These are policy-driven snapshot management and replication tools which use OpenZFS for underlying next-gen storage. (Btrfs support plans are shelved unless and until btrfs becomes reliable.)
If you want a ZFS root, look at https://zfsbootmenu.org/. If you want it for Ubuntu specifically, consider Sithuk's script which automates it at https://github.com/Sithuk/ubuntu-server-zfsbootmenu .

You probably do want regular automated snapshots, even if not of specific datasets. I'd recommend my own tool Sanoid for that: https://github.com/jimsalterjrs/sanoid/ ; you can configure it to snapshot the datasets you want snapshotted in the ways you want them snapshotted and nothing else.
