+1 For UVB v8..
I highly recommend this for anybody looking for a good backup, v8 has seen a massive redevelopment moving away from a Windows client to a HTML5 based interface, which is probably one of the best web interfaces I've found for Backup (Unitrend's other backup software could learn a lot from this, as they currently use Flash!).
Don't take the RRP though, contact them and work out a deal. We purchased their full RMS Suite (Backup, Reliable DR etc) to cover 12 servers dual socket servers for less than £10k.
