ABSTRACT:
The claimed subject matter is directed to a file system watcher in the presence of different file systems to allow synchronization of replicated files distributed among different file systems without compromising the features of each file system. To synchronize the distributed replications, a platform independent synchronization manager creates a file system watcher for each file system associated with a replication of the file. The file system watcher monitors each object for events affecting the object or the object's constituent files, such as creation, deletion, change and rename. Notifications are sent to the synchronization manager, which consolidates the modifications and updates a locally stored replication, if necessary. The synchronization manager then sends a notification of an update to all other synchronization managers for all replications of the distributed file or folder. Synchronization is complete when the nonconforming synchronization managers acquire a replication of the locally stored replication and update their respective objects to conform therewith.
