Google has recently discontinued their standard Google Drive desktop app and replaced it with two new applications: Drive File Stream and Backup and Sync. This article will help to clear up any misunderstandings about the change. Google Drive on the web that you are familiar with is not going anywhere and it still looks and works the same.
Drive File Stream
This is the IMT recommended application that makes your entire Google Drive available on your Mac or PC while using no hard drive space. As long as you are connected to the internet you’ll be able to open and edit your Google Drive files right from your desktop. You are essentially streaming files, just like you would stream video on YouTube or Netflix.
You can also choose to keep certain files or folders offline for editing while you are not connected to the internet. The next time you connect, those changes will be synced to Google Drive on the web, and your work will be saved there.
Drive File Stream is the only application that can give you access to Google Team Drives on your local computer.
Backup and Sync
This is the consumer oriented successor to the original Google Drive app, and still provides the same syncing functionality as its predecessor, but with an additional data backup feature, you can choose to backup any folder on your computer such as Desktop, Documents, and Photos. You can also backup data on attached devices such as drives, or SD cards. Since your APU Google Drive offers you unlimited storage, this is a great way to make sure you always have an emergency backup of your files for work and school. Google has some great documentation if you need additional help on setting up specific settings.
Each computer that you backup with Backup and Sync has it’s own named folder in Google Drive on the web, found in the Computers section, which is separate from the My Drive section where all your Google Drive files are normally stored.
Using Both Drive File Stream and Backup and Sync
You can use both Drive File Stream and Backup and Sync together on the same computer. You’ll want to turn off the Google Drive feature in Backup and Sync so your computer doesn't sync those files twice because File Stream is already syncing those files for you.
