Introduction Features Implementation
◮ Divides data into content-sensitive chunks for efficient storage
◮ Stores chunks, indexed by chunk hashes ◮ Implements content-addressable storage ◮ Chunk fusion! Austin Clements, Dan Ports, Ben Schmeckpeper, Hector Yuen PersiFS: A Continuously Versioned Network File System
Introduction Features Implementation
◮ Divides data into content-sensitive chunks for efficient storage
◮ Stores chunks, indexed by chunk hashes ◮ Implements content-addressable storage ◮ Chunk fusion!
◮ Stores sequence of inode changes over time ◮ Uses periodic inode map snapshots for efficient replay ◮ Compact! Austin Clements, Dan Ports, Ben Schmeckpeper, Hector Yuen PersiFS: A Continuously Versioned Network File System
