Information synchronization method and system between cloud storage gateways, and cloud storage gateway

Abstract

The embodiment of the present invention discloses a method and system for synchronizing information between cloud storage gateways, and a cloud storage gateway, so as to solve the problem that the addresses obtained by the cloud storage gateway are usually dynamic addresses or even private network addresses, and direct communication is difficult and directory synchronization cannot be performed. . The above method includes: the first cloud storage gateway obtains, from the cloud message queue of the cloud service provider, the first directory message published by the second cloud storage gateway; the first cloud storage gateway obtains the cloud storage directory; The directory of the cloud storage gateway, the directory of the second cloud storage gateway, and the cloud storage directory are displayed in combination. In the embodiment of the present invention, the cloud storage gateway obtains directories published by other cloud storage gateways from the cloud message queue of the cloud service provider. As long as the cloud storage gateway can communicate with the cloud service provider, the directory synchronization can be realized. No direct communication is required. Therefore, even if the address obtained by the cloud storage gateway is a dynamic or private network address, it does not affect directory synchronization.

Description

Technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for information synchronization between cloud storage gateways, and a cloud storage gateway. Background technique [0002] For enterprises with multiple branches, in a distributed deployment scenario, a cloud storage gateway is usually deployed in each branch of the enterprise, and multiple branches share a cloud service provider. Each cloud storage gateway usually merges the locally stored directory and the cloud storage directory into one directory and presents it to users in their respective branches, which leads to inconsistent content seen by users in each branch, and requires directory synchronization of the cloud storage gateway. [0003] At present, the cloud storage gateways of various branches realize directory synchronization through direct communication. Therefore, the cloud storage gateway of each branch is required to be directly reachable, and ...

AI Technical Summary

Problems solved by technology

[0004] However, in the actual deployment environment of small and medium-sized enterprises, the address obtained by the cloud storage gateway is usually a dynamic address or even a private network address. There are difficulties in direct communication, and directory synchronization cannot be performed.
