Abstract:
In accordance with one or more embodiments, an inode implemented file system may be utilized to support both offline and inline deduplication. When the first content is stored in the storage medium, one inode is used to associate a filename with the data blocks where the first content is stored. When a second content that is a duplicate of the first content is to be stored, then a parent inode is created to point to the data blocks in which a copy of the first content is stored. Further, two inodes are created, one representing the first content and the other representing the second content. Both inodes point to the same parent inode that points to the data blocks where the first content is stored.
