You can, indeed, achieve similar level of magic of a general purpose savings
with ZFS or BTRFS.
I'm using BTRFS snapshots to keep intermediate copies of a working partition.
It's nearly 400GB of data, and I keep ~10 copies of it (a week worth of daily
plus 3 for month of weekend copies). All on ~800GB of RAID6 space.

I can imagine so.
