Next decision - this is a system backup. Bacup copy the information entirely, or completely volumes or individual files and folders, and that takes plenty of time, depending on the amount of copied information. This is a more reliable means for solving the problem, as there is always an opportunity to correct itself the result of destructive activities, whether it be a virus or simply unskilled users. But not always notice in time that such activities took place be, especially if there has been no change in fatal and easily change the settings of important programs or other resources. If you suddenly notice that Windows has become unstable. Became slow computer, appeared advertising modules in your browser, and some programs start or have ceased to behave poorly, there is a word interference of the virus or wrong user actions. In this case, the user gets his own, pre-established backup, image to disk, and restores from the system to a previous state. That is, simply returns the time the state of your computer or files. Bacup not require a permanent connection to the Internet. They do not need updating, as there are no databases. This is a simple tool in the hands of an experienced user, because only the discriminating user will be able to port the backup images to third-party carriers, and be sufficiently skilled to use them in case of emergency. This is of course difficult to use such a system for novice users who wish to protect your system. Additional solution are firewalls. They are mostly guarded ports - filter the traffic to flow through the network interfaces (network cards, modems). Opening and closing the port is considered as alteration of the information, namely, how to stop access to network applications, and this information is stored on hard disks, disk arrays. However, in the case of intervention of the human factor, they naturally will not help. The final decision are programs that use technology to shadow drive. This solution is now software Disk Write Copy. This is more a technological approach to protecting the efficiency of the operating system because the system itself works in the copy on the original. Anyway, that make a system disk image and store it on a shelf for recovery in case of failure, but not spend too much time on it and not engage in the restoration itself. This program works as an automatic backup. We are lazy and do not like to waste time on boring, regular recovery operations. Moreover, we may not be able to use it skillfully. Disk Write Copy is an improvement over the anti-virus, the solution in the sense that regularly removes any effects of unauthorized modification of viruses, outside visitors, improper operation by inexperienced users, causing the computer to its original state of each session. As with backup, Disk Write Copy does not require updates, and connect to the internet to work. Do not scan incoming information, so completely does not load the computer through their actions and not take up much space. More perfect than the usual backup, because it enables us to include the protection of a few clicks of the mouse and automatically restores the entire system with all files every time you boot your computer, no longer requiring the user to no knowledge. It looks like what you just did not notice any difference in speed and performance, and your computer, starting each day will be 100% as clean of viruses, as fast and with the same settings as before, when you only included the protection of the disc. What is particularly interesting, on the protected disk no longer have to perform a defragmentation if you made it before turning on the protection, because the disk will be defragmented as well, as always, and access to the files will be faster, just have a positive impact on the performance of your computer and your time. Why time? And you no longer have to spend it on the management of backup, waiting to load an image of 5,15,30 or more minutes to clean the registry and temporary files folder. You can forget about what is to reinstall Windows and how long it takes. Today is the time - is money, and Disk Write Copy them to save. An interesting feature is the fact that the program that uses shadow wheels, not ask you to set aside space on the disk, or on another carrier. Through proprietary technology, all changes are recorded in unoccupied sectors filesystem on the hard drive and cleaned after each use. Surprising how much free time you can spend on your business!
