IT infrastructure is perhaps the most important physical asset of a business. An IT failure could very well result in the closure of the business. This is because, IT infrastructure literally puts all “the eggs into one basket” and enterprises need to watch it 24/7! The alternate is to clone the basket or at least the “eggs” and to keep it where you can retrieve it in case your original basket is struck by a disaster. Storing against disaster is common sense. But, evaluating the solution you adopt makes for business sense.
Cloud strategists will inform you that tech savvy businessmen store their data in the cloud. You will be told that they do not need a gold plated budget to do so! They can create cost effective, fully redundant, active failover disaster recovery (DR) solutions that are accessible from anywhere, anytime for disaster recovery. They will be assisted in the task of separating mission-critical IT assets from non mission-critical information. The cloud based storage provider has designed a storage vault that protects each category of data by aligning value of the data to the cost of protecting it.
Interestingly, a number of new technologies will be shown to supplement the overall data protection strategies of the service provider. Apart from installing reliable, resilient and controlled data centers that are replete with generators, power conditioners, redundant routers and clustered servers, the provider will assure you that they can empower your enterprise with long term archival storage to real time, highly available application failovers to support disaster recovery. Compression, de-duplication, encryption and data categorization strategies will be offered as a part of the package or applied to data stores with recovery time objectives (RTO) and recovery point objectives (RPO) in focus.
Of course, since digital data accumulation has snowballed in the modern enterprise, disaster recovery in the cloud has also become very complex. Remote DR site offers can be for mirrored, hot, warm or cold sites that map to mission-critical, business-critical, online and non-critical offline systems. Mirrored sites are active parallel sites that are essential for application availability in real time or near real time data recovery scenarios. Hot sites reconstitute applications and rapidly resume operations in the event of disaster. Warm data centers host minimum hardware and software to assist the enterprise, re-build applications and resume operations if the primary data center is hit by a catastrophe. Cold sites are basically storage sites with basic infrastructure such as power, telecommunications and sufficient space for equipment and data stores.
Tech savvy businessmen will not be seduced by the complexity of the offers. The solution must fit the problem and address the business needs. A detailed evaluation of complex disaster recovery solutions must always be the way to go!
