Depends on your storage backend, all backends except the directory one
will use copy-on-write for deltas from the image used for the container
and their current state.

If using ZFS and have quite a bit of spare RAM you can also turn on
deduplication on your ZPOOL which will then deduplicate writes as they
happen, possibly saving you a lot of disk space.
