TrueNAS-12.0-U1 Backup config file daily

[sorinciupitu]

Hello,
I'm new in TrueNAS world and I want to ask you how I can backup my config daily, because I run TrueNAS from usb flash drive and I know the risk. After I search on this forum, I find a code line that I run with Cron Jobs. My name pool where I save the backup file is "work" and folder in that pool is "work". This script it save a file, but I'm not sure if that file is good for restore (like I said my version is TrueNAS-12.0-U1). The line is:

Code:

tar -cvf /mnt/work/work/"$(date +%Y_%m_%d)_$HOST_$(cat /etc/version | cut -d' ' -f1).tar.gz" -C /data freenas-v1.db pwenc_secret

Thank you!

you dont have to backup your config every day, just do a backup after you changed settings. a backup of the boot config on the (in case of an error not running) pool /mnt is not very helpful. consider saving it somewhere else outside the nas.

How can I do that? Can you help me with code?

 

[Hellione]

no code, just do it manually after you changed something.
you could also add a mirror (usb-) drive to secure the boot a bit more.
beware, we are talking about the backup of truenas config, not data on the pool/s?!

Ok, thank you. My intention was to do Cron Job with daily backup, not to worry about the backup file when I make any changes to the settings. After that, I would automatically put the backup file on google drive, to be safe.

I back up the freenas configs from our (now) TrueNAS boxes to a centralized system. When we add new boxes I set up SSH key-based logins from this system and add them to the $FREENAS array below. It deletes any backups on the backup server older than $DAYS, and also sends an email summary. Feel free to use/modify as you wish.

Code:

#!/bin/bash

SCRIPT=${0##*/}
HOST=$(hostname --fqdn)
FREENAS=(freenas01 freenas02 freenas03 freenas04 freenas05 freenas06 freenas07 freenas08)

TMPLOG=/tmp/{SCRIPT}-??.log
VARLOG=/var/log/${SCRIPT}.log
RECIPIENT=somebody@somewhere.com
DAYS=30

[ -d ${DESTDIR} ] || mkdir -p ${DESTDIR}

_log() {
    printf "$(date): ${*}\n" >>${TMPLOG} 2>&1;
}

_sendmail() {
    mutt -s "${SUBJECT}" -- ${RECIPIENT} < ${TMPLOG};
}

if pushd ${DESTDIR} &>/dev/null; then
    _log "PASS: pushd ${DESTDIR}."
else
    _log "FAIL: pushd ${DESTDIR}."
    exit 1

for freenas in ${FREENAS[@]}; do
    if scp -q ${freenas}:${SRCEFILE} ${freenas}_${DESTFILE}; then

    else
        _log "FAIL: scp -q ${freenas}:/${SRCEFILE} ${freenas}_${DESTFILE}."
        exit 1
    fi
done

if [ -d ${DESTDIR} ]; then
    _log "Deleting all files in ${DESTDIR} older than ${DAYS} days..."
    find ${DESTDIR} -maxdepth 1 -type f -mtime +${DAYS} -name '*freenas*' | tee -a ${TMPLOG} | xargs rm -f;
    _log "Completed."

Thank you, I will give a try.
