- * With 'md5_outside', md5 is used to hash the first part of the file, the last part of the file. This method offer file deduplication at minimal cost but can be dangerous as files with the same partial hash can be mistaken.
- * With 'random', file hash not set to a random value and file deduplication cannot work anymore but it is fast and safe.
- * and the file's size. This method is fast for large files but cannot be perfect.
