Traditional backup tools work based on time intervals of hours or days. Between these intervals, documents and files suffer a lot of changes that must be reflected during the next backup run. Identifying the changes and its corresponding copy is a tough and demanding job for the computer, ending up in most cases monopolizing the resources, preventing the user to do anything at the same time.
With CDP we forget the traditional backup
A modern backup tool should work in a continuous manner, processing th smallest changes as they happen, instead of waiting for the next interval. This way, the workload is lighter, and the process is more manageable and less hampering, as it would use a very small part of the computer’s resources, in a steady way, instead of almost all the resources every now and then.
“Continuous Data Protection” (CDP) is a technology to manage the smallest changes in the hard disk as they occur, almost simultaneously with the change, without the user even noticing it. This way, the users ends up forgetting that its own computer is performing the protection task all the time. In case of problems, they can go backwards and forward in time intervals of minutes or even seconds, to find and download documents and files as they were in the moment the users require.
In summary, traditional backup tools force the users to stop working, while modern tools should make them forget completely of the need to make backup, and allow them to use time and mind in most important things, including family and time off.
