Problems solved by technology

[0004] Since the data in the master boot sector needs to be copied to the memory when the computer or virtual machine is started, the computer or virtual machine cannot detect it in time when the data in the master boot sector is damaged during the running of the computer or virtual machine , only when the computer or virtual machine restarts and fails to operate normally can it be known that the data in the master boot sector is damaged, resulting in the failure of the computer or virtual machine to recover the data in the master boot sector in time
In order to ensure the normal operation of the computer or virtual machine, it is very important to restore the damaged data in the master boot sector in time, but at present, there is no data recovery method for the master boot sector

Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them.

[0031] In order to restore the data in the master boot sector in time when the data in the master boot sector is damaged, an embodiment of the present invention provides a method for recovering data in the master boot sector, which can be but not limited to be applied to a computer or a virtual machine , the flow of the method is as follows figure 1 As shown, the execution steps are as follows:

[0032] S11: Detect whether the master boot sector stores the first setting identifier.

[0033] Under the normal situation of the data of the master boot s...

Abstract

Embodiments of the present invention disclose a master boot sector data recovery method and apparatus. The method comprises: detecting whether a master boot sector stores a first set identifier; if the master boot sector does not store the first set identifier, detecting whether a reservation storage space stores backup data of the master boot sector; if the reservation storage space stores the backup data of the master boot sector, determining that data of the master boot sector are destroyed; and recovering the data of the master boot sector according to the backup data in the reservation storage space. According to the scheme, when the data of the master boot sector are detected to be destroyed, the data of the master boot sector can be recovered in time, thereby ensuring normal user service processing.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data recovery method and device for a master boot sector. Background technique [0002] Master Boot Record (MBR), also known as Master Boot Sector, is the first sector that must be read when a computer or virtual machine is started to access a disk. The master boot sector records information about the disk itself and the size and location information of each partition on the disk, and is an important entry point for data. [0003] If its data is destroyed, the basic data structure information on the disk will be lost, and the computer or virtual machine will not be able to operate normally, and thus cannot process user business normally. In practical applications, due to objective reasons or human reasons, the data in the master boot sector will still be destroyed during the operation of the computer or virtual machine. [0004] Since the data in the master boot sector need...
