Abstract

Provided are an online file migration method, device and system. The method includes: mounting a source device to a target device through a network file sharing protocol, the source device and the target device both being an NAS device; establishing on the target device a mirror file of a file on the source device, the mirror file being initially an empty file; migrating the data in the file on the source device to the target device through network transmission by way of the network file sharing protocol; and processing an access request of a user by the target device during data migration. The technical solution in the present invention can realize online file migration between two NAS devices and can be suitable for online file migration among NAS devices manufactured according to different standards or by different manufacturers.

Description

technical field [0001] The invention relates to data storage technology, in particular to a file online migration method, device and system. Background technique [0002] Network Attached Storage (NAS) equipment has been widely used as a network storage device. At the same time, with the development of information technology and the increase in the amount of information, NAS equipment is updated more and more frequently. When updating a NAS device, it is necessary to migrate the files on the source device to be updated to the target device. [0003] At present, when migrating files on the source device to the target device, it is usually necessary to stop the user services on the source device, then use a copy tool to copy the files on the source device to the target device, and finally enable the new device, which will cause User services are interrupted. Therefore, in order to ensure that user services are not interrupted, online migration of files is required. In the pr...
