Allow downloading database backups

I'm running on a NVidia Shield. The only easy way to copy items off of it is via SMB. Problem is, the credentials are dynamically generated and only viewable with a TV connected. I run the SHIELD headless. Therefore, I can't get the credentials to copy a database backup. Would hate to lose all my data if the USB HDD I have connected were to fail. Hoping you can implement a simple "download most recent backup" option on the DVR web UI.

EDIT: For extra credit, do this but also offer automatic cloud backups as part of the Channels Plus subscription! The database can't be that big, right?
