Having equal space taken by production files and snapshots doesn't mean
every block has changed (assuming you have more than one snapshot). Each
snapshot is kept intact. So if your database changes any 1/4 of itself for
each snapshot and you have 4 snapshots, you have equal production and
snapshot space usage (assuming no dedup/compression).
Cheers, Wayne
