Step 1
Go to Google Drive and sign in with your school account. UPDATE: Use Google Chrome to ensure everything transfers correctly.
Step 2
Create a new folder. To do this click on the red NEW button and then click Folder.
Step 3
A window will pop up asking you to name the folder. Give it any name you want. Something like 2014-2015 School year might be good.
Step 4
Double Click on the new folder that you just created. This will open it up.
Step 5
Next you'll want to open up finder to the folder you want to backup. Many of you will be backing up your documents folder so that is the one you want to open, but some might have things stored elsewhere.
It is suggested that you resize the windows so that they both fit on the screen without overlapping.
Step 6
To copy your documents into Google Drive, you will have to select them all and drag them into the Google Drive window. Note: You aren't removing them from your computer, just creating a copy in Google.
While the finder window is selected, you can press "command" and "A" at the same time and this will select all of the folder and documents in that window. You can also drag the folders and files one by one.
It may take a few minutes depending on how many files you have, but after that you are all done!
