There are a lot of good Online backup Web sites out there today. Since Gmail first hit the scene though, people have been trying to use it to have a little extra storage space on their computers. Now there is yet another tool that helps you manage this process and your files in the Firefox extension, Gspace.
This extension allows you to use your Gmail Space (2.8 GB and growing) for file storage. It acts as an online drive, so you can upload files from your hard drive and access them from every Internet capable system. The interface will make your Gmail account look like a FTP host.
Out of all the “lets use Gmail for backup” tools out there, this one is the best that I have seen thus far.
