    @sdetweil said in Question about backup script:

    hm… I did

    Dear Sam (@sdetweil),
    yes - this worked for me as well :-)

    Now figured out how it works:

    Have issued

    bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_backup.sh)" -r https://github.com/rkorell/MagicMirror -p 
    

    Then I was asked for username and password (twice) and git upload worked…
    It seems git upload now contains a copy of local directory mm_backup.

    If I check both, there are only a few directoris in Github as well as locally - much fewer than total number of installed modules…
    What is the criterium for a module to “earn” a directory or not?

    Thanks a lot!

    Warmest regards,
    Ralf

      @rkorell the backup copies the url of the module source

      where you cloned from,
      see git remote -v in any module folder

      now some modules create files, token.json for example
      if i find extra files i need a place to store them, so the module name for a folder is created

      the module_list file contains the list of modules needed
      and their urls. they are reinstalled

      the readme says this

      this is not a binary backup

      you can use this to move to a new system or new sd card (changing processor architectures too, pc to pi, pi to pc… whatever)

      yes the folder MM_backup by default is a git source repository
      and git will track any changes (new backup differences)

      each time you back up, i create a marker to label this event, in git called a tag

      and you can restore any one of those and compare two tags to see the difference

      the private repo is because the files are saved in source form, and contain apikeys and maybe other credentials

        @rkorell you got prompted twice for username because git needs to know who you are and how to reach you if there are concerns about your “commit” to the repo. you csn see this in git log
        output in the backup folder
        this is username and email address

        then the push , github needs to know . this is the password prompt from git

        you could use git config to save those, and avoid the prompts

          Sounds cool.
          How can I do this?

          Thanks!

              Thanks for this explanation - this is what I had assumed.

                OK, thanks.
                I had understood that this is a config of your scripts, sorry.

                  @rkorell no… you can store config settings for git (the source code repository tool MagicMirror uses and most modules use (…git clone))
                  and the way to make the repository that the backup uses

                    @sdetweil as far as google told me it seems, I need to install Git CLI - which is not easy available for Raspi.

                    Any hint?

                    Sorry!

                      O.K,. Google is not my friend today…
                      It seems that a “.gitconfig” file will do the trick …
                      Will double check.
