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 present invention provides a method and device for background transmission of backup data, comprising: when obtaining a data backup command sent by a user, determining the data to be backed up in the target storage volume and the source storage volume; obtaining an integer selected by the user within the data transmission rate interval value, and perform data type conversion on the integer value, save the conversion value obtained after the data type conversion to the preset shift memory, and perform a shift operation in the shift memory to obtain the data representing the background transmission per second The shift value of the number of blocks; according to the size of the data block and the shift value, the transmission rate of the background transmission data is determined. Applying the present invention, the transmission rate of the background transmission data can be changed by using the shift memory, and the user can use the shift memory to control the transmission rate of the background with index changes, and can flexibly control the transmission rate of the background transmission data, which improves the transmission of the background transmission number The flexibility of the rate, and the improvement of the work efficiency of the system applying the present invention.

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...
