How to automate FreeNAS configuration database backup?

[muwakasugi]

I'm using FreeNAS 8.3.0 p1, I have downloaded a FreeNAS configuration file via Web GUI, but how do you automate it?

I have tried cron and searched for "*.db" in the system, but still not sure what file I should backup.

Thanks.

You can automate it however you want. I made a tutorial a few months ago that provides steps to automatically backup your config file nightly. I don't have the link handy, but try doing a quick search.

This works for us.

Code:

#! /bin/sh -

# dumpconfig
#
# Create a volume named "config".  Use high compression and dedupe.
# Create a user named "configmgt" with a home of the volume and
# membership in "operator" group.  Place this shell script in the
# volume.  Set a cron job to run this frequently.  It will make a
# daily archive of the file for two months, then weekly after that.
# It is safe to run it multiple times a day, which has the effect
# of updating the day's configuration file with the most recent
# changes.
#
# This should be combined with rsync or replication to move the
# configuration somewhere so that a copy exists off of the machine
# in question.

set -e

fmt="`hostname`-`sed 's: .*::;s:FreeNAS-:freenas:;s:\.::g;s:-RELEASE:r:' /etc/version`"

# Hourly, daily filenames
hfn="${fmt}-`date +%Y%m%d.%H`.db"
dfn="${fmt}-`date +%Y%m%d`.db"

# Back it up
if [ -f /data/freenas-v1.db ]; then
        cp /data/freenas-v1.db "${HOME}/${hfn}"
        chmod 600 "${HOME}/${hfn}"
        rm -f "${HOME}/${dfn}"
        ln "${HOME}/${hfn}" "${HOME}/${dfn}"
fi

# Yesterday's hourly filenames, wipe them out
ofn="${fmt}-`date -j -v -1d +%Y%m%d.%H`.db"
if [ -f "${HOME}/${ofn}" ]; then
        rm "${HOME}/${ofn}"
fi

# Old daily filenames, wipe most of them
ofn="${fmt}-`date -j -v -2m +%Y%m%d`.db"
if [ -f "${HOME}/${ofn}" ]; then
        if [ `date +%w` -gt 0 ]; then
                rm "${HOME}/${ofn}"
        fi
fi

exit 0

As usual the code itself is trite. A more complex script that included cmp'ing versions was considered but deemed to be unnecessarily complicated, you don't necessarily want every revision in the config to be archived (but if you do this isn't the script for you). Space is cheap on a NAS especially if you can use dedupe.

Thanks, your script works perfect for me as well. Comparing the downloaded file to /data/freenas-v1.db with md5 hash, no difference between them, yay that's what I need!
Now I'll also try to dig the forum to find noobsauce80 thread :)
