A system and method for application-directed variable-granularity consistency management, in one embodiment, carries out the steps of: predefining a template specifying a structure of a file; imposing the template on the file including registering fields/records within the file for consistency; creating an index table for the file; detecting a write to the file, at one of a file system server and a file system client; and queuing, upon detecting the write to the file and in the event a portion of the file to which the write occurs is registered for consistency, the write for propagation to another of the file system server and the file system client. The system and method may employ an application program that predefines a template specifying a structure of a file and imposes the template on the file including registering fields/records within the file for consistency; and further employs a file system that creates an index table for the file; detects a write to the file, at one of a file system server and a file system client; and queues, upon detecting the write to the file and in the event a portion of the file to which the write occurs is registered for consistency, the write for propagation to another of the file system server and the file system client.
