So I have a question about backup

@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)

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

@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.

@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…

@sdetweil Awesome. That was clean.

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