How do I set up backup to use internal drive?

How do I set up internal drive for backup. I go to backup section and don’t see internal drive listed.

What are we talking about here exactly? You can’t backup to the same drive, you can’t backup to an internal drive… if you have a nucleus or Rock, you can either use an external usb drive or smb share to backup to. Note that database and music are two different things with regards backups.

Thank you.

That’s not a good idea even if you could. Use a USB drive.
