Abstract

The invention discloses a data backup method and system, a data recovery method and system and a mobile terminal, and the method comprises the steps: carrying out the combination and compression of source data through employing a compression algorithm, generating a compressed first source data file, carrying out the summary calculation, and obtaining first summary data; performing encryption calculation on the first abstract data to obtain first encrypted data; packaging the attribute information of the source data and the first encrypted data to obtain first verification information data; andwriting the first verification information data into the compressed first source data file to generate a backup file, and finishing data backup. According to the method, the compressed backup file isabstracted and encrypted by adopting a compression algorithm and a digital abstract and encryption technology, and verification information and the compressed backup file are combined together, so that the backup file has good safety, is tamper-proof and forgery-proof, is convenient to manage, and guarantees the safety and integrity of recovered system data.

Description

technical field [0001] The present invention relates to the technical field of data management, and more specifically, to a data backup method and system, a data recovery method and system, and a mobile terminal. Background technique [0002] Computer software systems may cause data loss due to factors such as operational errors, system failures, or accidental reasons. Data backup and recovery are indispensable. The security of backup data is particularly important, especially when uploading and downloading data through the network environment. It should be considered that the backup data may be incompletely lost or even maliciously modified by someone, resulting in the restored system not working properly or the data being inconsistent with before restoration. [0003] Therefore, there is a need for a method that can safely and completely manage data. Contents of the invention [0004] The invention proposes a data backup method and system, a data recovery method and sys...
