Abstract
The utility model discloses a backup flash disk. The existing flash disk is easily in failure after being used for a long time, or data in the flash disk infected by virus is easy to lose, the lost data is difficult to recover, thereby bringing about great loss to the user. The backup flash disk comprises a universal serial bus (USB) interface and a storage chip, and is characterized by also comprising a data synchronizing device, a backup storage chip and a backup USB interface, wherein the USB interface is connected with the storage chip, the storage chip is connected with the data synchronizing device, the data synchronizing device is connected with the backup storage chip, and the backup storage chip is connected with the backup USB interface. The data in the storage chip and the backup storage chip can be synchronously updated through the data synchronizing device; and when the storage chip is malfunctioned or the damaged data cannot be read, the same data in the backup storage chip and the storage chip can be read through the backup USB interface, and the loss of the data in the flash disk can be avoided.
Description
Technical field
The utility model relates to the data storage device technical field, specifically a kind of flash disk that backs up.
Background technology
Flash disk, full name USB flash memory driver, English name " USB flash disk " is called for short USB flash disk, and it is a kind of miniature high power capacity mobile storage product that need not phisical drive that uses USB interface, is connected with computer by USB interface, realizes plug and play.After USB flash disk is connected to the USB interface of computer, the data of USB flash disk can exchange with computer, be used for storage picture, data, image, realize portable mobile storage, improved office efficiency greatly, make the human lives more convenient, storing important data in the flash disk mostly, existing flash disk breaks down after having used of a specified duration easily, perhaps the data in the virus back is easy to lose in the flash disk, the data of losing is difficult to recover, just caused very big loss to the user, existing flash disk does not have to realize the function of data backup yet.
Therefore, design and can back up in realtime to the data in the flash disk for the deficiency that overcomes above-mentioned technology, after flash disk breaks down, a kind of flash disk that backs up that data still exists, inventor's problem to be solved just.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of flash disk that backs up, and it is simple in structure, and is easy to use, can back up in realtime to the data in the flash disk, and after flash disk broke down, data still existed.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of flash disk that backs up, comprise USB interface and storage chip, it is characterized in that: it also comprises data synchronization unit, back-up storage chip and backup USB interface, described USB interface is connected with storage chip, storage chip is connected with data synchronization unit, described data synchronization unit is connected with the back-up storage chip, and described back-up storage chip is connected with the backup USB interface.
The beneficial effects of the utility model are: by traditional flash disk is improved, the chip of two data storages is set in flash disk, and by data synchronization unit the data in storage chip and the back-up storage chip is upgraded synchronously, when storage chip breaks down or corrupt data when can not read, can by the backup USB interface read in the back-up storage chip with storage chip in identical data, avoid losing of data in the flash disk, accomplished the backup at any time of data.
Description of drawings
Fig. 1 is principle schematic of the present utility model.
Description of reference numerals: 1-USB interface; The 2-storage chip; The 3-data synchronization unit; 4-back-up storage chip; 5-backs up USB interface.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values drop on application appended claims institute restricted portion equally.
Fig. 1 can back up the principle schematic of flash disk for the utility model, it is made up of usb 1, storage chip 2, data synchronization unit 3, back-up storage chip 4 and backup USB interface 5, described usb 1 is connected with storage chip 2, storage chip 2 is connected with data synchronization unit 3, data synchronization unit 3 is connected with back-up storage chip 4, and back-up storage chip 4 is connected with backup USB interface 5.
The utility model in use, upgrade synchronously by the data in 3 pairs of storage chips 2 of data synchronization unit and the back-up storage chip 4, when storage chip 2 breaks down or corrupt data when can not read, can by backup USB interface 5 read in the back-up storage chip 4 with storage chip 2 in identical data, so just avoid losing of data in the flash disk, accomplished the backup at any time of data.
