Google Drive is a relatively simple, but convenient way to backup and share files between computers. Have a project you are working on at work? Throw it in Drive and finish it when you get home. It is nothing new, but it is effective, and many people use it.
However, Google wants to offer more with Drive. The folks in Mountain View are looking to turn Drive from a virtual thumb drive into a more functional backup utility. To that end, they’re developing a new app called Backup and Sync.
