Abstract
Systems and methods for backing-up data from a first storage pool to a second storage pool using difference information between time states are disclosed. The system has a data management engine for performing data management functions, including at least a back-up function to create a back-up copy of data. By executing a sequence of snapshot operations to create point-in-time images of application data on a first storage pool, each successive point-in-time image corresponding to a specific, successive time-state of the application data, a series of snapshots is created. The snapshots are then used to create difference information indicating which application data has changed and the content of the changed application data for the corresponding time state. This difference information is then sent to a second storage pool to create a back-up copy of data for the current time-state.
