MULTI-POINT DATA RECOVERY METHOD AND SYSTEM, AND OF RECOVERING DATA COMPUTER READABLE MEDIUM STORING THE SAME}

The present invention relates to a multi-point data recovery method and system and a computer-readable recording medium storing the same, and more particularly, to reduce the total cost of ownership (TCO) incurred in time and cost loss. A multi-point data recovery method and system and a computer-readable recording medium storing the same.

In recent years, in various computer systems using operating systems such as Windows and Unix, if the operating system, applications and data of the computer system are lost due to a user's mistake, virus, or malware, in some cases, the fatal computer system In some cases, failures can cause computer systems to become unusable, in which case it takes longer to troubleshoot and recover from problems, and can result in significant loss of time and money for individuals and system users.

In the past, in the event of a computer system failure, most ordinary users who are not familiar with the system or the computer had no choice but to take the repair to a professional repair staff. After formatting, I had to reinstall the operating system.

However, formatting the hard disk and reinstalling the operating system was not only time-consuming, but also a very cumbersome and time-consuming task, such as the need to reinstall various applications even after installing the operating system. In addition, if the hard disk is formatted, all the data stored by the user up to then will be lost, and the user may suffer too much loss.

Therefore, with the recent increase in the popularity of PCs and almost everyone using the PC and the Internet, each user can recover the system to its original state more easily and quickly when an abnormality occurs in its own system. In addition, in such cases, there is an increasing demand for a way to easily and efficiently back up their data to prevent the loss of stored data.

However, until now, the recovery method of a system such as a PC has been installed on a PC or a user's own PC by using a recovery program downloaded online or offline and stored on a CD or disk. It may be a problem, and even after the installation, the use of the program is complicated, and it is inconvenient for the user to properly use the recovery program.

In addition, recently, recovery programs that are automatically executed without a user's special instructions have been developed. However, most of them make the product shipped with the factory. That is, after the recovery, only the operating system and the minimum required utilities are installed. As it is, I couldn't recover the data saved by the user.

As a result, users had to back up the data they had stored separately, and then had to recover the data after restoring the operating system. At the same time, they needed to prepare and manage another storage medium for backup. There was discomfort that there was.

In addition, recently, a backup program has been developed to backup the contents stored on the hard disk into a single CD at a time, and restore them to the state at the time of backup by using them when an error occurs, but it is also difficult for general users who do not know the computer This is the same as the above, in that the backup contents are limited by the capacity of the CD, and at least the user must manage the storage medium in which the CD is stored.

Therefore, it is desirable to provide a method for recovering a system that can simultaneously solve the recovery of the operating system and the backup of data without the user having to manage a separate storage medium, etc., but there has been no data recovery method that satisfies such a requirement.
