Abstract
A method for managing archived data includes creating a plurality of images of storage devices of computing systems and for, different users, each image being associated with a restore point of a particular storage device; storing the images for the different users in different storage locations, the storage locations being controlled by a single backup server and belonging to storage pools. Multiple locations of one user are stored in different pools on different storage devices. The method also involves moving contents of locations of one user from one pool to another in predefined direction, simultaneously with reorganizing images within the locations. Each image is a backup of one user's data. At least some of one location's content is frozen so that it is never moved from one pool to another. The storage devices of locations of different pools differ from each other by type, such that storage devices in a first pool are hard disk drives, storage devices in the next pool are SAN, or an NAS, and a storage device in the next pool is a network disk drive accessible through a network and a storage device in the next pool is a magnetic tape drive.
