I watched their presentation and tried their demo today. The current version seems to me to be not quite as user friendly as Nine's offering, which I'm pretty impressed by.
Servosity is touting their upcoming release though that sounds impressive. Network, bare-metal backups using StorageCraft's technology, subscription pricing, an unlimited storage consumer option... They say it should be out in the next 1-2 months. Who hasn't heard that from a software company, I know, but if it happens it sounds worth looking at again.
