No personal dealings with that product. I've found that most of these magical storage solutions do not understand

• Oracle DBs tend to be large, as compared to the mindset of huge quantities of small files most backup tools handle;
• Oracle DB blocks are (usually) made up of multiple disk blocks, and simply capturing the disk blocks does not guarantee DB block integrity;
• they grab the temporary tablespace, which is throw-away and is often uncomfortably large, therefore possibly a waste of time to grab.

My approach is to ask the storage or backup vendor for white papers specifically related to Oracle [version] backup/snapshot tests. If they have those white papers, then look for the answers to those last-two specific problems.

If they can't provide white papers, my impression is they probably don't have experience.
