Abstract: 본발명은 (a) 쓰기요청된데이터를하나이상의데이터조각으로분할하는단계; (b) 상기분할된각 데이터조각을제 1차중복검사를통해사본없음과사본존재가능으로분류한후, 상기분류된데이터조각을각각상기공유데이터저장소의해당구획에저장하는단계; (c) 상기공유데이터저장소에대한읽기또는쓰기요청이없을때, 제 2차중복검사를통해, 상기 (b) 단계에서사본존재가능으로분류된데이터조각중에서사본이존재하는데이터조각을선별하는단계; 및 (d) 상기공유데이터저장소에대한읽기또는쓰기요청이없을때, 상기 (c) 단계에서상기사본이존재하는것으로확인된데이터조각을제거하는단계를포함하되, 상기제 1차중복검사에사용되는해시방법은상기제 2차중복검사에사용되는해시방법보다충돌확률이높지만해시값 생성속도가빠른것인공유데이터저장소관리방법을제공한다.

Abstract: PURPOSE: A shared data storage management device and a method thereof are provided to secure the uniqueness of shared data by dealing with the issue of data redundancy. CONSTITUTION: When a writing request regarding certain data is received (S310), the requested data is divided into pieces (S320). The pieces of data are grouped and stored either in a no-copy section or in a copy-likely section according to the result of a first redundancy examination (S330). When a data storage (20) is idle (S340), a second redundancy examination is carried out to identify the pieces of data which have their copy (S350) and a garbage collection process follows (S350). [Reference numerals] (S310) Writing request?; (S320) Divide into pieces; (S330) Store partly both in a no-copy section and in a copy-likely section; (S340) Idle?; (S350) Identify the pages having copies from the copy-likely section; (S360) Collect garbage files
