Corporate Backup were my last resort after a number of broken promises and awful software from other, supposedly reputable vendors. I wish I'd gone to them first.

They made some big claims over the phone, but after 4 weeks of trialing it was obvious that they could do everything they said they could do!

Files, system state, exchange, active directories, exchange, SQL, VMware, HyperV to start with,
plus file sharing capabilities, online signup for my clients....

Best software I've ever purchased. hands down.

P.S I've only used the windows version, but I'm sure the Mac version is good too :)
