Backup failing and huge disk IO for InfluxDB since 2025.12 | Home Assistant | Page 1

Since updating to 2025.12, this shoots in the log:

Source: components/backup/config.py:571
integration: Backup (documentation, issues)
First occurred: December 7, 2025 at 05:05:40 (4 occurrences)
Last logged: 05:17:52

Error creating backup: Error creating backup: 'BackupManager.do_backup_partial' blocked from execution, system is not running - freeze``` 

I am backing up to HA Cloud, and to my NAS via SMB. This setup has been rock solid before .12. The NAS is running fine and I can access it for media through HA.

I am also seeing huge diskread from Influx at the same time as the backup would start. HAOS/influx is running in proxmox.

Any pointers?

A manual backup to only HA Cloud fails with the same error, so can't be the NAS.
