I finally decided to upgrade to 3TB and use Dropbox for online backups. I am running Windows 10 Pro and have Dropbox installed on the OS drive C: (250gb ssd). Since my OS drive space is limited, I have internal drives for Apps and my data. I am trying to set up a backup of my "Desktop" and "Data" locations, but I seem to be going around in circles. It keeps telling me that "Dropbox and folder are on different drives" when I try to select "Documents" (which is on a different internal drive).
I know I am probably missing something really simple, but I am currently stuck trying to figure it out.

As it states, your Documents folder and Dropbox folder are on different drives, which is not supported. The "backup" function (and I use the term backup very loosely in this case) works by MOVING the Desktop, Documents and Downloads folders into your Dropbox folder. In order to do this, they all must be on the same drive. It doesn't just sync the folders in place and store them in your Dropbox account online. The folders are actually moved and a symlink/junction is left in their place, pointing to the new folder location.
Also, the Desktop, Documents and Downloads folders are the only folders that you can select for this process, and Dropbox will only sync the files and folders that are located within the Dropbox folder. If you have other folders that you want to sync to your account, you'll need to move them into your Dropbox folder.
