With headcount and budget staying flat, organizations are being asked to do more with fewer resources. One of the key areas of focus is improving application availability, as well as the quality of the backups. Many organizations require 24 X 7 X 365 and can’t afford to be done. Even those that aren’t up all the time, still have limited time in which to manage their backups. And all the while, the business is requiring that we get the most of today’s assets – even in the face of the information explosion we’re facing. But backing up data is not the only business requirement. Data loss and even disasters do occur. So in addition to everything else, IT dept.’s must be able to recovery quickly from any data loss situation. * Symantec Confidential
