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.
