Abstract
A data backup method for backing up target data, through a driver module, from a first storage device to a second storage device is disclosed. The first storage device includes a first storage unit that stores the target data, and a first control unit that accesses the first storage unit based on a first logical-to-physical mapping table. The second storage device includes a second storage unit and a second control unit that accesses the second storage unit based on a second logical-to-physical mapping table. The method includes steps of: reading the target data from the first storage unit without accessing the first logical-to-physical mapping table and transmitting the target data to the driver module; transmitting the target data to the second control unit; and writing the target data to the second storage unit without accessing the second logical-to-physical mapping table.
