Description
Technical field
The present invention relates to data backup resist technology field, be specifically related in a kind of computer system, the data of memory device be carried out method and the computer system of backup protection.
Background technology
In memory device (as hard disc of computer), the safety issue of data is more and more outstanding.Under current environment, various computer viruses and system invader may carry out malice to the data in hard disk and delete or revise, and meanwhile, user also may be because of maloperation, the destruction that causes data file.Therefore, need to carry out backup protection to the data in memory device, so that recover data damaged or that delete in needs.
The scheme that prior art is carried out data backup protection to the memory device in computing machine has:
1) use the hard disk backup software such as Ghost, backup in hard disk system partitioning is whole.The shortcoming of this scheme is: need to use third party software; Can not carry out lasting data backup protection to data; Each backup all needs whole system subregion to back up, and repeatedly backs up later Backup Data and will take very large disk space.
2) utilize incremental backup software, the BACKUP TIME point arranging according to user, gets off the data backup changing in hard disk.This scheme need to be used third party software equally, and needs the incremental backup of doing of user's active.Each backup all needs user first to restart computing machine, then does incremental backup, therefore cannot accomplish the real time data protection that granularity is less.
Above-mentioned two schemes has following common shortcoming: all can not realize lasting data protection; By the third-party software operating in operating system, realize data backup protection, so data backup depends on operating system; While moving a plurality of operating system in computing machine, cannot realize data backup protection to a plurality of operating system simultaneously simultaneously.

Embodiment
For technical matters, technical scheme and advantage that the embodiment of the present invention will be solved are clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
< embodiment 1>
The method of the hard disc data backup protection described in the present embodiment in computer system; based on virtual machine technique; be applied in the computer system that client operating system is installed, described computer system includes the first hard disk, the second hard disk, virtual machine manager and operates at least one client operating system on described virtual machine manager.As shown in Figure 1, in computer system, the data of memory device are carried out the method for backup protection described in the present embodiment, specifically comprise the following steps:
Here, described raw data is to carry out original backup existing data on the first hard disk while processing, and it can be raw data to be carried out to the backup of 1: 1 that original backup is processed.Raw data back-up processing can be to carry out in advance in the described computer system Qian You producer of dispatching from the factory, and can be also by user, initiatively to be initiated in user uses the process of described computer system.
Here, obtain described write operation order, can be that virtual machine manager goes to tackle the write operation order to the first hard disk that client operating system sends on one's own initiative, can be also to go passively to receive by virtual machine manager the write operation order to the first hard disk that client operating system sends.Because client operating system all needs through virtual machine manager the read-write operation of hard disk, therefore, in the present embodiment, by virtual machine manager, obtain the write operation order of any client operating system to the first hard disk.Can find out, this acquisition operation does not rely on any third party software being arranged in certain operating system.
Here, virtual machine manager, when described the first hard disk being carried out to write operation according to described write operation order, can synchronously be kept at operation information corresponding to this write operation order in described the second hard disk.Certainly, virtual machine manager can also first be cached described operation information, be kept in buffer area or internal memory, then, when described computer system free time or dormancy, again the operation information of buffer memory is written in the second hard disk, to save the operating resource of computer system, improves the operational efficiency of computer system.
Like this, through above-mentioned steps, each client operating system in computer system can be recorded in the second hard disk the relevant information of the write operation of the first hard disk.Original backup data in the second hard disk have been preserved the data of the first hard disk before certain time point, operation information in the second hard disk has been preserved the data situation on the first hard disk after above-mentioned time point, thereby has realized the full backup to the first hard disk.
From the above, can find out, because virtual machine manager can be tackled the write operation order of all operations system, the present embodiment does not rely on third party software, not only can be to the backup of being correlated with of certain specific operating system, and can back up the data of client operating systems all in computer system.And, because the backup operation of the present embodiment is the write operation order that is synchronized with operating system, thereby can realize fine-grained, lasting data backup.
After above-mentioned steps 14, if user wants the first hard disk to carry out data recovery, can in the restarting process of computer system, input the data of the first hard disk are recovered to order, indication wishes to return to which time point (being some release time).Also can the described very first time corresponding to all operations information of preserving in the second hard disk all be printed by described computer system, by user, therefrom select concrete some release time.When the first hard disk being carried out to data recovery, the present embodiment can also comprise the following steps after above-mentioned steps 14:
By above-mentioned steps 15, first recover the raw data in the first hard disk; By step 16～17, according to the first operation information, the data to the first hard disk at original backup time point and between putting described release time are recovered, thereby the data on the first hard disk are returned to the state of putting described release time again.
It is to be noted, in the present embodiment, be to take first, second hard disk to describe as example, the first hard disk and the second hard disk can be two physical hard disks independently in described computer system, the second hard disk can also be arranged on the independent hard disk outside described computer system, for example be arranged on a hard disk in home server network, or a hard disk of internet far-end.The present embodiment can also be applied under the environment that only has a physical hard disk, now, this part physical hard disk can be marked off at least two separate storage unit, all client operating systems are arranged in one of them storage unit, described original backup data and described operation information are all kept in another storage unit in this physical hard disk.
Method based on above-mentioned hard disc data backup protection, the present embodiment also correspondingly provides a kind of computer system, and as shown in Figure 2, this computer system comprises:
At least one client operating system;
The first storage unit;
The second storage unit;
