Abstract: A write-once-read-many (WORM) storage system that employs large-capacity and relatively inexpensive disks in connection with a file system on a file server is pro-vided. The file system contains most or all of the required WORM functionality so as to impose a minimal footprint on client applications, client operating systems and open protocols if desired. The system is organized around WORM storage volumes that contain files that, when committed to WORM storage, cannot be deleted or modified. Any file path or directory tree structure used to identify the file within the WORM vol-ume is locked and cannot be deleted. In one embodiment, the administrator creates a WORM volume, capable of storing designated WORM files. The client then creates an appropriate WORM file using the appropriate protocol semantics. The file is written to the volume and committed by transitioning the file attributes from a not-read-only to a read-only state. The file system recognizes the persistently stored WORM attribute of any file in a WORM volume as WORM file. Henceforth, any attempt to modify the file attributes, write to the file, or delete the file, by clients, administrators or other en-tities is rejected and a request denied message is returned to the attempting party.

Abstract translation: 提供了一次多次写入（WORM）存储系统，该系统在文件服务器上的文件系统中使用大容量且相对便宜的磁盘。 文件系统包含大部分或全部所需的WORM功能，以便在客户端应用程序，客户端操作系统和开放式协议（如果需要）上施加最小的占用空间。 系统围绕包含文件的WORM存储卷组织，当提交到WORM存储时，不能删除或修改。 用于标识WORM卷中的文件的任何文件路径或目录树结构都被锁定，无法删除。 在一个实施例中，管理员创建能够存储指定的WORM文件的WORM卷。 然后，客户端使用适当的协议语义创建一个适当的WORM文件。 将文件写入卷并通过将文件属性从非只读状态转换为只读状态来提交。 文件系统将WORM卷中任何文件的持久存储的WORM属性识别为WORM文件。 此后，客户端，管理员或其他机构修改文件属性，写入文件或删除文件的任何尝试都被拒绝，请求被拒绝的消息被返回给尝试方。

Abstract: A write-once-read-many (WORM) storage system (116, 160) that employs large-capacity and relatively inexpensive disks (240, 245) in connection with a file system on a file server (112) is provided. The file system contains most or all of the required WORM (116, 160) functionality so as to impose a minimal footprint on client applications, client operating systems and open protocols if desired. The system is organized around WORM storage volumes that contain files (418) that, when committed to WORM storage (402), cannot be deleted or modified. Any file path or directory tree structure (418) used to identify the file within the WORM volume is locked and cannot be deleted. The administrator creates a WORM volume (302), capable of storing designated WORM files (418). The client then creates an appropriate WORM files (304) using the appropriate WORM file using the appropriate protocol semantics. The file is written to the volume and committed by transitioning the file attributes from a not-read-only to a read-only state 9, (506).
