本发明的核心思想是采用虚拟化技术，将远程数据中心中的数据以虚拟磁盘的形式呈现给用户，凭此简化用户操作和管理的复杂度。The core idea of the present invention is to adopt the virtualization technology to present the data in the remote data center to the user in the form of a virtual disk, thereby simplifying the complexity of user operation and management.
图1为本发明系统实施例的组成示意图。如图1所示，该系统实施例主要包括传输模块110、生成模块120、编辑模块125、第二管理模块130、比较模块140、第三管理模块150、接口模块160、镜像模块170、第四管理模块180以及日志信息模块190，其中：Fig. 1 is a schematic composition diagram of a system embodiment of the present invention. As shown in Figure 1, the system embodiment mainly includes a
传输模块110，与远程数据中心200相连，用于与远程数据中心200进行文件元数据信息以及文件内容等的交互，包括从远程数据中心200获取待处理文件的文件元数据信息以及文件内容，和根据第三管理模块150所生成的协议标签以及接口模块160所确定的协议接口，向远程数据中心200传输该待传输数据；并将第四管理模块180生成的虚拟磁盘的使用信息和日志信息模块190生成的虚拟磁盘的日志信息发送给远程数据中心200进行保存；The
生成模块120，与该传输模块110相连，用于根据该文件元数据信息生成虚拟磁盘，通过该虚拟磁盘将该文件内容显示给用户；The generation module 120 is connected with the
编辑模块125，用于用户通过该虚拟磁盘，对该虚拟磁盘所显示的文件内容进行的编辑，在虚拟磁盘中保存编辑结果；The
第二管理模块130，用于从存储在虚拟磁盘上的配置文件中获得配置信息，其中该配置信息包括用户信息、虚拟磁盘元数据信息等；The second management module 130 is configured to obtain configuration information from a configuration file stored on the virtual disk, where the configuration information includes user information, virtual disk metadata information, etc.;
比较模块140，用于以文件为单位，比较待处理文件在本地虚拟磁盘和远程数据中心200之间的差异(即虚拟磁盘中所保存的编辑结果与远程数据中心200中发送给传输模块110的文件内容)，获得待处理文件在远程数据中心200和本地虚拟磁盘之间的差量信息；The
第三管理模块150，用于根据第二管理模块130获得的该配置信息和比较模块140获得的该差量信息，针对具体应用环境从http、https、ftp、NFS和CIFS等众多路由协议中选择一种路由协议，根据该路由协议将该差量信息生成待传输数据，并根据所选的路由协议制作协议标签，为该待传输数据贴上该协议标签；The
接口模块160，用于根据协议标签确定第三管理模块150生成待传输数据时所选用的路由协议，并根据所确定的路由协议提供相应的协议接口；The interface module 160 is configured to determine the routing protocol selected by the
镜像模块170，与该传输模块110及第三管理模块150相连，用于传输该待传输数据时，在本地对待传输数据进行镜像处理，获得镜像数据；The
第四管理模块180，与传输模块110及日志信息模块190相连，用于管理虚拟磁盘的使用权限，生成虚拟磁盘的使用信息并发送给传输模块110；其中该使用权限至少包括新建用户、修改用户属性、删除用户等基本功能；The fourth management module 180 is connected with the
日志信息模块190，与该传输模块110及第四管理模块180相连，用于根据该第四管理模块180对虚拟磁盘的使用权限进行管理、用户对待处理文件进行编辑以及传输模块110与远程数据中心等，生成虚拟磁盘的日志信息并发送给传输模块110。The
上述系统实施例为用户提供了一个管理和编辑远端数据中心文件、数据信息的一个非常便利的渠道，用户可以根据所拥有的权限对这个虚拟磁盘的文件进行读、写、新建、删除等编辑操作，该操作如同对本地磁盘的数据进行的操作一样。The above-mentioned system embodiment provides a very convenient channel for users to manage and edit files and data information in the remote data center. Users can read, write, create, delete, etc. edit the files of this virtual disk according to the permissions they have. Operation, the operation is the same as the operation on the data on the local disk.
