Bert,

Air-Gapped is the highly intuitive and technical term meaning there is absolutely positively without a doubt no way for "device A" to connect to "device B". Let's say Device A is your computer and Device B is your USB drive. Disconnect your USB drive, take it into another room and place it in a lock box labeled "DO NOT USE WITHOUT SIGNED AUTHORIZATION FROM BERT." There. It's air-gapped. The fact that you backup to external USB drives (have to have more than one) and AT LEAST ONE OF THEM IS DISCONNECTED AT ALL TIMES means you're pretty darn close to having an air-gapped backup. Real close.

Windows Mounts are when Windows mounts a device and assigns it a drive letter or other means to communicating with it. When you insert a USB drive and in File Explorer is shows up as Drive G, that is a mount point.

SFTP means Secure File Transfer Protocol. FTP by itself is insecure. SFTP is the secure version using Secure Shell (SSH) or SSL. Having a backup software send the backup over via SFTP would count as air-gapped (for the most part, GE would not let this fly) as credentials must be passed over for the connection to the remote site.
