Data backup method, device and equipment

Abstract

The invention provides a data backup method, a device and equipment. A programmable chip is integrated on a mainboard, when data is stored, the programmable chip analyzes a data packet to be backed up received from a network card to obtain a TCP data packet only containing data flow in the data packet to be backed up, after the TCP data packet is stored in a target cache data space, a physical address for writing the TCP data packet into the disk array is obtained from a CPU, and finally, the TCP data packet is stored in a specified position of the disk array corresponding to the physical address. Therefore, by applying the technical scheme provided by the embodiment of the invention, the overhead of the CPU can be greatly reduced, so that the CPU does not cause insufficient processing performance due to storage of the TCP data packet, and further the backup performance is not influenced.

Description

technical field [0001] The present application relates to data storage technology, in particular to a data backup method, device and equipment. Background technique [0002] Network backup refers to the centralized management of data backup in the entire network through data backup management software combined with corresponding hardware and storage devices in a network environment, so as to realize automatic backup, file archiving, data hierarchical storage, and disaster recovery. Install the backup client software on the server that needs to perform data backup management in the network, and centrally back up the data to the storage device through the network. [0003] At present, in the existing technology, during the execution of the backup task, two types of data packets of the control flow type and the data flow type are usually transmitted to the backup server. All the data is sent to the backup software in the user space by the CPU (central processing unit) for proc...

Problems solved by technology

And all the data is sent to the backup software in the user space by the CPU (central processing unit, central processing unit) for processing, and then stored in the disk array, but the CPU resources will be consumed all the time when the data is copied

However, in practical applications, the data whose type is control flow is generally small and will not have a significant impact on the CPU, but the data whose type is data flow is different, it contains all the data that needs to be backed up, usually hundreds of MB to Hundreds of GB, which will cause a huge CPU overhead, which will affect the backup performance due to insufficient CPU processing performance
