The present invention mainly relates to the technical field of Internet. Disclosed are a data transmission method, device, and server, which mainly aim to prevent data loss in a data transmission process. The method comprises: receiving, at a geographical position at which a first server is located, data that is from the first server and is to be sent to a second server, the second server and the first server being located at different geographical positions; storing the data in a preset queue; acquiring the data from the queue, and sending the data to the second server; determining whether the data is successfully sent to the second server; and when the data fails to be sent, reacquiring the data from the queue and sending the data. According to the technical solution of the present invention, the occurrence of data loss can be effectively prevented.
