rsync is a software application and network protocol for Unix, Linux and Windows systems which synchronizes files and directories from one location to another while minimizing data transfer using delta encoding when appropriate. An important feature of rsync not found in most similar programs/protocols is that the mirroring takes place with only one transmission in each direction. rsync can copy or display directory contents and copy files, optionally using compression and recursion.

rsyn and FTP
rsync need SSH access to work, but you can also use it with an FTP server if you mount it locally with curlftpfs:
- Install curlftpfs and rsync
$ sudo apt-get install curlftpfs rsync
- Create mountpoint
$ mkdir /path/to/mount
- Mount remote directory
$ curlftpfs ftp.example.com /path/to/mount
- Create local directory
$ mkdir /local/path
- Rsync mounted directory to local directory
$ rsync -r -t -v --progress --bwlimit=500 /path/to/mount/ /local/path/
