File management method and storage system |
摘要 |
Files stored in a storage system are grouped in a metadata server, and storage servers discretely storing these files are instructed to detect file duplication and to remove duplicate data. The storage servers detect duplicate data by comparing file fragments stored by the storage servers themselves with each other. In a case where duplicate data is detected, the storage servers delete the duplicate data. |
