ABSTRACT:
A system in at least one exemplary embodiment includes a source data unit and at least one backup data unit for backing up data from at least the source data unit offline. In at least one exemplary embodiment, the system includes the capability to update the source data unit once it returns to an online status. A method in at least one exemplary embodiment allows for a two stage backup where the first stage backup is to a backup data unit, which will occur in under one hour, and the second stage backup is to other computer readable medium, which can occur over a period of at least twenty-three hours. A method in at least one exemplary embodiment allows for a user to retrieve data or files from a previous backup.
