TRACKING AND REPLICATING FILE SYSTEM CHANGES

摘要

Management of file system changes among multiple instances is provided using the system of Fig. 1. Changes to file systems include addition, modification, and removal of files. A modification sentry (102) monitors file system operations taking place on the source file system (108). When a file is modified on the source file system (108), the modification sentry (102) makes a corresponding entry in the repository (104). If a file is added, the file name and file contents are stored in the repository (104). If a file is modified, the file name, modification, and additionally the entire file are stored in the repository (104). If a file is removed, only the name of the file is stored in the repository (104). Logic is also provided for propagating modifications to special type files. To propagate the modifications to target file systems (110), a file system update engine (106) of packages a vector derived from the repository (104) for application to other file systems.
