Embodiment Construction

[0027] Embodiments of the present invention provide a data migration method and device, a network-attached storage device, and a storage medium, which can be applied to scenarios where data is migrated between network-attached storage devices. The multiple network attached storage devices may be heterogeneous devices, that is, the multiple network attached storage devices may be network attached storage devices of different manufacturers with different structures and different standards. figure 1 It is a schematic diagram of an application scenario of data migration in an embodiment of the present invention. Data can be migrated as files across multiple NAS devices. like figure 1As shown, files can be migrated between NAS A, NAS B, and NAS C. In the embodiment of the present invention, during the data migration process, the client can still access files. That is to say, during the data migration process, the client can still continue the task. Data migration will not cause...

Abstract

The invention provides a data migration method and device, a network attached storage device and a storage medium, and relates to the technical field of communication. The data migration method comprises: in the process that a source network attached storage device migrates data to a target network attached storage device, the target network attached storage device receives a data access request sent by a client; the target network attached storage device determining a to-be-accessed file root directory according to the to-be-accessed file path; determining that the to-be-accessed file is stored in a source network attached storage device according to the to-be-accessed file root directory, wherein the target network attached storage device stores a corresponding relationship between the root directory and the source network attached storage device; and the target network attached storage device forwarding the data access request to the source network attached storage device, receivesthe to-be-accessed file sent by the source network attached storage device, and sends the to-be-accessed file to the client. By means of the technical scheme, on-line data migration can be achieved under the condition that the data access service is not interrupted.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data migration method, device, network attached storage device and storage medium. Background technique [0002] Network Attached Storage (Network Attached Storage) equipment is a dedicated data storage server, including storage devices and embedded system software. Because network-attached storage devices can centrally manage data, release bandwidth, and improve network performance, network-attached storage devices are more and more widely used in networks. [0003] In the NAS heterogeneous operating environment, data sometimes needs to be migrated among different NAS devices. At this stage, it is necessary to deploy a third-party migration server. Use migration tools such as robocopy or rsync on the third-party migration server to migrate the data in a certain network-attached storage device to the third-party migration server, and then transfer the data to th...
