  ssh springm@hermes

  sudo su
  echo "restic --no-lock -p /root/resticpw -r /backupdisk/restic-repo mount /resticrestore" | at now
  cd /resticrestore/hosts/kudell/latest
  tar cvjf /tmp/kudellroot.tg2 root
  tar cvjf /tmp/kudelletc.tg2 etc
  tar cvjf /tmp/kudellspringmssh.tg2 home/springm/.ssh

Auf kudell:
  scp springm@hermes:/tmp/kudell*2 /tmp
  cd /tmp
  for f in *2; do tar xjf $f; done
  cd ~springm
  mv ~springm/.ssh ~springm/.ssh.old
