iBac 4.0 for Windows has been developed to speed up and simplify the job of backing up critical data. Imagine if each day you could parse every file in the enterprise and only back up those that have changed since the last backup was run. This would save enormous amounts of time compared to the traditional backup method that involves backing up entire files, databases and objects each time a backup is run regardless of whether they have changed from the previous backup. iBac 4.0 for Windows introduces a new medium for data protection and retention that logically addresses the process of backing up mission critical data.
