Abstract
A method, apparatus, and system for interposed file system driver is provided, which provides a logical file system on top of an existing base file system. One such interposed file system driver is a compression and deduplication layered driver ('COLD driver'). File system operations are intercepted from the operating system through the COLD driver, which is provided as an upper-level operating system driver that operates on top of an existing base file system. By processing file data through various modules, the existing base file system can be extended as a logical file system with compression, deduplication, indexing, and other functionality. The COLD driver can be implemented without requiring modifications to existing base file system structures or base file system drivers. Server deployments may thus leverage the additional file system functionality provided by the COLD driver without having to migrate to another file system.
