Embodiment Construction

[0069] In view of the deficiencies in the existing technology, it is necessary to propose a method to back up data to scattered storage devices in the network through this technology in a low-bandwidth network environment, so that the replication process can use network concurrency to increase bandwidth, thereby improving the overall performance of replication .

[0070] Based on the above purpose, the present invention proposes a data backup method, which is applied to a system including multiple backup servers, data servers, and management servers. The management server is connected to the data server and multiple backup servers, and the The data is allocated to the corresponding backup server for backup, and the management server establishes a data backup list to record the storage location information of the data in the data server in each backup server.

[0071] Such as Figure 5 As shown, it is a schematic flow chart of a data backup method proposed by the present inven...

Abstract

The invention discloses a method and equipment for database backup. Through the technical scheme of the invention, storage equipment in a low-bandwidth network environment can be used for data disaster recovery so that bandwidth is widened by using network concurrency in a copying process, the integrity of copy is promoted, data required to be usually used and modified are integrated onto the network storage equipment with good network status and the data not required to be usually used and modified are stored onto the network storage equipment with relatively poor network status. The method and the equipment guarantee the service performance after a disaster recovery center substitutes when a production center breaks down while the copy performance is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a data backup method and device. Background technique [0002] Storage replication technology mainly includes disk array replication technology, host volume replication technology and some file replication technologies. [0003] The technical core of the storage replication solution is to use the disk array-to-disk data block replication technology of the storage array itself to realize the remote copy of the production data, so as to realize the disaster protection of the production data. When a disaster occurs in the main data center, the data in the disaster recovery center can be used to establish an operational support environment in the disaster recovery center to provide IT support for business continuation. At the same time, the data in the disaster recovery center can also be used to restore the business system of the main data center, so that the business operat...
