Problems solved by technology

[0003] The inventor found that the existing backup data transmission method transmits the backup data according to a fixed transmission rate. When the backup data transmitted in the source storage volume is large, the data is transmitted according to the fixed transmission rate. It is very likely to spend more time, resulting in low system efficiency; when the backup data transmitted in the source storage volume is very small, it is likely to cause a waste of transmission resources if the transmission is carried out at a fixed transmission rate; the data of the prior art The flexibility of the transmission method is extremely poor, resulting in a decrease in the work efficiency of the entire system

Abstract

The invention provides a background transmission method and device for backup data. The background transmission method comprises the steps: determining to-be-backed-up data in a target storage volumeand a source storage volume when a data backup instruction transmitted by a user is obtained; obtaining an integer value selected by a user in the data transmission rate interval, performing data typeconversion on the integer value, storing a conversion value obtained after the data type conversion into a preset shift memory, and executing a shift operation in the shift memory to obtain a shift value representing the number of data blocks transmitted per second in a background; and determining the transmission rate of background transmission data according to the size of the data block and the shift value. Application of invention, the shift memory can be used for changing the transmission rate of background transmission data, and a user can use the shift memory to control the backgroundtransmission rate with the index changed, and the transmission rate of the background transmission data can be flexibly controlled, and the flexibility of the transmission rate of the background transmission data is improved, and the working efficiency of the system applying the background transmission method is improved.

Description

technical field [0001] The invention relates to the technical field of data backup, in particular to a background transmission method and device for backup data. Background technique [0002] With the development of big data, reasonably backing up and storing data for disaster recovery has become a hot research topic for many researchers at the forefront of science and technology. There are many ways to backup and store data, such as snapshot backup, clone backup, etc.; when performing data backup, in most cases, the backup data of the source storage volume in the host is synchronized to the preset target storage volume through the background. A certain amount of bandwidth is required to synchronize the data to be backed up to the target storage volume. [0003] The inventor found that the existing backup data transmission method transmits the backup data according to a fixed transmission rate. When the backup data transmitted in the source storage volume is large, the data...
