Update:
I’ve run several tests, but unfortunately, the backup keeps causing problems.
Apparently, the backup process restarts sporadically in the background, and memory usage fluctuates between 85 and 100 percent.
The backup itself isn’t being performed correctly or completely.
This morning, I couldn’t even launch any applications, despite not having made any changes to the system.
Error: “Cannot connect to the Docker daemon at unix:/var/run/docker.sock. Is the docker daemon running?” (Yes, I tried to restart and reenable docker.socket, but issue clouldn’t be fixed)
I’ve now rolled back to version 1.6.2, and everything is running stable again.
Unfortunately, version 1.7.0 seems to still be in beta.
