Embodiment Construction

[0041] A management method for centralized storage of backup data provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] figure 1 A multi-user backup data organization table supporting deduplication backup according to an embodiment of the present invention is shown. like figure 1 As shown, the multi-user backup data organization table includes a user table, a task table, a backup point index table, a data block index table and a data warehouse. Among them, the user table stores information such as the user name and password of the end user for data backup; the task table records information such as the name of the backup task created by the end user, backup data, backup plan, backup options, etc., and saves the tasks and user tables. The mapping relationship between end users; the backup point index table records information such as the data object name, object attribute, and digit...

Abstract

The invention provides a multi-user backup data organization chart and a backup data centralized storage management method based on same; the method comprises the following steps: receiving data object description information of the backup data, backuping the data block corresponded by digital fingerprints in the data object description information which have different digital fingerprints with those of the multi-user backup data organization chart, storing the index information corresponded by the data block and the data object description information in the multi-user backup data organization chart in corresponding format and increasing the reference counts of the data block. The multi-user backup data organization chart comprises a user table, a task table, a backup point index table, a data block index table and a data warehouse. The invention can eliminate the repeated contents in each backup data of users in the backup stage, saves the transmission bandwidth and the cost of storage space and effectively reduces the occupied storage space of repeated data.

Description

technical field [0001] The present invention relates to the technical field of information security, and more specifically, the present invention relates to a management method for centralized storage of backup data. Background technique [0002] With the continuous development of computer technology and the continuous improvement of informatization, people's dependence on information is getting higher and higher. The highly centralized storage of information in the IT environment greatly improves the automation of information and data management, improves operational efficiency, and reduces costs. But at the same time, the risk is also increasing, so the data loss caused by the disaster may lead to huge losses. [0003] In order to avoid the adverse effects of disasters, it is necessary to establish a disaster recovery system to protect the key data of the production system. The decentralized construction of the disaster recovery system has greatly increased the construct...
