Failed to to call /backups/new/full - An error occurred while making backup

[Revilo91]

The problem

The following error message appears in my logs when I start a backup:

2024-12-12 13:19:51.607 ERROR (MainThread) [homeassistant.components.hassio] Failed to to call /backups/new/full - An error occurred while making backup, check job '7bbb366934e54d89b6656f7ceb507102' or supervisor logs for details

Restarting doesn't help.

Backup was created under "Create backup" -> "Full backup" (without password protection). A drive path is used to store the backups.

Same problem here

Same problem: backup doesn't work since update to core 2024.12.2

[agners]

Hm, works for me with Core 2024.12.2 and Supervisor 2024.11.4. Are you on the beta channel? Can you share the Supervisor logs?

[Revilo91]

Sure, i'm in beta channel.

here is a partial supervisor log:

Same here

[wepster]

Mine problem solved itself. Thanks to glances i saw there was python3 using a lot of cpu. I assume it was some kind of maintenance task, perkaps database purge or something. After some time cpu load dropped back to normal level and at this point i was able to create backup and for now it works fine

[yve1701]

same here. But does not solved itself.

Can you specify "some time" and "a lot of CPU"? I'm running against the same issue (30% CPU, 2 hours). The backup leaves a file 10.240 bytes large. I'm wandering if and how long I have to wait it out.

[wepster]

It was about 40% cpu usage for at least hour and a half. But it was on HP T630 (so cpu is AMD GX-420G) . If you have different hardware it can be faster/slower.
i belive (correct me if im wrong) that this is some kind of retroactive process where HA calculates statistics and/or aggregates data for period of time between when backup was made (the one i was restoring from) and now.

[bluduk01]

I too am experiencing this issue. I just updated to 2024.12.3 and it had made no change. I can make a partial backup and select everything but core and the backup will complete smoothly. It seems when I attempt to backup core only or a full backup is when I get the error.

I am running in VMware.

[bluduk01]

Just an update. I stopped core via SSH and deleted the database. Backups were once again possible however not an ideal sittuation.
