Problems solved by technology

The disadvantages of this solution are: need to use third-party software; cannot carry out continuous data backup protection for data; each backup needs to back up the entire system partition, and the backup data after multiple backups will take up a very large disk space
Each backup requires the user to restart the computer first, and then do incremental backup, so real-time data protection with smaller granularity cannot be achieve

Embodiment 1

[0062] The method for backing up and protecting hard disk data in the computer system described in this embodiment is based on virtual machine technology and is applied in a computer system with a guest operating system installed. The computer system includes a first hard disk, a second hard disk, and a virtual machine management system. server, and at least one guest operating system running on the virtual machine manager. Such as figure 1 As shown, the method for backing up and protecting the data of the storage device in the computer system described in this embodiment specifically includes the following steps:

[0063] Step 11, performing original data backup processing on the original data of the first hard disk, generating original backup data and storing it in the second hard disk.

[0064] Here, the original data is existing data on the first hard disk when the original backup process is performed, and the original backup process may be a 1:1 backup of the original da...

Embodiment 2

[0094] Since the writing operation of the guest operating system may be very frequent, the above-mentioned embodiment 1 may need to save a large amount of operation information in the second hard disk. For the convenience of management, this embodiment further combines these operation information and stores The operation information of the data is combined to form a record block, and data recovery is performed based on the record block. In this embodiment, the first time corresponding to each operation information in the record block can also be deleted, so as to save the storage space of the second hard disk.

[0095]The method for backing up and protecting the data of the storage device in the computer system described in this embodiment specifically includes the following steps:

[0096] Step 31, performing data backup processing on the original data of the first hard disk, generating original backup data and storing it in the second hard disk.

[0097] Step 32, after gene...

Embodiment 3

[0123] The method for backing up and protecting hard disk data in the computer system described in this embodiment has the same application environment as in Embodiment 1, and is specifically applied in a computer system with a client operating system installed. The computer system includes a first storage unit, a second A storage unit, a virtual machine manager, and at least one guest operating system running on the virtual machine manager. The method for backing up and protecting the data of the storage device in the computer system described in this embodiment specifically includes the following steps:

[0124] Step 51, obtaining the write operation command of the at least one guest operating system to the first storage unit, and recording the first time when the write operation command is obtained;

[0125] Step 52, judging whether the original data backup of the first storage unit is stored in the second storage unit: if yes, proceed to step 54; otherwise, proceed to step...

Abstract

The invention provides a method for carrying out back-up protection on the data of storage equipment and a computer system. The method comprises the following steps of: obtaining a write operation command of at least one client operation system for a first storage unit; recording the first time for obtaining the write operation command; carrying out write operation on the first storage unit according to the write operation command, wherein the write operation is used for writing first data at the first address of the first storage unit; and writing the operation information corresponding to the first time and the write operation command onto a second storage unit, wherein the operation information comprises the first address of the first storage unit corresponding to the write operation command and the first data corresponding to the write operation command. The method can realize continuous data back-up protection supporting the concurrency of multiple operation systems, without depending on the operation systems and third-party software.

Description

technical field [0001] The invention relates to the technical field of data backup protection, in particular to a method for backing up and protecting data of a storage device in a computer system 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, it is necessary to perform backup protection on the data in the storage device, so as to recover the damaged or deleted data when needed. [0003] In the prior art, the schemes for data backup and protection of storage devices in computers include: [0004] 1) Use hard disk backup software such as Ghost to back up the entire system partition to the hard disk. The disadvantages of this solut...
