Abstract
A system for progressive just-in-time restoration of data from backup media. Backup data may be divided into a plurality of chunks and stored on any kind of media such as a direct attached storage (DAS) disk, object storage, USB drive, network share or tape. An index map is maintained that indicates the location of each of the plurality of chunks in cloud storage, the index map representing contiguous blocks of backup data of a volume. The backup data may be compressed, encrypted, or de-duplicated. The backup data may be located on different media, object stores, or network shares, or at differing geographic locations. To perform a recovery, a virtual LUN or virtual volume is mounted and provided to the operating system and applications of the restored computer. Chunks may be progressively copied from cloud storage to a data cache and restored in response to requests for blocks.
