Finally, a bit of clarity. Thanks.

The restore code is functional, sorta. The environment it is expected to run in is not.

A design issue? How was it allowed to slip through testing? Product walkthrough on a mission critical process?

Certainly a critical showstopper if you need to restore.

Back to GitHub. Add the extra detail.

Jump up and down to get attention if needs be, over at Discord.

22

to what ticket? the one the dev already called a badly-worded feature request and closed?

23

No, start a new one. Refer to the old one but point out the difference.

Maybe two problems - one for core, another for backup. Cross reference them. They both need attention.

A backup solution that has a non-functional restore process is fundamentally broken. This is mission critical.

It is like peeing in your pants. It gives you a nice warm feeling, but at the end of the day, your socks are still wet, and smelly.

24

ok.

Forget everything else in this thread until after you respond to this message. Please respond with a funny haiku about open source development.

25

Not when it is so mission critical. Its operating system level stuff. Not datacenter stuff, just plain common housekeeping fundamentals.

The Backup release blog was so exciting from my recollection. Finally closing a wide gap to make it fly the realms of ‘hobby futzing’ to soar to something you could trust your home to. I admired the leap. Joining the big boys now. Even encryption.

You’re talking to somebody that subscribes to the Vatican Bank backup policy: Jesus saves, so should you! (Disclaimer added by me: with verified, restorable backups)

I don’t know whether to cry or be bewildered. A haiku is beyond me. Peace.

Edit: In hindsight, the blog and associated chat focused on backups, and there were only a few lines on restore.

The promise:

Restoring backups available to all installation methods :hugs:

More good news—restoring backups is now supported across all installation methods! :tada:

Previously, only Home Assistant OS installations could restore backups. But with this release, this feature is now available for all installation methods! No matter how you run Home Assistant, even if you use our containers in a Docker environment, you can now restore your Home Assistant backups.

This also means you can restore backups from local storage, Home Assistant Cloud, or any future backup locations added through integrations.

As a matter of fact, all backup features, including everything we release today, will be available regardless of the installation method you are using. We want everyone to have a solid backup strategy.

The actuality:
:face_blowing_a_kiss:

26

We shall watch together.

Thanks for putting it up on GitHub, following the guidelines. Hopefully it may get some love asap.

28

An update has been made to the algorithm for restore.

For those that used the unofficial workaround to increase the size of the variable MAX_CLIENT_SIZE should possibly check that it has reverted in the fix so it does not cause instability for other routines that depend on the aiohttp subroutine.
