Python script to backup FreeNAS configuration file Created by Eric Bright Copyright (C) 2013 Expanded by adding mail, and the use of zpool location of the backup, by Dennis Juhler Aagaard (C) 2014

This script will copy the FreeNAS configuration file (/data/freenas-v1.db) to the location /mnt/zpool/.system/cores. The script copies the configuration only when a change has been made to the FreeNAS Configuration file and mail it to a email account of your choosing. Previous backups will be archived when a new backup is created.

Arguments to the script has been made to make it flexible to which mail server should be used and also introduced a System name independent of hostname og the system in case you have multiple FreeNAS systems you need to have backups from.

Usage: BackupConf.py [options]

Options:

-h, --help show this help message and exit

-n NAME, --name=NAME Name of the system

-m MAILSERVER, --mailserver=MAILSERVER Hostname of mailserver with port; hostname.org:25

-u USER, --user=USER Username for the mail account

-p PASSWD, --passwd=PASSWD Password for your mail account. Beaware that this is in cleartext

-t EMAILTO, --emailto=EMAILTO Mail you want to send the file to

-f EMAILFROM, --emailfrom=EMAILFROM Naming of the email adress sent from. Mostly the same as your mailaccount

Copy BackupConf.py to /usr/local/sbin/ by first mounting the system as writeable with mount -uw /
Change permissions to add execute to backup.py (ex. chmod +x /tmp/backup.py)
Change the system back to read-only with mount -ur /

Log into the FreeNAS Web Interface
Expand System, expand Cron Jobs
Select Add Cron Job

User = root

Command = BackupConf.py -n [name] -m [mailserver hostname] -u [mail account user] -p [password] -t [emailto] -f [emailfrom]

Set it to run each hour to catch your FreeNAS changes. If there has not been any changes, nothing will happen.
