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
