Abstract
A zymbolic history management system (ZHMS) allows a user to create annotated symbolic links (zymlinks) to files in a shared file system. A single link is created to each file of the shared file system which a user wishes to access. A zymlink to the shared file system may be updated via a zupdate command. Rather than selectively updateing individual files, a user simply zupdate's whole trees of files. When it comes time to edit files, a user makes use of standard history managed file system commands to obtain a writable copy of a file. Use of one of these commands destroys a zymlink corresponding to the file, and substitutes a privately owned copy of the file on a user's disk. When the edited file is checked back into the history managed file system, a read-only copy of the file remains on a user's disk. When a user updates his or her file system, the read-only file copy may be replaced with a new zymlink. A user will normally view current versions of shared files. Rather than viewing current versions of shared files, a user may wish to maintain a static view of file versions by issuing a zreset command. The system provides a user with more free disk space than in conventional history managed systems.
