I'm going to click on the batch thingy with the checkmark and backup all apps and data...in prep for HDR?...
I think you mean "FDR" ... Factory Data Reset ... but yes.
HOWEVER, be careful when you do the FDR ... if you select "wipe internal storage" it will delete your TB backup folder and you will have to start all over again and reinstall all your apps. But once you have paid for an app you won't have to pay for it again, it's tied to your email address in the phone.
