A1

Provided is a system for providing a hybrid worm disk, the system comprising: a network file server; and a network file server (NFS) client installed in a user terminal or a service server and communicatively connected to the network file server which is located remotely from the NFS client. Here, the network file server has a mode setting function which allows a disk drive, which is mounted in the form of a network drive in the user terminal or the service server, to operate in any one of a general disk mode in which creating, reading, modifying, deleting, and the like are possible, and a Write Once Read Many (WORM) disk mode in which only creating and reading are possible. The network file server can check whether a file with an identical filename exists, when a file creation request is received from the NFS client during the operation of the disk drive in the WORM disk mode, and can allow a corresponding file to be created within a preset change valid time range if no file with an identical filename exists.
