AI Technical Summary

Technical Problem

When switching user devices, existing technologies suffer from low data transfer efficiency during data migration, especially when migrating a large number of duplicate files, resulting in extremely low migration rates.

Method used

By determining M alternative transmission channels under certain conditions, transmission tests are conducted based on the test file according to the target dimension. File transmission security and corruption are selected for screening to determine the target transmission channel. Data migration is then performed between the target transmission channels, and the content to be migrated is deduplicated.

Benefits of technology

It improves data transmission efficiency, reduces the probability of data retransmission, increases migration speed, and solves the problem of low data transmission efficiency.

Abstract

The application discloses a data migration method, and particularly relates to the field of Internet, which comprises the following steps: determining M candidate transmission channels for data migration when the condition of data migration between a first device and a second device is met; M is an integer greater than 1; performing transmission test on the M candidate transmission channels according to a target dimension based on a test file to obtain a test result; the target dimension comprises at least one of a file transmission security dimension and a file transmission damage dimension; determining a target transmission channel from the M candidate transmission channels according to the test result; and performing data migration between the first device and the second device based on the target transmission channel.
