I need to set up a backup system for several retail store systems. Each system runs various types of software that are each critical to the operation of the business. What are my best options for doing continuous, full system backups that will not "get in the way" of the business operations? I would need to have the ability to restore part or all of the system should any crash occur and, ultimately, would like to be able to choose from multiple restore point options.
I have thought about using Ghost, or some similar, imaging software, but I am not familiar with those products and not sure if they offer the features/functions that I need.
