I am studying up on CDOT, which appears to me to be NetApp's answer to virtualization. While I work through the documentation, I am ensorcelled by the concept of database recovery by means of snapshots.

I am studying up on CDOT, which appears to me to be NetApp's answer to virtualization. While I work through the documentation, I am ensorcelled by the concept of database recovery by means of snapshots.
I have never had the opportunity to try to restore/recover a database with a snapshot. To me, it sounds like the efforts of a system administrator who tried to restore and recover a production database with operating system copies of the open data files. Of course, that didn't work and much hilarity and mayhem ensured.
I'm sure that people smarter than me have figured out how to use snapshots to recover databases, but I've never been able to reason my way through the process. Does anybody know how it is accomplished?
Fond regards,
Gus
