Abstract
The present invention relates to a kind of anti-error method deleting loss data of USB flash disk, described USB flash disk includes backup module, memory module, execution module, when memory module is write, perform module and replicate presently written data to backup module, in the case of occurring deleting by mistake, the recovery of data can be carried out by the data opening backup module, thus avoid USB flash disk to delete by mistake and cause loss of data.The inventive method is advanced, science; pass through the present invention; when memory module is write; perform module and replicate presently written data to backup module; thus when occurring deleting in the case of by mistake, the recovery of data can be carried out by the data opening backup module, thus avoid USB flash disk to delete by mistake and cause loss of data; thus improve safety, reach to protect the purpose of USB flash disk data.
Description
Technical field
The present invention relates to a kind of anti-error method deleting loss data of USB flash disk, belong to USB flash disk safety design technical field.
Background technology
USB flash disk, full name USB flash drive, it is that a kind of miniature high power capacity without phisical drive using USB interface moves
Storage product, is connected with computer by USB interface, it is achieved plug and play.Along with the universal of computer utility and storage device
The expanding day of capacity, the use of movable storage device is more and more extensive, the problem thus having caused storage equipment security.
Existing USB flash disk, once data are deleted by mistake, the most direct complete deletion, and the data of deletion are difficult to recover, thus the work to people
Bring the biggest inconvenience.
Summary of the invention
The purpose of the present invention is aiming at the drawback that above-mentioned prior art exists, it is provided that one can improve USB flash disk safety
USB flash disk anti-error delete lose data method.
The object of the present invention is achieved like this, and a kind of USB flash disk is anti-error deletes the method losing data, it is characterized in that: described USB flash disk
Including backup module, memory module, execution module, the memory capacity of described backup module is identical with the capacity of memory module；When
When memory module is write, perform module and replicate presently written data to backup module, copying data to backup
Before module, perform module and first obtain the size of presently written file, then obtain the remaining memory space of backup module, when standby
Presently written file more than or equal to the size of presently written file, is then directly copied to by part remaining memory space of module
Backup module, when the remaining memory space of backup module is less than the size of presently written file, performs module and judges according to the time
Delete time file earlier in backup module, until the remaining memory space of backup module is more than or equal to presently written
The size of file, execution module retells presently written file and is copied to backup module；In the case of occurring deleting by mistake, Ke Yitong
Cross and open the data of backup module and carry out the recovery of data, thus avoid USB flash disk to delete by mistake and cause loss of data.
It is additionally provided with regular removing module, the time arranged according to regular removing module in described backup module, mould will be backed up
The data of the backup in block carry out emptying process.
The time that described regular removing module sets was as 1 week.
Described USB flash disk also includes display module, and display module is in real time by the residue storage area in backup module and storage mould
The residue storage area of block.
Described display module is display.
The inventive method is advanced, science, by the present invention, when writing memory module, performs module duplication and works as
The data of front write are to backup module, thus in the case of occurring deleting, can be carried out by the data opening backup module by mistake
The recovery of data, thus avoid USB flash disk to delete by mistake and cause loss of data, thus improve safety, reach to protect USB flash disk data
Purpose.
Accompanying drawing explanation
Fig. 1 is the workflow diagram of the present invention.
Detailed description of the invention
A kind of USB flash disk is anti-error deletes the method losing data, including backup module, memory module, execution module, described backup mould
The memory capacity of block is identical with the capacity of memory module；When memory module is write, perform module and replicate presently written
Data to backup module, before copying data to backup module, perform module and first obtain the size of presently written file,
Then the remaining memory space of backup module is obtained, when the remaining memory space of backup module is more than or equal to presently written file
Size, then directly presently written file is copied to backup module, when the remaining memory space of backup module is less than current
The size of write file, performs module and judges to delete time file earlier in backup module according to the time, until backup
The remaining memory space of module, more than or equal to the size of presently written file, performs module and retells presently written file duplication
To backup module；When occurring deleting in the case of by mistake, the recovery of data can be carried out by the data opening backup module, thus keep away
Exempt from USB flash disk to delete by mistake and cause loss of data.In the present invention, in backup module, it is additionally provided with regular removing module, according to periodically
The time that removing module is arranged, carry out emptying process by the data of the backup in backup module.Periodically removing module set time
Between be 1 week.USB flash disk also includes display module, and display module is in real time by the residue storage area in backup module and memory module
Residue storage area.Display module is display.
Claims (5)
1. USB flash disk is anti-error deletes the method losing data, it is characterized in that: described USB flash disk includes backup module, memory module, execution
Module, the memory capacity of described backup module is identical with the capacity of memory module；When memory module is write, perform mould
Block replicates presently written data to backup module, before copying data to backup module, performs module and first obtains currently
Write file size, then obtain the remaining memory space of backup module, when the remaining memory space of backup module more than or
Equal to the size of presently written file, then directly presently written file is copied to backup module, when backup module is remaining
Memory space, less than the size of presently written file, performs module and judges that in deletion backup module, the time is earlier according to the time
File, until the remaining memory space of backup module is more than or equal to the size of presently written file, performs module and retell and work as
The file of front write is copied to backup module；In the case of occurring deleting, can be carried out by the data opening backup module by mistake
The recovery of data, thus avoid USB flash disk to delete by mistake and cause loss of data.
