# nainstujeme rsync, wget a sudo
apt-get install rsync wget sudo

# přidáme uživatele backuppc bez hesla
adduser -q --disabled-password --gecos "" backuppc

# přidáme mu práva spouštět rsync jako root
echo "backuppc  ALL=NOPASSWD: /usr/bin/rsync" >> /etc/sudoers

# staneme se jím :-)
su backuppc

# a stáhneme si SSH veřejný klíč
