Description: A generic file repository synchronization tool syrep is a generic file repository synchronization tool. It may be used to synchronize large file hierarchies bidirectionally by exchanging patch files. Syrep is truely peer-to-peer, no central servers are involved. Synchronizations between more than two repositories are supported. The patch files may be transferred via offline media, e.g. removable hard disks or compact discs. Files are tracked by their message digests, currently MD5. The following file operations are tracked in the snapshot files: creation, deletion, modification, creation of new hard or symbolic links, renaming. (The latter is nothing more than a new hard link and removal of the old file). syrep doesn't distuinguish between soft and hard links. In fact even copies of files are treated as the same. Currently, syrep doesn't synchronize file attributes like access modes or modification times.
