A method and system for predicting the managed backup occupancy of a backup system are disclosed. The method includes determining the variables m0, x1 to xn, r and z1 to zn. Variable m0 is the current managed backup occupancy of the backup system, x1 to xn are the expected occupancies of backups taken by the backup system per predetermined time period T with retention periods of 0-1 time periods T, 1-2 time periods T, 2-3 time periods T and so on up to n time periods T respectively, r is the expected growth rate of a protected data volume of the backup system per time period T, and z1 to zn are the data volumes of existing backups that are expected to expire within each of the first to nth time periods T after the current time respectively. |
