Abstract
The invention relates to a backup method for data in a hard disk. The backup method comprises the steps that the hard disk is provided with a main storage area, a first backup area and a second backup area; the main storage area is checked before data storage, wherein if the main storage area is in a good condition, data is stored in the main storage area, and backup is carried out in the backup areas; if the main storage area is partially damaged, the remaining capacity of the undamaged part is confirmed, the data is stored in the undamaged part in the main storage area if the remaining capacity is larger than the capacity of the data to be stored, and meanwhile backup is carried out in the backup areas; if the remaining capacity is smaller than the capacity of the data to be stored, the data is stored into the first backup area and the second backup area; if the main storage area is completely damaged, the data is stored into the first backup area and the second backup area. According to the scheme, the consistency and effectiveness of the data in all the areas are ensured by setting the double backup areas in the single hard disk and combining multiple times of regular self-checking, so that the anti-losing capability of data is improved, and the safety, stability and reliability of the data in the hard disk are improved.

Technical field
The present invention relates to a kind of method for hard disc data is backed up.
Background technology
Along with the arriving of big data age, the rapid expansion of user group, user to the stability of data,
The requirement of reliability and safety is more and more higher.At present, conventional hard disk includes that mechanical hard disk and solid-state are hard
Dish, mechanical hard disk is owing to easily being affected by temperature, vibration and read-write error occurred, and solid state hard disc is certainly
The restriction of erasable number of times and bad block rate that body is intrinsic also result in read-write error.Although hard disk self has error correction
Function, but it can only correct the mistake less wrong data of figure place by self error correction algorithm, and therefore it entangles
Wrong ability is extremely limited.
In the prior art, there are some relatively new methods to may be used for protection and Backup Data, prevent
It is lost because of hard disk corruptions, but these method complex operations, the requirement to hard disk self is high, and protection
Relatively costly.
Summary of the invention
In place of the deficiencies in the prior art, it is an object of the invention to provide a kind of for hard disc data
The method carrying out backing up, it can give data multiple protective, provide safe and stable, reliable for data
Storage condition.
Technical scheme is summarized as follows:
A kind of method for hard disc data is backed up, comprising:
Single hard disk is carried out subregion, is respectively set as hosting district, the first backup area and the second backup area；
Before storage data, check hosting district:
If it is intact to host district, then store data in main memory district, and the most standby at the first backup area and second
Part carries out automated back-up in district；
If hosting district's partial destruction, then recording the physical address of broken parts, confirming the surplus of non-broken parts
Covolume amount, if the residual capacity of non-broken parts is more than treating deposit data capacity, then stores data in main memory
Unspoiled part in district, carries out automated back-up in the first backup area and the second backup area simultaneously；If not
The residual capacity of broken parts less than treating deposit data capacity, then stores data in the first backup area, with
Time in the second backup area, carry out automated back-up；
If hosting district all to damage, then storing data in the first backup area, entering at the second backup area simultaneously
Row automated back-up.
Preferably, the described method being used for hard disc data is backed up, wherein, also include:
Set first proof cycle and detect hosting district, if finding to host in district has data to occur
Damage, then format and host district, and copy to the data in the first backup area host in district.
Preferably, the described method being used for hard disc data is backed up, wherein, also include:
Set second proof cycle the first backup area is detected, if finding the first backup area has
Data are damaged, then format the first backup area, and the data in the second backup area are copied to first
In backup area.
Preferably, the described method being used for hard disc data is backed up, wherein, also include:
Set the 3rd proof cycle main memory district and the first backup area are compared, and will not have each other
Data carry out respectively supplementing backup, to ensure to host district and the data consistent of the first backup area.
Preferably, the described method being used for hard disc data is backed up, wherein, also include:
Set the 4th proof cycle the first backup area and the second backup area are compared, and will each other
The data not having carry out supplementing backup, to ensure the first backup area and the data consistent of the second backup area respectively.
Preferably, the described method being used for hard disc data is backed up, wherein, also include:
Set the 5th proof cycle main memory district, the first backup area and the second backup area to be compared simultaneously
Right, and by the data not having each other respectively carry out supplement backup, with ensure host district, the first backup area and
The data consistent of the second backup area.
Preferably, the described method being used for hard disc data is backed up, wherein, also include:
Check the second backup area, when the second backup area damages, stop hosting district and the number of the first backup area
According to import feature, retain data export function.
The invention has the beneficial effects as follows: this case is by arranging dual backup region in single hard disk, and ties
Close regular self-inspection repeatedly and guarantee data concordance in each area and effectiveness, thus improve
The anti-lost ability of data, adds data safety, stability and reliability in a hard disk.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, to make those skilled in the art join
Book word can be implemented according to this as directed.
This case propose an embodiment for the method that hard disc data is backed up, comprising:
