1. A method for synchronizing a terminal mirror, comprising: obtaining, by a terminal, multiple input events during running of application software; aggregating, by the terminal, the multiple input events to obtain an aggregate event; transmitting, by the terminal, the aggregate event to a server, so that after parsing the aggregate event to obtain the multiple input events, the server processes the multiple input events by using a virtual machine that is of the terminal and set on the server, so as to obtain user data generated during the running of the application software; wherein aggregating, by the terminal, the multiple input events to obtain an aggregate event comprises: obtaining, by the terminal, one current input event according to a generating sequence of the multiple input events, generating, by the terminal, bitmap information for each piece of attribute information of the current input event, wherein the bitmap information of each piece of attribute information is used to indicate whether the attribute information is the same as corresponding attribute information of a preceding input event of the current input event, determining, by the terminal, the bitmap information and attribute information, which is different from that of the preceding input event, of the current input event as data to be transmitted of the current input event, and combining, by the terminal after determining data to be transmitted of each input event of the multiple input events, the data to be transmitted of the multiple input events to form the aggregate event of the multiple input events.
