I've got the android app termux installed on my phone, you get a linux
command line. You can install sshd and then you can sftp/scp to your
heart's content (or at least as much as android allows :-)

With sshd running on the phone, you can use sshfs from another linux
machine to mount the accessible parts of the android filesystem.
The use of rsync for backups is also a possiblility.
