    • Embodiments of the present invention disclose a method and a system for information synchronization between cloud storage gateways and a cloud storage gateway, to resolve a problem that an address obtained by a cloud storage gateway is usually a dynamic address or even a private address, and it is difficult to perform direct communication and impossible to perform directory synchronization. The foregoing method includes: obtaining, by a first cloud storage gateway and from a cloud message queue of a cloud service provider, a first directory message distributed by a second cloud storage gateway; obtaining, by the first cloud storage gateway, a cloud storage directory; and merging, by the first cloud storage gateway, a directory of the first cloud storage gateway, a directory of the second cloud storage gateway, and the cloud storage directory into one directory, and displaying the directory. In this embodiment, a cloud storage gateway obtains, from a cloud message queue of a cloud service provider, a directory distributed by another cloud storage gateway; and therefore, as long as the cloud storage gateway can communicate with the cloud service provider, directory synchronization can be implemented without a need of direct communication between the cloud storage gateways. Therefore, even through an address obtained by the cloud storage gateway is a dynamic address or a private address, directory synchronization is not affected.
    • 本发明的实施例公开了一种用于云存储网关和云存储网关之间的信息同步的系统,来解决问题做了由云存储网关地址上而获得通常是一个动态地址或甚至是私有地址,并且它 难以进行直接通信,也不可能执行目录同步。 前述方法包括:获取由第一云存储网关和从云服务提供商,通过第二云存储网关分发的第一目录信息的云消息队列; 获得,由所述第一云存储网关,云存储目录; 和合并由所述第一云存储网关,第一云存储网关的一个目录,云第二存储网关的一个目录中,和云存储目录成一个目录,并且显示该目录。 在此,实施例的云存储网关获取,从云服务提供商,由另一个云存储网关分布式目录的云消息队列; 因此,只要云存储网关可以与云服务提供商进行通信,目录同步可以,而不需要云存储网关之间的直接通信的执行。 因此,即使通过,以解决云存储网关获得是一个动态的地址或私有地址,目录同步不受影响。
