Have you ever experienced this moment? You're sitting at your dashboard in the evening, \u201ejust for a moment\u201c changing a line in your configuration.yaml<\/code> or in a complex automation system - and suddenly nothing works anymore. The screen turns red, error messages fly around your ears, or worse: the automation that has been running perfectly for months simply stops working. away<\/em> or overwritten.<\/p>\n\n\n\n

The classic Home Assistant backup is great, but it's often like shooting sparrows with cannons. Do you really want to restore the entire system from tonight at 3:00 a.m. and lose all the data (energy consumption, statuses) from the last 12 hours just because you have one<\/em> file messed up?<\/p>\n\n\n\n

Here comes the Home Assistant Time Machine<\/strong> into play.<\/p>\n\n\n\n

In this ultimate guide, I'll show you how to install, configure and use this ingenious tool. We'll look at installing it as an add-on (the easiest method) and as a standalone container (for the Docker pros).<\/p>\n\n\n\n

For detailed instructions and explanations of all configuration options, I recommend watching the YouTube video linked below. This video goes into detail about each individual setting, providing you with comprehensive instructions on how to set everything up correctly. Any code from the video can be found in this article, so you can use it directly without having to type it out.<\/p>\n\n\n\n

This blog post, including video, is part of a series in which we build and set up our own home server. We start with the basics, such as installing Ubuntu VM with Docker, and then move on to configuring our own domain, security measures, and, above all, lots of cool and useful self-hosted services. Whether it's media servers like Plex or Jellyfin or document management like Paperless-NGX, we'll work together to build the setup you want to see. We'll even tackle topics like single sign-on (SSO) together.<\/p>\n\n\n\n
