ON-DEMAND RESTORE OF A SNAPSHOT TO AN ON-DEMAND VOLUME ACCESSIBLE TO CLIENTS

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.
