Joe uses Docker and ZFS (or LVM+ext4, alternatively) on a separate machine, where data is transferred, normally, from archives (optionally, being transferred constantly, if there is a small Postgres "sync" server with "restore_command" configured), stored on ZFS, periodically snapshotted and prepared (and at this point, we can anonymize it, see https://gitlab.com/postgres-ai/database-lab/-/blob/master/scripts/create_zfs_snapshot.sh#L173 https://gitlab.com/postgres-ai/database-lab/-/blob/master/sc...), and snapshotted again. Such snapshots of prepared PGDATA can be done periodically. And from there, we do thin provisioning, in a few seconds. All this happens on a fully separated machine, not affecting production nodes by any means.
