You can back up to a remote system without root login, but you'll lose
all of your files owners and groups. Non-root users can't change file
ownership, and can't change group ownership to groups of which they are
not a member. Unless you use root or sudo (it's possible), you'll lose
that information, which means you won't be able to do a direct system
restore from that backup. You'll only be able to restore the contents
of select files, mostly configuration and data files.
