Create Synchronicity is a backup application that synchronizes files and folders and includes a scheduler.
Create Synchronicity works with one or more user profiles. This allows you to specify what you want to back up as well as when or where. For example, you could create a backup of your documents in one profile and your photos in another allowing you to decide when, and where, they are backed up. You can also manually backup at any time, change settings and even preview what will be backed up. Log files are always available as well.
But, wait, there's more. You can back up on a network, use compression to save space, batch sync, multiple language support, an optional command-line interface, and as much as we hate to repeat ourselves, and more.
Create Synchronicity is a full-blown, professional quality backup app that's portable, Open source and only 210KB.
