Abstract
A storage system for backup data of a flash memory includes a flash memory for storing a first file, a detector for detecting a number of accesses to the first file, and a driving unit coupled to the detector. The driving unit is used for duplicating the first file as one or more second files when the number of accesses to the first file exceeds a predetermined value, and storing the one or more first files into the flash memory. If the access number is higher than the predetermined value, which indicates this file is more likely to be accessed, the invention automatically backups this file and accesses the backup file at the next access request for fear that the file is damaged by multiple access to the same file.
