Abstract: Systems and methods for preserving storage efficiency during restoration of data from the cloud are provided. In one embodiment, a CBMAP is maintained that maps cloud block numbers (CBNs) to respective corresponding block numbers of a volume of a data storage system in which previously restored data has been stored by a previously restored file. By making use of the CBMAP during the restoration process, storage of duplicate file data blocks on the volume may be avoided by sharing with a current file being restored a reference to the corresponding file data block previously stored on the volume and associated with the previously restored file. In addition to preserving storage efficiency, use of the CBMAP facilitates avoidance of repeated GET operations for data associated with CBNs previously retrieved from the cloud and stored to the volume, thereby reducing data access costs as well as latency of the restore operation.

Abstract: Techniques are provided for caching data during an on-demand restore using a cloud block map. A client may be provided with access to an on-demand volume during a restore process that copies backup data from a snapshot within a remote object store to the on-demand volume stored within local storage. In response to receiving a request from the client for a block of the backup data not yet restored from the snapshot to the on-demand volume, the block may be retrieved from the snapshot in the remote object store. The block may be cached within a cloud block map stored within the local storage as a cached block. The client may be provided with access to the cached block.
