Hi,
Yes, it’s a good solution that works great once installed.
To build my MM, I have made some modifications on everywhere to obtain the result I want, and if i had to rebuild all it will take a lot of time because it’s impossible to remember everything (like modifications on boot.txt)

And I agree about SD Card. It’s a really difficult to preserve it. So the solution is to externalize backups.
I’ve a NAS server with NFS possibilities. I think I’ll build a script to save every night for example a backup of config.js, custom.css, compliments.js and boot.txt (to compare in case of rebuild).
But, i’m also agree is represent a lot of work for a system that not modify every day. A big backup on every major modification is sufficient.

Have a nice day.

@bkeyport thanks. my backup doesn’t copy custom.css… doah

Just scripted what I want. Not externalized for the moment. Just a simple copy of modules folder and personnalized files.

Sorry if it’s not perfect, but i’m not a developer :)

#!/bin/bash

#BACKUP FOLDER
mkdir -p /var/backups/MM
cd /var/backups/MM

#OLD BACKUPS PURGE
echo "--- PURGE TASK ---"
echo "Check for existing backups..."
nb_save=$(ls | wc -l)
if [ $nb_save -gt 4 ]
then
        oldest_folder=$(ls -lt | tail -1 | cut -d " " -f10)
        echo "Limit of 5 backups reach. Deleting of the oldest one : $oldest_folder"
        rm -rf "$oldest_folder"
        echo "DELETED."
else
        echo "Limit of 5 backups doesn't reach, skip to backup task."
fi

#BACKUP
echo "--- BACKUP TASK ---"
echo "Starting..."
d=$(date +%Y-%m-%d_%H:%M)
mkdir -p $d
cd $d
cp /home/pi/MagicMirror/config/config.js config.js
cp /home/pi/MagicMirror/css/custom.css custom.css
cp /home/pi/MagicMirror/modules/default/compliments/compliments.json compliments.json
cp /boot/config.txt config.txt
mkdir -p modules
cp -R /home/pi/MagicMirror/modules/ .
echo "DONE. CURRENT LIST OF BACKUPS :"
cd ..
ls -A1

@selyjohns cool… mine saves the list of modules (git url) and config.js to a local git repo with a tag with the date

other files (compliments.json) … cool… (any reason u didn’t put those in config.js?, u have to restart to use an updated file too)

Perfect :) Git seem to be a good solution. For next evolution haha
For the json, it’s because i’ve define a lot of compliments and it’s more clean on external json that in config.js

sdetweil

@selyjohns you can look at my backup script for creating the tag from the date/time

@sdetweil Perfect ! Thanks :)

@sdetweil Whoops. that’s 90% of my mirror! Without CSS copied it becomes a big mess quick. Only modules I don’t have custom CSS for is MMM-Multimonth and MMM-Worldclock (Hmm, wonder why? 😀)
