A method for efficient backup and restore using metadata mapping comprises maintaining a first backup aggregation associated with a primary data object of a primary host at a secondary host, wherein the first backup aggregation includes a first backup version of the primary data object stored within a secondary data object at the secondary host. The method further comprises generating a second backup aggregation, wherein the second backup aggregation includes a second backup version of the primary data object and a backup metadata object corresponding to the secondary data object. The backup metadata object includes a pointer to the second backup version. The method may further comprise restoring the secondary data object, wherein said restoring comprises using the pointer to access the second backup version of the primary data object to restore at least a portion of the secondary data object.
