Claim 12:
13. A data backup method, wherein the method being applied to a user terminal, and the method comprises:
sending, by a main controller in response to detecting a data backup request instruction of a user, a first signal switching instruction to a first multiplexer (MUX) and sending a second signal switching instruction to a second MUX;
receiving, by the first MUX, the first signal switching instruction, and connecting a second signal input end to a first signal output end according to the first signal switching instruction;
receiving, by the second MUX, the second signal switching instruction, and connecting a fourth signal input end to a second signal output end according to the second signal switching instruction; and
sending, by an interface controller, an input/output I/O instruction to a storage component to perform data backup processing in response to the second signal input end of the first MUX being connected to the first signal output end of the first MUX and the fourth signal input end of the second MUX being connected to the second signal output end of the second MUX.
