Nearly 70% of firms have experienced a storage system failure and nearly a third of these have lost critical business data, according to the latest research from Computer Weekly and EMC.
Anders Lofgren, senior industry analyst at Forrester Research, said building sufficient redundancy into storage systems is all-important if companies want to avoid storage failures.
"Firms have to have some measure of protection. Traditionally, they have done that through redundancy, so you would have dual controllers, power and cooling controls."
The proliferation of data generated by businesses has fuelled demand for storage systems, ranging from network-attached storage to storage area networks.
The survey showed that the need for back-up and disaster recovery capabilities has overtaken the explosion in e-mail data as the biggest driver behind storage demand. Other factors driving investment in storage are the growth in databases and new applications.
