Problems solved by technology

However, the calculation of the SHA-1 encryption algorithm is complex and consumes a lot of CPU
At the same time, because the data segment is too small, when the user backs up a large amount of data, the fingerprint space consumed is also large, and there are still certain scalability problems

[0083] The running support environment of the backup service system application is:

[0084] 1. Hardware environment and supporting environment

[0085] The backup client requires the host to have a memory of 512M or above and a network throughput of 10Mbps or above.

[0086] The scheduling server requires the host to have a memory of 2GB or above and a network throughput of 1000Mbps or above.

[0087] The storage server requires the host to have 4GB or more memory and TB-level external storage capacity, and a network throughput capacity of 1000Mbps or more.

[0088] The scheduling server and the host where the storage server software are located have GB-level network exchange capabilities, and the client and server software hosts have network connectivity capabilities. The environment where the server host is located is required to have redundant power supply guarantee, redundant communication link guarantee, temperature control system, fire protection system and other basic ...

Abstract

The invention discloses a data organization method for a backup service software storage server side for improving data organization and data management efficiency of the storage server side. The method comprises the following steps: (1) initializing a storage space of the storage server as a metadata area (comprising main record, index head and data index) and a data area; (2) receiving and judging a user operating command, sequentially performing a backup operation, recovering the operation and turning to step (4), and canceling the operation and turning to step (5); (3) processing a user backup operation, backing up user data to the data area of the storage server, meanwhile avoiding repeated data backup by using repeated data canceling technology, and turning to the step (2); (4) processing the recovery operation, positioning and searching a recovered data list specified by a user in the data area of the storage server, then transmitting the recovered data list to a user side, and turning to the step (2); and (5) processing the canceling operation, searching the canceled data specified by the user, introducing counting according to backup data blocks of the data in the data area of the storage server to perform corresponding processing, and turning to the step (2). The method improves the utilization rate and manageability of the storage server side and the expandability of the system, saves the network bandwidth, and improves the backup efficiency.

Description

technical field [0001] The invention belongs to computer data storage and backup methods, and in particular relates to a data organization method for backup services. The method realizes the deletion of block-level repeated data. Background technique [0002] With the rapid development of the information society, people's daily life and business operations of enterprises are surrounded by increasingly infiltrated information systems, and their dependence is increasing. Especially in industries such as finance, communication, transportation and insurance, once key data is lost or damaged, it will bring immeasurable losses to individuals and enterprises. [0003] The backup service mentioned here is essentially a backup and recovery software system that provides a certain disaster recovery function. It can provide individual and enterprise users with comprehensive data backup, recovery and related management tasks, and can customize various backup strategies according to their...
