Systems and methods for write-once-read-many storage

The disclosed computer-implemented method for write-once-read-many storage may include (1) receiving, at a file system on the computing device, a request to assign a write-once-read-many (WORM) attribute to a file, wherein the request is received from an application, (2) setting, in response to the request to assign the WORM attribute to the file, a WORM flag in an extended attribute associated with the file, and (3) associating with the file, in response to the setting of the WORM flag, a retention period attribute and read-only access until the end of the retention period. The provided systems and methods may provide per-file WORM support at a file system level using extended attributes of the file system. Various other methods, systems, and computer-readable media are also disclosed.
