Preperation

Initialize a borg-repository on the server which should store the backup-repo:

borg init --encrpytion=repokey /path/which/is/configured/in/backup-script

The following line has to go into the corresponding authorized_keys file on the Host which should store the backups:

command="/usr/bin/borg serve --restrict-to-path /path/which/is/configured/in/backup-script",restrict ssh-rsa ....

Actual backups

Adjust backup.sh to your needs and execute it.
