Abstract

The invention relates to a built-in database based high-efficient data deleting and restoring method, which sequentially includes a packet generating step, a packet storing step, a packet damage detecting and converting step, a packet deletion detecting step, a packet relevance comparing step and a packet dynamic monitoring and restoring step. Accordingly, the technical problem that data which are accidentally deleted and lost possibly cannot be restored or are poor in restoring effect in the prior art is solved, the function of instantly thoroughly restoring deleted data caused by misoperation of users is realized and can be kept for a long time by remote support of a server, and risk in data loss of operation of a built-in operation system for users is effectively reduced and convenience is provided for the users.

Description

technical field [0001] The invention belongs to the technical field of computer data processing, in particular to an efficient data deletion and recovery method based on an embedded database. Background technique [0002] With the continuous development of science and technology, people's requirements for computer data deletion and recovery continue to increase. Among them, the extended file allocation table is a file system released by Microsoft in 2006 that can replace Fat16 and Fat32. [0003] A hard disk typically includes a certain number of user data areas, preceded by synchronization information including a preamble and a data sync pattern. The preamble is used to synchronize phase and frequency during asynchronous reads, while the data sync pattern is used to define the starting point of a series of user data. In operation, the circuit searches for a data synchronization pattern and processes a series of sequentially received data samples obtained at locations assoc...
