一种数据存取方法及系统
摘要：
本发明公开了一种数据存取方法及系统，包括：接收用户终端发送的数据存储请求消息，所述数据存储请求消息中至少携带有用户终端的地理位置信息和请求存储的数据；根据用户终端的地理位置信息确定用户终端所属的地理区域，并查找出为该地理区域的用户终端分配的主数据中心和从数据中心；将请求存储的数据存储到查找到的主数据中心，并将主数据中心的数据备份到从数据中心。由于，从数据中心存储了备份数据，因此，在主数据中心出现故障或者发生不可抗拒的灾难而致使存储在主数据中心的数据被破坏时，可以使用从数据中心存储的备份数据，因此，本发明实施例提供的数据存取方法为用户终端提供了稳定的数据存取服务。
摘要（英）：

The invention discloses a data access method and a data access system. The data access method comprises the steps: receiving a data storage request message sent by a user terminal, wherein the data storage request message at least carries geographical position information of the user terminal and data requested to be stored; determining a geographical region to which the user terminal belongs according to the geographical position information of the user terminal, and finding out a master data center and a slave data center for distributing the user terminal in the geographical terminal; storing the data requested to be stored into the found master data center, and backing up the data in the master data center into the slave data center. The data are backed up into the slave data center, so that the backup data stored in the slave data center can be used when the data stored in the master data center are damaged as the master data center is faulted or an irresistible disaster happens; therefore, the data access method provided by the embodiment of the invention provides stable data access service for the user terminal.
