<p>Disclosed is a method that predicts the managed backup occupancy of a backup system. The method determines the current managed backup occupancy of the backup system, the expected occupancies of backups taken by the backup system per predetermined time period, the expected growth rate of a protected data volume of the backup system per time period, and are the data volumes of existing backups that are expected to expire within the next few time periods. The method then calculates a predicted managed backup occupancy after n time periods based on the above determined values. The above values may be the average of the real measured values over the previous time period, which may be a year. The predicted backup data volumes may be used in a cost comparison engine to work out the cost of backing up the predicted data on the existing system or on an alternative system.</p> |
