Embodiment Construction

[0044] The present invention is described in detail below in conjunction with accompanying drawing.

[0045] According to the multi-level storage and recovery method of log files in the cloud environment of the present invention, three levels of log storage and recovery schemes are allocated according to user levels and configuration requirements, namely fast storage and recovery, general storage and recovery, and complete storage and recovery.

[0046] Such as figure 1 , 2 As shown, the specific implementation of fast storage and recovery is as follows: when the log recovery method of the present invention is enabled, call figure 1 In the log level management module, when the user selects fast storage and recovery, the system first encapsulates the user's basic operations into a string in the form of "login user ID + log time + operation type + specific operation + operation object + remarks"; and then calls figure 1The general encryption and decryption module of the genera...

Abstract

The invention discloses a multi-level storage and recovery method and system of a journal file in a cloud environment, and belongs to the field of communication applications of computer networks. The multi-level storage and recovery method of the journal file in the cloud environment comprises three levels, namely rapid storage and recovery, ordinary storage and recovery and complete storage and recovery, and a journal level management module determines the storage and recovery level of the journal file according to user levels and configuration requirements and executes corresponding steps. The multi-level storage and recovery system of the journal file in the cloud environment comprises the journal level management module, a general encryption / decryption module, a stored journal management module, a JMS message management module and a database management module which are contained in the same Gatekeeper. The multi-level storage and recovery method and system of the journal file in the cloud environment make full use the characteristics of an internal storage, a JMS message and a database, realize various storage and recovery modes of the journal file in the cloud environment, such as the rapid storage and recovery mode, the ordinary storage and recovery mode and the complete storage and recovery mode, avoid space waste, reduce data redundancy, further improve the storage and recovery efficiency, and realize classified recovery and ranking of journals.

Description

technical field [0001] The invention relates to a method and system for multi-level storage and restoration of log files in a cloud environment, belonging to the field of computer network communication applications. Background technique [0002] Cloud computing is a computing model that provides dynamically scalable virtualized resources in the form of services through the Internet. At present, cloud computing is more and more widely used, and the system is becoming larger and larger. The backup, recovery, and restoration of the system are often used. However, log files are an important basis for recovery and restoration, but they are easy to be lost. attack or tampering. [0003] At present, most of the log file protection technologies in the cloud environment adopt the method of copying multiple log files and storing them in multiple places. The disadvantages: (1), resulting in a waste of storage space, especially for large files , the waste increases geometrically; (2) ...
