Rsync backup van alle user data met monitoring

vanaf syn3 versie 4.5 is deze functionaliteit onderdeel van de reguliere backup instellingen in de control center

• Fix een ssh key naar de server die je wilt backuppen:

  [Syn-3] root@backup.asdf.nl /etc/cron.daily# ssh-keygen
  Generating public/private rsa key pair.
  Enter file in which to save the key (/root/.ssh/id_rsa):
  Enter passphrase (empty for no passphrase):
  Enter same passphrase again:
  Your identification has been saved in /root/.ssh/id_rsa.
  Your public key has been saved in /root/.ssh/id_rsa.pub.
  The key fingerprint is:
  88:15:b5:75:0e:ed:93:0a:1f:8f:36:78:55:d6:29:db root@backup
  [Syn-3] root@backup.asdf.nl /etc/cron.daily# cat ~/.ssh/id_rsa.pub | ssh root@192.168.1.160 "cat >> ~/.ssh/authorized_keys"
  root@192.168.1.160's password:
  [Syn-3] root@backup.asdf.nl /etc/cron.daily# ssh root@192.168.1.160
  Last login: Tue Mar  3 12:44:06 2009 from 192.168.5.11
  Linux.
  ... (inloggen zonder password nu mogelijk)
  

• Maak een user 'backup' op de backup server aan via de SCC
• Plaats dit script in /etc/cron.daily en pas het aan:

  NAME=emmen
  IP=192.168.1.160
  if rsync -avx $IP:/home /home/users/backup; then
   /sbin/syn3-state --force rsync-$NAME OK "mirror backup `date` gelukt"
  else
   /sbin/syn3-state --force rsync-$NAME ALERT "mirror backup `date` mislukt!"
  fi
  

Niet vergeten de x-bit te zetten!

• Test het script:

  [Syn-3] root@backup.asdf.nl /etc/cron.daily# ./emmenbackup.sh
  receiving file list ... done
  home/shares/...
