Abstract: Data is replicated on a backup node, where the granularity of the replication can be less than a full volume. A data consistency group comprising a subset of data for a volume is defined for a primary node. A set of differences for the data consistency group is sent to a backup node. The backup node creates change logs in response to receiving the set of differences. In response to receiving a request to access a file having data in the data consistency group, the backup node creates a clone of the file. The backup node determines whether an update to a data block of the file exists in the change logs. In response to determining that the update to the data block exists in the change logs, the backup node updates a copy of the data block for the cloned file with data in the change logs.

Abstract: An enterprise may use file level and block level storage for operational access to reap the performance benefits, and use object storage for back-up storage and scale out. Data of objects and objects themselves can be organized to allow for efficient storage management operations, including storage snapshot operations and deduplication operations. A root file container can be represented in object storage with a metadata object (“file container object”) and child file container can be represented in object storage with a metadata object (“file group object”). Each file can be represented in object storage with a metadata object that indicates the data units of the file depending upon the storage technology hosting the file (e.g., a file data block in file level storage). The data units of the file can be represented in object storage as elements of a data object.
