1. A method of operating a machine-to-machine (M2M) device in an M2M system, the method comprising:
creating a first resource;
receiving a first message for requesting an update to the first resource; and
transmitting a second message for requesting an update to a second resource to an other device hosting the second resource synchronized with the first resource,
wherein the first resource comprises at least one attribute for offloading for a resource, and
wherein the synchronization is performed based on one of a first type where updating is propagated uni-directionally between a offloaded resource and to an original resource or a second type where updating is propagated bi-directionally one-way between a offloaded resource and to an original resource or a second type.
