Hi all, today I made a stupid thing.
I was trying to free up some space, because my directory /var/lib/docker/overlay2/ arrived at 4.2 GB and my Raspbian installation was going out of space. So I launched command "docker system prune --all --volumes --force", which allowed to free up over 700 MB but deleted also a couple of containers which were in stopped status.
Now I'm looking for a way to recover them, if available.
I have the system backup, created with OMV backup feature, stored as a mirrored filesystem in another drive. Is there a simple way to recover the missing containers?
For the future, I suppose I should schedule also a portainer backup... I was now reading about a specific backup procedure for the product which should be more efficient than rsync-ing the source directory.
I'm using openmediavault 5.6.16-1 (Usul) installed over Raspbian GNU/Linux 10 (buster).
Thanks in advance for your help!
