If that's what the paper says! Please remember my comments were from "vague memory".

DownSouth - re: "So the Snapshots are volume copies + incrementals" No, the opposite. The map of data covered by the snapshot is saved, not the data - as in the NTAP process, this is a quick and lightweight operation. Changes to that state are tracked. No one actually copies the data in any of these snapshot schemes, that is way too heavy. They are all based on capturing the map of affected data and maintaining original state for anything that changes. The differences are in how the state is captured and mapped, and whether the change log tracks the original data or the current state of the data. BTW this may or may not have anything to do with SUNW's product...
