RE: NetApp flier - based snapshots and db backups

That's correct. What's very exciting about Netapp snapshots, too, is that if you get the FlexClone option, you can make multiple read-write copies of your snapshots, and those copies only take up as much space as the data that is changed. So, you could give each developer a full copy of your production database, and assuming they're not going to change a lot of data in the database, they can run it to their heart's content. Then, every week, or every few weeks, destroy and recreate the snapshots from production.

Very cool stuff.

Just to help clarify, and make sure I understand correctly - I think what you're both saying is that you could use the copied data, control and online log files to start another copy of the database instance, which would then perform crash recovery, i.e. roll forward through the online logs and then rollback any uncommitted transactions. However you could not apply any archived logs to the copied database. Please let me know if I've got it wrong.  

Thanks,
Brandon
