Embodiment Construction

[0011] A method for U disk to prevent accidental deletion of lost data, including a backup module, a storage module, and an execution module, the storage capacity of the backup module is the same as that of the storage module; when the storage module is written, the execution module copies the current write The input data is sent to the backup module. Before copying the data to the backup module, the execution module first obtains the size of the currently written file, and then obtains the remaining storage space of the backup module. When the remaining storage space of the backup module is greater than or equal to the currently written file size, then directly copy the currently written file to the backup module. When the remaining storage space of the backup module is smaller than the size of the currently written file, the execution module will delete the earlier files in the backup module according to the time judgment until the backup module The remaining storage space is...

Abstract

The invention relates to a Method for preventing USB data misdeletion and loss. A USB comprises a backup module, a memory module and an execution module, when write-in is performed on the memory module, the execution module copies the current write-in data to the backup module, data in the backup module can be opened for data recovery under a misdeletion condition, and data loss caused by misdeletion from USB is avoided. The method is advanced and scientific, when write-in is performed on the memory module, the execution module copies the current write-in data to the backup module, the data in the backup module can be opened for data recovery under the misdeletion condition, and data loss caused by misdeletion from the USB is avoided, so that the security is improved, and the data in the USB is protected.

Description

technical field [0001] The invention relates to a method for preventing accidental deletion and lost data of a U disk, and belongs to the technical field of U disk safety design. Background technique [0002] U-disk, the full name of USB flash drive, is a miniature high-capacity mobile storage product that uses a USB interface without a physical drive. It is connected to a computer through a USB interface to achieve plug-and-play. With the popularization of computer applications and the increasing capacity of storage devices, the use of mobile storage devices is becoming more and more extensive, which has caused the problem of storage device security. Existing U-disk, once data is mistakenly deleted, generally all directly delete completely, and deleted data is difficult to restore, thereby brings very big inconvenience to people's work. Contents of the invention [0003] The object of the present invention is to provide a method for preventing accidental deletion and los...
