FTP distributed video file processing method and system based on RAID disk

The invention relates to an FTP (File Transfer Protocol) distributed video file processing method and system based on an RAID (Redundant Array of Independent Disks) disk. The method comprises the following steps of: calculating the size of a to-be-uploaded video file, a hash value of file content and a hash value of file block content through an FTP client, and uploading to an FTP scheduling module; the FTP scheduling module searches whether a file with the same size and hash value as the to-be-uploaded video file exists in an FTP server, and if yes, the FTP scheduling module returns an FTP file address of the same file to the client; and if the file does not exist, selecting an optimal FTP server address to return to the client, and uploading the video file to the optimal FTP address by the client. According to the invention, the characteristic that the RAID0 is fast in file reading and writing is utilized, and meanwhile, an idle backup and file recovery module is added to ensure the security of the data, an
