Jungle Disk lets you store files and automatically backup data easily and securely. Jungle Disk has a great automatic backup system, and can easily be used for basic data backup, but Jungle Disk also gives you a complete network drive that you can use from multiple machines - like an unlimited size USB drive that you can connect to from anywhere. The exclusive caching features in Jungle Disk make it so that using your network drive is as fast as a local drive, and you don't need to constantly transfer data from the server.
