Google Drive Backup

The best practice to secure your Google Drive Docs syncronized and backup is to have the Google Drive App install in one of your computers. 

How to have Google Drive on your computer?

1. Go to Google Drive download
2. Install the application on your computer.
3. On your computer, you'll see a folder called "Google Drive." located in Win10 in the "Quick Access" section (Window Explorer)
4. Now you have access to all the material you previously saved in your Google Drive. You can do:
1. Copy all those files in a safe location as a backup
2. Drag files or folders into that folder. They will upload to Drive and you will see them on drive.google.com. In other words, they will be in the cloud. The program will synchronize whatever you add to the folder as well as remove whatever you remove from it. So use this folder wisely.

Other ways to do more automatic however less out of you control is to use the Google Takeout app. This is a Google service created to allow users to back up any of their Google Service.

Be wise
