Weekend Gadget Guidance: Sync files between computers over the Web, free
Freeware application and Web service Dropbox instantly backs up and syncs your files over the Internet and to any Windows or Mac computer.Once you install the application, it will create a Dropbox folder on your hard drive.
Once you install the application, it will create a Dropbox folder on your hard drive. Any file you put inside that folder will sync automatically and be monitored for changes. Each time a change is made (and saved), it backs up and syncs the file again. Dropbox also does revision history, so if you accidentally save a file and wanted to revert to an old version, Dropbox can recover any previous version.
Any file synced with Dropbox is available on any computer you sync it to or through the Dropbox web interface.
Dropbox is currently in closed beta, and I'm currently working to get Toybox readers some exclusive invites. In the meantime, Lifehacker has 500 invites for for people to try it out (beta code is "lifehacker"). I've got 200 exclusive invites for ToyBox readers: go to http://www.getdropbox.com/beta/zdnet and use code "zdnet" to access. If the invites run out, all new users get 10 invites of their own, so keep your eyes peeled -- then post your invites here in TalkBack. (Thanks, Jon!)
During the beta, Dropbox is limited to 2GB of storage space and syncing. Afterward, the software and service will remain free of charge, but if more than 2GB of space will require a premium account. Dropbox is currently Windows- and Mac-ready with a Linux client on the way.
