As IT systems have become increasingly critical to the smooth operation of a company, the importance of ensuring the continued operation of those systems, or the rapid recovery of the systems, has become vital.

It is recommended that companies spend between 10% and 25% of their IT budget on IT disaster recovery planning, with the aim of reducing the impact of a loss of critical IT infrastructure and data. Of companies that had a major loss of business data, 23% never reopen, 52% close within two years, and only 6% will survive long-term (DTI). As a result, preparation for the continuation or recovery of systems needs to be taken very seriously. This involves a significant investment of time and money with the aim of ensuring minimal losses in the event of a disruptive event.
