No, sounds like you have it about right. Also, unless you have snapmanager for Oracle you're going to want/need to script putting you DB in hotbackup mode anyway, to get a consistent snapshot of it for mirroring off-site. Depending on your platform, OS and drivers you use you may also be out of luck with getting snapdrive to even work. I've been unable to get it to work on our Solaris infrastructure because the FCP drivers we use aren't supported by Netapp and don't work with snapdrive. It just segfaults. So even if you want to use it make sure your stuff is supported by it. But in the end I've found that I made some scripts which do the job more than adequately for us.
