We are currently with 5 branch offices doing tape backups and we're not with IT so getting someone to replace tapes is been unreliable. I'd like to see about putting an appliance based solution in and I just looked at Quantum DXi4000 and 6700. Is anyone familiar with this solution and can offer any pro/cons from their experience. We are also going to look at Data Domain. I'm not sure if there are others to review, but I'd like to find something others highly recommend and maybe using.
