I don't even want to think about the amount of time that I've put into Home Assistant.It's been years in the making, and losing all that effort would be heartbreaking.I take regular backups, but even this may not be enough to keep my Home Assistant instance safe.
Your smart home may have a false sense of security You have backups enabled in Home Assistant, so your instance is safe, right? If the worst happens, you can just restore from your backup and be up and running again in no time.That's the trap that most of us fall into.We believe that having backups enabled should be enough, but the reality is that for many people, it wasn't enough at all.
There are plenty of posts in the Home Assistant community forums and on Reddit from Home Assistant users who were taking regular backups, but still lost everything.Some people discovered too late that they were only taking partial backups, so they were unable to restore from the backups they'd taken.Other people had the incorrect encryption key saved for their backups, so they couldn't access them.
In every case, these users took backups and believed that this would allow them to restore everything if something went wrong.Unfortunately for them, taking a backup wasn't enough.Related I Found the Best Way to Install Home Assistant Sometimes, I forget I even have Home Assistant running because it's so reliable now.
Posts 17 By Patrick Campanale You don't have a backup until you've tested it The reality is that turning on automatic backups is only the first part of the process.You don't just need to enable backups; you also need to verify that they work.If you don't, you may only discover a problem when it's far too late.
The only way to be certain that your backups are valid is to test them.That means taking a backup and then trying to restore Home Assistant from that backup.If it works, you know that your backup is sound, but if it fails, you have the chance to find the problem and solve it before you lose everything.
Just checking that a backup file exists where you expect it to be isn't enough.As several Home Assistant users have found, the file may exist, but you still may not be able to restore Home Assistant from the backup that's saved.The best way to be completely certain that it works is to use the backup to restore Home Assistant and then verify that everything is in order.
Even if you restore a backup and Home Assistant loads up, you still have plenty to check.At a minimum, you need to ensure that your login still works, that your dashboards are all still working, that your devices still exist, and that your automations run correctly.You don't need to check everything, but testing a few things can give you a clearer picture of whether everything has been restored correctly.
Run a restore drill without breaking your real smart home Since backups can fail, as many users have discovered, it's very important that you don't test your backup on your live Home Assistant instance.If you do so, and something goes wrong, you may end up causing the exact thing you were trying to prevent and lose everything.Instead, the best course of action is to test your backups by restoring them in an isolated environment.
You can set up Home Assistant in a virtual machine, on a separate device such as a spare Raspberry Pi, or in a separate container on your homelab.You can then test your backups safely without putting your live instance at risk.Once your testing environment is set up, check that the restore accepts your encryption key, that you can log in and navigate the UI, and that your Home Assistant integrations are all available and working.
Take a look through your devices and entities to see if there's anything obviously missing and test an automation or two to verify that things work as they should.You may run into issues with two instances of Home Assistant trying to control the same device.If so, you might consider shutting down your live instance temporarily while you're testing.
Turn backup testing into a routine Unfortunately, even testing your backups in this way isn't foolproof.Things can change, and all testing a backup does for certain is confirm that the specific backup you've tested works.It's not an ironclad guarantee that subsequent backups won't fail.
That's why you should try to turn backup testing into a regular routine.You don't need to do it every day, but testing every month or two, or after any major changes, may help you to spot issues before they cause you to lose everything.It can feel like a chore, but if you think of the worst-case alternative, it's probably a price worth paying.
Taking multiple backups in different ways can also help.For example, I take backups through the native backup system, but I also take snapshots in the Proxmox hypervisor where my Home Assistant server is running, and these backups are saved to two different devices on my network as well as to the cloud.The more backups you have, the more likely it is that you'll be able to restore Home Assistant if something goes wrong.
Taking backups of Home Assistant is vitally important, but it's not enough on its own.If you don't want to end up as yet another Reddit post about how you've lost your entire setup, you should start testing your backups on a regular basis.
