US 2010/0306174 A1 · METHOD AND APPARATUS FOR BLOCK BASED VOLUME BACKUP

Abstract

Embodiments of the invention provide methods and apparatuses for block based storage subsystem to have backup ability to a file based storage service such as HTTP or cloud storage service. In one embodiment, a storage system is coupled via a network to a storage service which has one or more file servers. The storage system comprises a processor; a memory; a volume-based snapshot control module configured to create a snapshot volume of data at a certain time, the snapshot volume being a block-based volume which is divided into a plurality of portions; and a copy control module configured to read each portion of the snapshot volume and send said each portion as file data to the storage service via the network, and to generate mapping information between an address of said each portion in the storage system and a file identifier of the file data of said each portion in the storage service.
