A CVS exclude mode for ignoring the same files that CVS would ignore.Exclude and exclude-from options similar to GNU tar.Support for copying links, devices, owners, groups, and permissions.Some of the additional features of rsync are: Any changes in the other preserved attributes (as requested by options) are made on the destination file directly when the quick check indicates that the file's data does not need to be updated. Rsync finds files that need to be transferred using a "quick check" algorithm (by default) that looks for files that have changed in size or in last-modified time. rsync is widely used for backups and mirroring and as an improved copy command for everyday use. It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination. It offers a large number of options that control every aspect of its behavior and permit very flexible specification of the set of files to be copied. It can copy locally, to/from another host over any remote shell, or to/from a remote rsync daemon. Rsync is a fast and extraordinarily versatile file copying tool.
