Strategies Backup and Restore for data deduplication

摘要

A process backup data stream, comprising: identifying for backup a plurality of streamlined data stored in a warehouse of fragments (118, 300, 1334), including the store fragments each data stream optimized as a plurality of fragments and metadata corresponding optimized flow, the plurality of fragments at least a piece of data (208; 322), referencing the metadata flow optimized for the at least one piece of data, and including the store fragments all pieces of data including a desduplicada form; and storing at least a portion of the store fragments into a storage backup (1304) to perform a backup of the plurality of streamlined data identified for backup, wherein said storing comprises: selecting (1802 ) technique backup of a plurality of techniques backup based on heuristics, in which a trade-off in the art backup is based on a differential between an optimized size and logical file size the plurality of data streams optimized identified for backup; and performing (1804) the backup technique selected to perform a backup of the plurality of streams optimized data storage backup.
