"The storage software market continues to exhibit steady growth, particularly in the replication and backup and archive segments, driven by customer requirements of trying to protect and secure information in an increasingly complex IT environment," said Rhoda Phillips, research manager for IDC Storage Software. "This demand is in response to the growth of information and the impact of the requirements to have more information online with greater protection throughout the entire business cycle."
