Abstract

The invention discloses a data backup method and a server. The data backup method is applied to the server. The server is provided with a batch checking interface and a portable operation system interface, and adopts network data management protocols. The data backup method comprises the following steps: receiving a backup instruction for backing up a data set; calling the batch checking interface to transmit a first checking instruction for checking attribute information of data in the data set to a file system, wherein the first checking instruction is used for instructing the file system to transmit all types of attribute information of the data in the data set to the server through the batch checking interface at one time; receiving all types of the attribute information transmitted from the file system; transmitting a storage instruction of all types of the attribute information to a backup server, wherein the storage instruction is used for instructing the backup server to back up the data of the data set according to all types of the attribute information. By adopting the data backup method and the server disclosed by the embodiment of the invention, the data backup efficiency can be improved.

Description

technical field

[0001] The invention relates to the technical field of the Internet, in particular to a data backup method and server. Background technique

[0002] Network Data Management Protocol (Network Data Management Protocol, NDMP) is an open protocol based on enterprise-level data management, which defines a network-based protocol and mechanism for controlling backup, recovery, and storage between primary and secondary storage. data transmission. At present, when using the NDMP server for data backup, the NDMP server needs to query the attribute information of the required backup data from the file system through the Portable Operating System Interface (POSIX), and then send the attribute information to the backup server . However, since POSIX can only query one type of attribute information of data each time, multiple queries are required to find all types of attribute information of the required backup data, thereby reducing the efficiency of data backup.
