About
Rsync is a tool for creating backups in Linux systems. It supports backing up local folders, SSH tunneling, delta-only synchronization, and so on.

Grsync adds the ability to use such purposes with a graphical user interface, without rsync's need to learn a complex set of command-line arguments. In some cases, it is easier to backup files with grsync than with rsync. Since version 1.3.0, Grsync has GTK-3 compatibility.
