
DRaaS can be especially useful for small to mid-size businesses that lack the necessary expertise to provision, configure and test an effective disaster recovery plan (DRP). Using DRaaS also means the organization doesn't have to invest in -- and maintain -- their own off-site DR environment. An additional benefit is that DRaaS contracts can be flexible as the business' needs change. The downside, of course, is that the business must trust that the DRaaS service provider can implement the plan in the event of a disaster and meet the defined recovery time and recovery point objectives.
Companies offer their professional service to end users such as small to medium size businesses. These companies are responsible to backup your data on a daily basis. Furthermore, in case of a system crash or disaster the company will restore your data. This saves smaller companies money and eliminates a lot of end user issues.
The major problem in a data recovery disaster plan is human error. Furthermore, small business owners have no idea how to write and implement a disaster recovery plan for their business.
Disaster Recovery-as-a-Service (DRaaS) as part of a comprehensive availability strategy, embracing investments made in your datacenter and extending them through the hybrid cloud.
Disaster recovery prepares for the recovery and continuation of technology infrastructure after a natural or man-made disaster. For businesses, a disaster means abrupt disruption of all or part of business operations, which may directly result in loss of revenue.
There are disaster recovery sites and servers provided by data centers that help keep both your data and system replicated off-site, which enables you to continuously access your systems and data in case of disasters.
Disaster recovery (DR) system in the cloud servers aims at protecting the critical data and provide continuity in business. It is highly cost effective solution as it works on “pay per use” model and also eliminates the need for large upfront capital investment to build a secondary DR site.
Disaster recovery is security planning that deals with protecting an organization from the effects of negative events or disasters(natural or manmade).
When related to IT, organisations chalk out an effective Disaster Recovery Plan (DRP) beforehand, to roll-back when the disaster strikes.
The DRP replicates the entire computing environment and makes it available.
