Really not an expert here but Red Hat did acquire and open source VDO from Permabit which has similar functionality AIUI.

I use subvolumes, snapshots, and send/recv functionality for cheap replication of data. Sometimes even on RAIDed disks!

There are only two file systems with that feature set today: Btrfs and ZFS. I personally prefer Btrfs because it's way more flexible and shipped with the Linux kernel.

As far as I know VDO only provides compression and deduplication. So no snapshots like in Btrfs and ZFS, although you can use LVM snapshots. Also no RAID features.
