(57) how to hold onto a recording medium a record of changes to the [summary] data, it is possible to reconstruct the state of the medium in the previous time have been described. Other embodiments are also provided in order to improve this process, to improve. This includes keeping the RAM in two copies of the data are compared to detect contamination before being transferred to the recording medium, the separation of the logic and views protection, incompatible software Insert the delay as necessary and, to ensure that you flush the write cache by ensuring that it hides the disk in order to be protected from, and that a certain amount of time has elapsed, that free time has elapsed By the, to flush the write cache, inserting safe points after the speed of the disk activity is reduced, be inserted periodically safe point, the need to set a safe point for one user it is possible to separate the user activity to flush the OS entire cache after it is detected, by monitoring the files and directories to be reconstructed approximately from the table at the time of contamination, are organized sequentially linked complex thing, you want to run the engine using the data structure was is included.
