Switchback

This is the Japanese version of the SwitchBack package. 5 Cows (highest rating) at Tucows! SwitchBack is a file synchronization and backup utility. SwitchBack makes it easy and safe to synchronize two disks, so that both contain your most recently updated documents. Simply choose two folders to compare, and SwitchBack does the rest, quickly and painlessly. The two folders can reside on the same or different disks, or on two computers connected by a network, or even over the Internet. You can ask SwitchBack to tell you in detail what it is doing, or let it go to work, only advising you when there's a problem. It has been designed principally for those people with two computers (especially desktop and laptop) who need to ensure that they have the most recent version of their documents available to them.
