Claim 6:
7. A user terminal, wherein the user terminal comprises:
a storage component,
an input/output (I/O) controller,
a main controller,
an interface controller,
a first multiplexer (MUX),
a second MUX, and
a first interface, wherein:
the main controller being connected to each of a first signal selection input end of the first MUX and a second signal selection input end of the second MUX, and being configured to:
send a first signal switching instruction to the first MUX in response to a data backup request instruction of a user being received, and
send a second signal switching instruction to the second MUX;

a first signal input end of the first MUX being connected to the I/O controller;
a second signal input end of the first MUX being connected to the interface controller;
a first signal output end of the first MUX being connected to the storage component;
the first MUX being configured to connect the second signal input end to the first signal output end in response to the first signal switching instruction being received;
a third signal input end of the second MUX being connected to the I/O controller;
a fourth signal input end of the second MUX being connected to the interface controller;
a second signal output end of the second MUX being connected to the first interface;
the second MUX being configured to connect the fourth signal input end to the second signal output end in response to the second signal switching instruction being received; and
the interface controller being configured to:
send an I/O instruction to the 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.
