Stop home assistant for backup

Hi,

My goal is to stop hassio temporarily, while dd backup is saving the entire disk of my pi. I installed hassio via the hassio_install script on top of an existing raspbian installation and it is running in docker. If I don’t stop it, it is very likely that the sqlite database becomes corrupted.
I saw that there are several docker containers, one for home assistant, one for the supervisor and one for each addin. If I stop the hassio-supervisor.service via systemctl, the container will stay down. If I stop docker.service too, all container will go down. When I start them back up only the supervisor and home assistant containers will come back, but none of the addin’s containers are started. Is it enough to stop only supervisor and home assistant containers and let the addins running? Can they corrupt the backup themselves? If they should also be stopped, how can I make them come back, along with supervisor and home assistant containers after the backup is finished?

Thanks
