Method and device for protecting data of storage device and computer system

Abstract

The invention provides a method and a device for protecting data of a storage device and a computer system. The method comprises the following steps: capturing a write operation command to the storagedevice, wherein the write operation command is sent by a client operating system which is operated on a virtual machine manager; analyzing the write operation command to acquire a write address corresponding to the write operation command; and redirecting the write address to a redirected address in a redirecting area reserved in the storage device, and performing write operations in a storage area corresponding to the redirected address, wherein the redirecting area is independent of the storage area of the data to be protected in the storage device. According to the method, the device and the computer system, the data protection for the storage device can be achieved under the condition of not adding a special hardware device and not depending on a specific operation system.

Description

technical field [0001] The invention relates to the technical field of data protection, in particular to a data protection method of a storage device, a data protection device and a computer system. Background technique [0002] The problem of data security in storage devices (such as computer hard disks) has become more and more prominent. Under the current environment, various computer viruses and system intruders may maliciously delete or modify the data in the hard disk. At the same time, users may also cause damage to data files due to misoperation. Therefore, data in a storage device needs to be protected. [0003] Solutions for data protection of storage devices in the prior art include: [0004] 1) Sampling special hard disk protection card. The scheme can keep the data in the computer storage device in a fixed state and prevent illegal tampering of the data. The disadvantage of this solution is that an additional hard disk protection card needs to be purchased a...

Problems solved by technology

The disadvantage of this solution is that it is necessary to purchase an additional hard disk protection card as a hardware device, thereby increasing user costs

The disadvantage of this solution is: additional drivers need to be installed in the operating system, and the driver needs to be customized for different operating systems, and the loading of the driver depends on the operating system, once the driver fails to load due to viruses or other reasons , the data cannot be protected and may cause other problems

For example, the computer may need to be restarted several times during the process of installing the system patch for the operating system, and the above hard disk driver may not be loaded during this process, which will cause the system upgrade to fail, causing serious problems such as blue screen
