= 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:

 * 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/...
