So I have a question about backup

Ray

I’m currently running my magic mirror on a Linux based system
I want to back it up in case something goes wrong

can I just clone all my modules and store them in a safe place
including config, tokens, credentials
then reinstall magic mirror the traditional way
then copy all My modules into the folders
then use npm install in each modules folders

Would this method work without causing any problems?

sdetweil

@ray yes, that will work.

save config.js

u can save the module folders, or save the list of modules to install,

git remote -v
will list where u got the module from
so u can git clone/npm install on restore
with the config.js

Ray

@sdetweil that’s fantastic. I appreciate the quick response. I put a lot of effort and time in this mirror
so is good to hear. I can back it up safely

Ray

@sdetweil forgot to ask
so the git remote -v
we’ll get all its information from my original config.js
is that correct

sdetweil

@ray you do that in each module folder
the info from config.js is settings and API keys for each/all the modules

my grandson just went home from.sleepover. I can write a quick script to backup and restore

sdetweil

@ray i created two scripts mm_backup and mm_restore
you can get them here

they write/read from a folder (defaults to ~/MM_backup )

using ~/MagicMirror as the source (default)

(but take parms to change the names) see mm_backup.sh -h

this creates a git repository of the 2 files and creates a tag (label) for the instance of the backup.

you should create a (free) private repo (to keep any config settings private) on github and push the local repo there to have an offline backup
then u can clone it anytime and restore from the appropriate tag (date/time)

Hi Sam. Here? I checked your Github and nothing there either. Or maybe I am missed it?

sdetweil

@mumblebaj doah!!.. forgot the link

@sdetweil Awesome. Thanks Sam. Always nice work from you.

@sdetweil When I ran the mm_backup.sh I saw this error but it created the output in the MM_backup folder as expected.

usage: git init [-q | --quiet] [--bare] [--template=<template-directory>] [--shared[=<permissions>]] [<directory>]

    --template <template-directory>
                          directory from which templates will be used
    --bare                create a bare repository
    --shared[=<permissions>]
                          specify that the git repository is to be shared amongst several users
    -q, --quiet           be quiet
    --separate-git-dir <gitdir>
                          separate git dir from working tree

Is this because of some options that I did not specify? After the output was created I just manually pushed to a private directory on git.

sdetweil

@mumblebaj probably git version before 2.28

the primary branch name option didn’t come in til 2.28. 0

i have

git --version
git version 2.34.1

I will add a check…

to upgrade git (don’t do it for these scripts… I have fixed the script to not need this capability, just documenting how)

sudo add-apt-repository -y ppa:git-core/ppa
sudo apt update
sudo apt install git -y

sdetweil

@mumblebaj I pushed a change to set the primary branch name a different way…

give it a try

backup to some other folder (and then u can delete that folder)

./mm_backup.sh -b somefolder

just pushed a change to create the output folder if it doesn’t exist, instead of error…

mumblebaj

@sdetweil Awesome. That was clean.

mumblebaj

@sdetweil My git version is 2.20.1. Guess I need to update it.

sdetweil

@mumblebaj said in So I have a question about backup:

Guess I need to update it.

only if u need something

mumblebaj

@sdetweil Right now, not. MM runs perfect as is. I’ll leave it for now. :beaming_face_with_smiling_eyes:

sdetweil

@mumblebaj i don’t want to force people to upgrade, thanks for the report and test results

mumblebaj

@sdetweil No worries and a pleasure.

Ray

@sdetweil hey thanks a lot. I appreciate that
I will definitely check it out
I kind of made my own. It’s very basic but seems to do the trick
it is menu-driven so I can choose which modules I want to backup or restore
I’m fairly new at writing scripts. They are a lot of fun
