Embodiment 1

[0023] An embodiment of the present invention provides a fault-tolerant method for a file system, which is applied to a computer operating system, such as figure 1 As shown, the method includes:

[0024] Step 101, when the operating system starts, read the pre-stored file partition table information corresponding to the operating system from the backup device;

[0025] Step 102, covering the partition table of the file system corresponding to the operating system with the read file partition table information;

[0026] Step 103, start the operating system according to the partition table of the file system.

[0027] In this embodiment, the backup device may be connected to the computer through an Integrated Drive Electronics (IDE, Integrated Drive Electronics) interface or a Peripheral Component Interconnect (PCI, Peripheral Component Interconnect) interface. Alternatively, the backup device can also be integrated with the computer; for example, the backup device can be an E...

Embodiment 2

[0033] An embodiment of the present invention provides a file system fault-tolerant method, which is applied to a computer operating system. The fault-tolerant method will be described in detail below on the basis of Embodiment 1, and the same content as Embodiment 1 will not be repeated here.

[0034] Such as figure 2 As shown, the method includes:

[0035] Step 201, after the operating system is installed, scan the file system of the operating system to obtain corresponding file partition table information.

[0036] In this embodiment, after the operating system is installed, the file system can be scanned through Basic Input Output System (BIOS, Basic Input Output System) commands to automatically identify information such as the file partition table and obtain corresponding file partition table information. But it is not limited thereto, and the specific implementation manner can be determined according to the actual situation.

[0037] Step 202, storing the acquired fi...

Embodiment 3

[0050] An embodiment of the present invention provides a fault-tolerant device for a file system, which is applied to a computer operating system, such as Figure 4 As shown, the fault-tolerant device includes: a backup device 401, a reading unit 402, a covering unit 403 and a starting unit 404; wherein,

[0051] The backup device 401 is used to pre-store file partition table information corresponding to the operating system;

[0052] The reading unit 402 is used to read the file partition table information from the backup device 401 when the operating system starts;

[0053] The covering unit 403 is used to cover the partition table of the file system corresponding to the operating system according to the read file partition table information;

[0054] The starting unit 404 is used to start the operating system by using the partition table of the file system.

[0055] The components of the device in this embodiment are respectively used to implement the steps of the method ...

Abstract

The embodiment of the invention provides a fault tolerance method and a fault tolerance device for a file system. The method comprises the following steps of: when an operating system is started, reading pre-stored file partition table information corresponding to the operating system from a backup device; covering read file partition table information on a partition table of the file system; and starting the operating system according to the partition table of the file system. The embodiment of the invention has the advantages of little backup information, short repair time, quick starting of the system, and high utilization rate of internal storage.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a fault-tolerant method and device for a file system in a computer operating system. Background technique [0002] With the increasingly widespread application of computer technology, computer systems including general-purpose computers and embedded computers have penetrated into various industries and fields, which put forward higher requirements for the security of computer systems. In many cases, due to the illegal shutdown and power failure of the operating system, the file system is damaged and the computer cannot be started normally. [0003] Currently, some solutions have been proposed for file system corruption. The Chinese patent application with publication number CN1460210A proposes a device and method for preventing damage to the computer operating system, revealing the following technical content: to partition the hard disk, the first storage area is an in...
