Cloud computing and business continuity
Where and when should you consider this approach?
IT plays a fundamental role in most organisations’ day-to-day activities, underpinning how they achieve their objectives and go about their business. If and when those IT services are not available, the organisation can come to a grinding halt. The discipline of business continuity provides enterprises with the planning and tools to protect themselves against these problems, from large disaster events such as a fire or flood, through to smaller IT problems such as lost data or a broken server. IT itself is also in transition: the ‘new model’ of cloud computing is being adopted with the vision of making services to the business more flexible and cost effective. Around business continuity, the cloud has the potential to make backup and recovery available to a wider section of the market, providing advanced level functionality that is aimed at the enterprise while still keeping costs low enough for all companies to benefit.
The main question around backup, recovery and the cloud is whether this approach can fulfill its early promise, and how it can work for them.

Understanding recovery To answer this question, organisations have to look at the basics of disaster recovery (DR) and continuity planning. This means understanding three things: £ How up to date the organisation’s data has to be, and how much data it can stand to lose. This is the Recovery Point Objective (RPO)
£ How quickly the organisation wants to be back up and running after any disaster. This is the Recovery Time Objective (RTO)
£ How much control the organisation has to retain over its data. For example, can the company move information over to a third party, or does this have to remain internal? Can data leave the country or region boundaries?
Depending on the market that they work in, the regulations surrounding their industry, and the budget they have available, each business will have to define different RTO and RPO goals. For European organisations, they will have different challenges
