I use Total Commander, which, as the name suggests, is a bit like Midnight Commander. A number of plugins can be installed, including SFTP, and, yes, it can be set up to use SSH keys. I've used it for a few years now.
BACKUPS are unsexy — until you discover you should have done one yesterday.
Spare your nerves and do one before you upgrade or install.
