Abstract
A server file replication technique is implemented with three local copies of a replicated file. First, a shadow file is a copy of the last known good version of the file on the server. Second, a local copy is the user's working copy. Whatever changes the user has made to the file are stored in the local copy. Third, a rollback file is a copy made of the local copy if the local copy changes (for example, when conflicts are resolved or the server version is copied to the local copy.) Different states exist, based on whether these copies contain differences from each other and from the server version, and based on the user's use of the document. These states guide what is done to maintain the local copies and whether conflict resolution is required.
