Patent ID: 8589353

Claim:
A method for backing up terminal data, comprising following steps of: A, creating a terminal index table, wherein the terminal index table includes at least one terminal index item corresponding to terminal data; wherein, each terminal index item corresponds to one record of the terminal data, and the terminal index item includes a number field, a state field and an address field, wherein: the number field represents a serial number of the terminal index item; the state field is used for distinguishing a state of data corresponding to the terminal index item, and the state includes: an initial state, an unchanged state, a newly created state, a modified state and a deleted state; the address field is used for indicating a storage address of the terminal data corresponding to the terminal index item in the terminal device; B, a terminal device checking information in a terminal index item, wherein: if the state field of the checked terminal index item is the newly created state or the modified state, sending the number field of the terminal index item and a data content found according to the address field of the terminal index item to a network server, and modifying the state field of the terminal index item to the unchanged state; if the state field of the checked terminal index item is the deleted state, sending the number field of the terminal index item to a network server, so as to notify the network server to delete a data content corresponding to the number field, and modifying the state field of the terminal index item to the initial state; if the state field of the checked terminal index item is not any one of the unchanged state, the newly created state, the modified state and the deleted state, finding a data content according to the address field of the terminal index item, and sending the data content and the number field corresponding to the terminal index item to a network server; and C, the network server creating a server index table corresponding to the terminal index table, and executing a terminal data backup operation according to the information in the terminal index item, and modifying the server index table.
