Ha Ha.
Love Kirans reply - sounds VERY salesy - also love the fact that his username is KiranQuest - most likely a sales guy directly from Quest who will of course prefer their solution!
The strap line "If you are looking for a solution that scales with your infrastructure, from a brand name vendor you definately want to take a look at vRanger" - wins it for me!
My personal opinion having used both products is that Veeam is a far more mature product. Yes, they both have the same feature set, but Veeam gets there with less fuss and confusion and will also cost you less time supporting buggy fixes and troubleshooting.
If setup correctly, vRanger does actually work, but needs some good fine tuning.
