Abstract
Techniques for representing directory structure in content-addressable storage systems are provided. A directory structure of a file system is represented using a plurality of chunks in a content-addressable storage system. The directory structure includes a set of objects arranged in an object hierarchy. The set of objects includes a particular directory that has, within the object hierarchy, a set of child objects. The plurality of chunks includes a directory object chunk for the particular directory. The plurality of chunks further includes a particular set of child object chunks. The particular set of child object chunks are object chunks for each child object in the set of child objects. The plurality of chunks further includes at least one hash set chunk with hash values for object chunks in the particular set of child object chunks.
