Method, device and system for transmitting data

Abstract

The embodiment of the invention discloses a method, a device and a system for transmitting data. According to one specific embodiment, the system comprises a mobile storage server, wherein the mobile storage server is configured to respond to a received copying task which is input by a user and comprises a source data path, execute the copying task in parallel through at least one USB device and / or an NFS file system and perform streaming encryption on copied data, after copying is completed, the mobile storage server is transported to a machine room where the cloud controller is located; a cloud controller which is configured to decrypt the data in the mobile storage server to obtain source data, generate a check code according to the source data, and upload the source data with the check code to the cloud storage server through the intranet; and a cloud storage server which is configured to perform data consistency verification on the received source data, and if the verification fails, the cloud storage server sends a retransmission instruction to the cloud controller. According to the embodiment, the bandwidth cost is reduced, the transmission speed is increased, and the data security is guaranteed.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to methods, devices and systems for transmitting data. Background technique [0002] With the development of the Internet era, the scale of enterprise data continues to increase by orders of magnitude, from the original GB level to TB, PB or even EB level. The explosive growth of data volume has brought data storage pressure to enterprises. At the same time, the popularization of cloud computing technology has made cloud-based data storage a mainstream choice. Cloud storage can provide enterprises with safe, reliable, massively scalable, and data disaster-tolerant storage services, reducing costs. [0003] The transmission of PB or even EB level data from the local data center to the cloud storage system is a costly and time-consuming project. Therefore, the data explosion brings new challenges to massive data transmission and data migration to the c...

Problems solved by technology

[0005] The first is to build a point-to-point network dedicated line, and the data is transmitted through the external network. It is necessary to deploy a migration cluster. The process of reading source data and writing destination data consumes bandwidth and other resources. The overall migration cycle is long and time-consuming. The cost of bandwidth and dedicated line high construction cost

Internet bandwidth costs are very expensive compared to logistics and transportation costs

[0006] The second is to copy the data to the hard disk in the local data center, and send multiple hard disks at one time to go to the enterprise logistics. After receiving the hard disks, the cloud will read the data and upload it to the cloud storage server. This method has a limited number of hard disks sent at a time. less data security

Unsuitable for mass data transmission to the cloud
