      If you are using bind mounts with your container, there is a really easy way to backup before an update.

      • stop the database container
      • cp -a bind_mount_dir/ bind_mount_dir.20231019

      Then pull the latest database image and restart database container. If it works, yay, you’re done.

      If it doesn’t work, reverse the steps:

      • stop the container
      • mv bind_mount_dir/ bind_mount_dir.broken
      • mv bind_mount_dir.20231019 bind_mount_dir

      Restart container and you’re back to exactly where you were before the upgrade.
