I haven’t run out of storage, it’s got a TB free at the moment.
The cloud backup is doing it to me with no way to force stop. 12/8/2025
I disabled HA cloud, never really needed as I backup to several places.
SSH into HA=> ha core reboot
This reboot allowed me to get restart function back but failed backup error still there
EDIT: I did restart a backup and was successful which removed above warning
