Automated repository backups

[per1234]

This stems from a forum discussion where @kdschlosser expressed concern over our reliance on GitHub to preserve the valuable data contained in this repository.

Although it is unlikely that something will happen to GitHub that would cause a data loss it is certainly possible and it would be tragic to lose any of our work. It should be fairly easy to implement an automated backup of this repository, as I understand is already be done with the EventGhost forum content.

There are two types of data in this repository:

• Git repository - Can be backed up by a simple git clone https://github.com/EventGhost/EventGhost.git, which will back up the default branch (master). After the initial clone the repository can be updated by git fetch. If we were to go back to using the GitHub wiki for any reason it can also be backed up by the same method as the wikis are actually just Git repositories.
• GitHub data not contained in the Git repository (issues, PRs, comments, labels, etc.) - Some strategies for backing this up are detailed here: https://help.github.com/articles/backing-up-a-repository/
