With the development of IT technology, the amount of digital contents used in various environments of wired/wireless networks have been increased hugely and rapidly To protect the loss of the digital contents from the sudden accident, continuous data backup is required. In this paper, we design and implement the backup system that stores digital contents in backup storage by objectifying the contents with a unit of I/O size and giving them the unique E using the properties of digital contents to avoid duplicated store of the same data. The backup system reduces the amount of backup data efficiently by backing up the only one copy of the duplicated data. as a result, the backup system can back up the digital contents more efficiently in a constrained storage space.
