Abstract
Systems and methods are described for backing up files and directories using a common backup format. The files and directories may be represented by objects within a data stream constructed using the common backup format. The data streams may be traversed and updated using a size tree such that modifications are made to individual objects within the data streams without complete traversal. This process results in efficient management of storage systems as read and write operations are not dependent on exhaustive traversal of data streams.
