    摘要: In one example, a method of restoring data backed up in a content addressed storage system may include retrieving a recipe and appended storage addresses from a first storage node of content addressed storage, where the recipe may include instructions for generating a data structure from two or more data pieces, and the two or more data pieces may be resident in locations identified by the appended storage addresses. The example method may further include populating a cache with the appended storage addresses for the two or more data pieces. As well the method may further include retrieving, and populating the cache with, the two or more data pieces without looking up a storage address for any of the two or more data pieces in an index, and restoring the data structure using the retrieved two or more data pieces in the cache.
