Filesystem synchronization utility
SSYNC is a minimalistic filesystem synchronization utility. Its primary goals are reliability, correctness, and speed in syncing extremely large filesystems over fast, local network connections. SSYNC does not implement encryption, compression, differencing algorithms, or remote synchronization over a pipe such as rsh / ssh since those features are already well covered by other utilities such as rsync. It works well on large filesystems and can handle filesystem objects with unusual and non-ASCII characters in their names while correctly preserving all symbolic and hard links and all mode bits. It can be run at increased or decreased niceness and can provide several levels of logging output. Several options allow complete control of synchronization behaviors such as selectively disabling updating of data, ownership, and modes, as well as updating only newer objects or just performing 'test runs'.
