Description
Technical Field
The present invention relates to the field of data storage, and in particular, to a method and an apparatus for data transmission.
Background
The distributed data storage system stores data on different machines, thereby avoiding the bottleneck brought by single machine centralized storage. In the process of storing data in a distributed manner, part of data on one machine is generally transferred to another machine for data migration due to overload, limited storage space, and the like. In addition, in order to ensure the reliability of data, the same data is stored in a plurality of devices at the same time, and when a device in which one data is located fails, data recovery can be performed by using data in other devices.
Currently, migration and recovery of data in distributed data storage systems is done manually by operation and maintenance personnel using export dump tools and import load tools. For example, the operation and maintenance personnel export the data to be migrated or restored to a file on the machine a by using a dump tool, then transfer the file to the machine B, and import the file on the machine B by using a load tool to obtain the data to be migrated or restored.
However, the migration and recovery process of the data can be completed only by relying on manual assistance, and when data of different services or data of different storage formats are migrated or recovered, corresponding operations must be manually executed on a dump tool and a load tool, so that the operations are complicated, the efficiency is low, and the automation of operation and maintenance is difficult to realize.
