QSynergy is a comprehensive and easy-to-use graphical front end for Synergy. Synergy lets a user control more than one computer with a single mouse and keyboard (and has lots and lots of extra features on top of that). Since Synergy only has a GUI for MS Windows, QSynergy was written to step in and fill this gap for users on Mac and Unix platforms.
SynchroDir is a backup and synchronization utility. Each backup is the subject of a recordable "backup project". This feature allows you to save projects corresponding to different computers, servers, external hard drives, USB keys, etc. You can also backup data of computer Y to computer Z from a controlling computer X. Each backup project includes an unlimited number of "jobs". At the end of the backup process, a log file is available. Each job has a source and a destination, each corresponding to a volume or a directory. The volume or directory must be "mounted", either locally or over the network.
