Method and computation node for processing application data

摘要

The present invention provides a method and a computation node for processing application data. The method includes: starting, by an operating system, a service process; establishing, by the operating system, a socket connection between the service process and backup software, where the service process has a root operation right, and the service process and the backup software have the same user identifier; sending, by the backup software through the socket, a processing request for application data; receiving, by the service process through the socket, the processing request for application data, where the processing request is sent by the backup software, sending the processing request for application data to corresponding application software, receiving application data returned by the corresponding application software, and sending the returned application data to the backup software through the socket.

1. A method for processing application data, applied to a single computation node, comprising:
creating, by an operating system in the single computation node, in the single computation node a service process with a root operation right and a user identifier (uid), wherein the uid is set as exactly the same as the uid of a backup software in the single computation node; establishing, by the operating system, a socket connection between a service process and the backup software; receiving, by the service process through the socket connection, a processing request for application data from the backup software; sending, by the service process, the processing request for application data to a corresponding application software in the single computation node; receiving, by the service process, application data returned by the corresponding application software, wherein the application data comprises application data returned in response to the processing request; and sending, by the service process through the socket connection, the returned application data to the backup software.
