Listening to all the hardware vendors, you would think that virtualization is the greatest thing since sliced bread... It is true that it solves a number of problems, but it also comes at a price. For example, many organizations maintain historical backups. Suppose I use the facilites of my virtual storage to do some reoganizing. How do I then trace the files that I have - in their new locations - back to their ealier backups? You can't. At least you can't without NTP Software's technology. Does it matter? It matters to a lot of our customers. In fact, we work with clients who refuse to reorganize their storage for just this reason. The bottom line? Everything comes at a price...
