Abstract
The invention discloses a method for copying content in a desktop cloud system external device room. The method includes the steps that a storage address of data copy is judged; if the storage address is judged to be at a terminal, the terminal completes the data copy process through the calculating capacity of a terminal device, and the data copy operation does not need to be performed through a long-distance virtual machine. The method can reduce data copy time delay. Due to the fact the whole copy process is completed in the local place of the terminal device, participation of the long-distance virtual machine is not needed, the network communication process for transmitting data to the long-distance virtual machine and the network communication processor for transmitting the data back to the terminal device by the long-distance virtual machine can be eliminated, and meanwhile time delay caused by the two network communication processes can be eliminated. The method can further improve reliability of data copy and completely eliminate data transmission failure and other influences caused by network instability due to the fact that the network communication processes are eliminated.
