Methods and devices for backup and recovery of records in mobile terminal

Abstract

The invention provides a method and a device for backing records up in a mobile terminal. The method comprises the following steps of: according to a received record backup instruction, comparing the records in a to-be-backed-up record set of the mobile terminal with those in a backup record set one by one; judging whether the records are the same according to record comparison identifiers; and if the records identical with those in the to-be-backed-up record set exist in the backup record set, backing up the records in the record set with relatively higher priority according to preset record priorities, and performing the backup on the records, different from those in the backup record set, in the to-be-backed-up record set. The invention also provides the method and the device for recovering the records in the mobile terminal. Through the methods and the devices of the invention, repeated records can be merged and processed, the different records can be backed up or recovered, and the identical records in the record set with the relatively higher priority are backed up or recovered, so the utilization rate of a memory space and record backup efficiency are improved and the integrity of the recovered records is improved.

Description

technical field [0001] The invention relates to record backup and recovery technology, in particular to a method and device for record backup in a mobile terminal, and a recovery method and device. Background technique [0002] With the continuous improvement of the intelligence of mobile terminals, the configuration of mobile terminal systems and application software is becoming more and more complex, and more and more user data are stored in mobile terminals. The above data is very important to mobile terminal users. The demand for terminal data backup and recovery is increasingly strong. The user data of the mobile terminal includes telephone data, picture data, video data, audio data, SMS data, etc., and the above-mentioned data in various formats are stored in the form of records on the mobile terminal, and each record contains the record The content, modification time, and identification information of the record, all of which are included in the record when the mobil...

AI Technical Summary

Problems solved by technology

The existing mobile terminals only temporarily store the records of the mobile terminal. Since the storage space of the mobile terminal is very limited, when a large number of records are temporarily stored in the mobile terminal, the running speed of the mobile terminal may be affected, and the user's misoperation Or the failure of the mobile terminal may lead to the loss of the temporary storage records of the mobile terminal, which will bring certain losses to the user

In the existing mobile terminal record backup method, the mobile terminal stores the records that the user needs to back up on the medium used for backup. The medium used for backup can be a memory card installed in the mobile terminal or a memory card installed in the mobile terminal. Other storage media; because there may be duplicate records in the records that users need to back up each time, this may take up a lot of storage space, cause waste of storage space, and affect the efficiency of mobile terminal record backup; due to the possible existence of the above backup process Duplicate records occupy a large amount of storage space, and may also cause the records that users need to back up to be unable to be stored

[0003] When data is lost due to user misoperation or mobile terminal failure, the backup record set stored on the medium used for backup can replace the record temporarily stored in the mobile terminal; Some important records in the records may be deleted, and some duplicate records in the backup record set are stored on the mobile terminal, which may cause the loss of important records and the storage of duplicate data. The records recovered by the mobile terminal are incomplete, and the restored records Records have duplicate issues

[0004] To sum up, the existing mobile terminal record backup method has the problems of low record backup efficiency and low storage space utilization, and the existing mobile terminal record recovery method has incomplete recovered records and duplicated records. question