上述系统实施例屏蔽了众多路由协议的具体实现方式，为多种协议提供了一个统一的传输接口。上述系统实施例有效地避免了用户使用基于不同协议的客户端工具来进行文件等数据的传输，为用户提供了统一的操作方式(虚拟磁盘)，用户无需知道底层实现的是哪种具体的协议；该屏蔽功能主要通过协议路由功能来实现，比如现有技术中用户如果要利用ftp协议传输文件的语，就需要用ftp的工具，本发明基于上述屏蔽功能，用户就可以利用统一的操作方式(虚拟磁盘)来对ftp、CIFS、http等协议进行文件、数据的传输。The above-mentioned system embodiment shields the specific implementation methods of many routing protocols, and provides a unified transmission interface for multiple protocols. The above system embodiment effectively prevents users from using client tools based on different protocols to transmit data such as files, and provides users with a unified operation mode (virtual disk), and users do not need to know which specific protocol is implemented at the bottom layer The shielding function is mainly realized by the protocol routing function. For example, in the prior art, if the user wants to utilize the ftp protocol to transfer the language of the file, the tool of ftp is needed. The present invention is based on the above-mentioned shielding function, and the user can use the unified operation mode (virtual disk) to transfer files and data to ftp, CIFS, http and other protocols.
上述比较模块140使得远程数据中心200和本地数据只需交换不同的部分，因而使用该模块可有效节约网络带宽，增加了传输效率。The
上述镜像模块170在数据开始传输时建立镜像缓存，获得镜像数据。此时，在镜像缓存和虚拟磁盘上各有一份镜像数据。在成功完成数据传输后释放镜像缓存和虚拟磁盘上的镜像数据，这样有效地保障了传输过程中的数据一致性与容错性。因为数据是存储在远端数据中心，所以传输过程中因为突然断电等导致传输中断，则待系统正常工作后可以根据镜像模块170中的镜像数据恢复并完成传输。The above-mentioned
图2为本发明方法实施例的流程示意图。结合图1所示的系统实施例，图2所示的方法实施例主要包括如下步骤：Fig. 2 is a schematic flow chart of a method embodiment of the present invention. In conjunction with the system embodiment shown in Figure 1, the method embodiment shown in Figure 2 mainly includes the following steps:

步骤S230，在本地和远程数据中心之间传输数据前，先得到用户的操作权限，如果有允许传输的操作权限，则从存储在磁盘上的配置文件中获得配置信息；其中该配置信息包括用户信息、虚拟磁盘元数据信息等；Step S230, before transferring data between the local and remote data centers, first obtain the user's operation authority, if there is an operation authority to allow transmission, then obtain configuration information from the configuration file stored on the disk; wherein the configuration information includes user information, virtual disk metadata information, etc.;

步骤S260，针对具体应用环境，并根据配置信息及差量信息，从http、https、ftp、NFS和CIFS等众多路由协议中选择一种路由协议，并根据该路由协议生成待传输数据以及制作协议标签，为该待传输数据贴上该协议标签；Step S260, according to the specific application environment, and according to the configuration information and the difference information, select a routing protocol from many routing protocols such as http, https, ftp, NFS and CIFS, and generate data to be transmitted and make a protocol according to the routing protocol Label, affix the protocol label to the data to be transmitted;
步骤S270，进行数据传输时，从该待传输数据剥去该协议标签，根据协议标签的内容确定待传输数据所选用的路由协议，并根据所确定的路由协议提供相应的协议接口；Step S270, when performing data transmission, strip the protocol label from the data to be transmitted, determine the routing protocol selected for the data to be transmitted according to the content of the protocol label, and provide a corresponding protocol interface according to the determined routing protocol;
步骤S280，根据该协议标签及协议接口，向远程数据中心传输待传输数据；并对该待传输数据进行镜像缓存，获得镜像数据；Step S280, according to the protocol label and the protocol interface, transmit the data to be transmitted to the remote data center; and perform mirroring and buffering on the data to be transmitted to obtain the mirrored data;
步骤S290，传输成功结束后根据文件系统类型对文件元数据、文件内容等信息进行组织，并清除镜像数据。In step S290, after the transmission is successfully completed, the file metadata, file content and other information are organized according to the file system type, and the image data is cleared.
至此，一次在线存储系统本地数据与远程数据中心的数据传输结束，并且，一个可以管理远程数据中心数据、文件信息的虚拟磁盘与远程数据中心的数据交互成功结束。So far, the data transmission between the local data of the online storage system and the remote data center is completed, and the data interaction between a virtual disk that can manage the data and file information of the remote data center and the remote data center is successfully completed.
