Unknown error when creating back-ups

human_or_coffee · April 16, 2023, 4:58pm

Hello all, I’m hoping someone can point me in the right direction. When I try to create back-ups manually from the Settings -> System -> Backups menu I’m getting an Unknown Error.

When I look in the log I see:

2023-04-16 09:47:07.283 ERROR (MainThread) [homeassistant.components.websocket_api.http.connection] [546959012912] Error handling message: Unknown error (unknown_error) User from 192.168.1.233 (Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/111.0.0.0 Safari/537.36)

  File "/usr/local/lib/python3.10/tarfile.py", line 256, in copyfileobj
    raise exception("unexpected end of data")
OSError: unexpected end of data

There is a .tar getting created, but it’s only 10240 bytes which I believe is the minimum size for a tar. Also when I try to de-compress it, there’s nothing there.

~/web_services/home_assistant/home_assistant_config/backups > ls -l 23e07b68.tar 
-rw-r--r-- 1 root root 10240 Apr 16 09:47 23e07b68.tar

A little bit about my system:

Running in a docker-container on a Raspberry Pi 3
Running Home Assistant 2023.4.1 w/ Frontend 20230406.1 - latest
Otherwise, home assistant is functioning totally normally and working

I’m not totally sure how to troubleshoot this or where to go so any advice is much appreciated. Thanks!

Update to 2023.4.4 first.

Will do, I didn’t realize that new releases occur on the first Wednesday of every month.

Has something changed in terms of the HA database, maybe that’s the problem.

Okay, I updated to 2023.4.4 and am still seeing the same error. Any idea how I would check if something about the HA database changed? I haven’t consciously or intentionally changed anything.

same issue of “unknow error” when try creating a backup

I had the same.
With me the error occurred because in config folder there was a folder/file which could not be read. In my case .bash_history.
With chmod a+r .bash_history i gave everyone read permission. Now backups works.

I can confirm the cause and the cure (2023.11.3).
My file with wrong permissions was:

/home/homeassistant/.homeassistant/data/.storage/onboarding
