It allows me to expand disk size fairly easily when needed. So i use 8gb as initial size instead of 30gb. Offcourse overlay2 works fine on it. You can handle snapshots/backups via ZFS itself! The volume is just another object on your zfs pool, so whatever you use for managing it can work with volumes as well. Eg I use Sanoid for my snapshot management (and included syncoid for remote replication) Now install docker, then portainer.
