But you can place several DB instances, in seperate qtree's, into hotbackup mode and take a snapshot of the entire volume. Takes less time than to shutdown your DB and "waste" one snapshot per instance. Hence, you can consolidate more DB's on a larger volume (read: more spindles) and increase performance overall. Be sure to keep your redo logs on different volume! If you have different *types* of DB's, group them by how fast you can place them into a consistent state and then take one snapshot.

Good question. As far as I am aware of, a snap shot is ONLY Per VOLUME.

Is there a way to snapshot an individual QTREE from command line or must it be the entire volume. I have a volume set up for databases and I want to snapshot from command line individual QTREEs that represent different types of databases. Any help would be appreciated!
