And so as to help someone else, why did my restore take so long: I used an HTC Backup to Dropbox, and when you factory reset, it installs old versions of certain apps, like Dropbox, and when I should try to sign in to Dropbox to access the backup file, it would simply tell me my app was old and needed to be updated. So then I had to go to Google Play, only to not find any Dropbox app (why, because Play store thought I had the lastest version as Google still saw my latest apps uploaded). So I found Uptodown (a store that saves older versions of android and other apps), had to access it on the Internet via the phone (manually download the latest version--oh, and you need to turn on downloading from "Unknown sources" via Settings > Security first.) Then once you make sure the latest Dropbox is on the phone, you can go through your Settings > Backup & Reset > Backup to HTC (or select HTC) then you have other options popup underneath and you need to restore from HTC Backup. It should then ask you to choose either Google or Dropbox and voilà, you choose Dropbox and follow the rest of the instructions (Allow HTC with your account name by pressing & holding that line down, not the green backup image.) But to even get to all of this, you have to make sure NOT to select Google and any Google accounts for anything during the entire reset up process just after the factory install. If not, the options you see later when you access settings after the factory reset is complete will not be the same. Of course this was a pain because I had my backup on Dropbox, I might not have had as many issues had it been on Google Drive.
