Abstract: Embodiments of the present invention disclose a method and an apparatus for implementing protection of RAID in a file system, and are applied in the field of communications technologies. In the embodiments of the present invention, after receiving a file operation request, the file system needs to determine the type of a file to be operated as requested by the file operation request, and perform file operations in a hard disk drive of the file system directly according to a file operation method corresponding to the determined file type, that is, a RAID data protection method. Therefore, corresponding file operations may be performed in a proper operation method according to each different file types, and data of an important file type is primarily protected, thereby improving reliability of data storage.
