Unitrends...
Was a happy PHD Virtual Customer, was then a happy Unitrends customer (after they snapped up PHD Virtual), now a very p*ssed off Unitrends as they're discontinuing the PHD VB / UVB product.
They're pushing customers across to UEB, which for a purely virtualised environment sucks. not least because it has a Flash interface, and misses many of the best features of UVB.
