FileSync-Systems

Projects from my 3rd-year Systems Programming course at the National and Kapodistrian University of Athens.

This repository contains two file synchronization systems:

• FSS (FileSync System): Synchronizes local directories using Linux system calls, processes, and inotify.
• NFS (Network FileSync System): Synchronizes remote directories over the network using TCP sockets and threads.

🗂 Local FileSync System (fss/)

Monitors source directories and mirrors changes to target directories in real time. Built using:

• inotify for filesystem events
• fork/exec for spawning worker processes
• Named pipes for communication between manager and console

Supports commands like add, sync, cancel, status, and shutdown. Includes a bash script for reporting and cleanup.

🌐 Network FileSync System (nfs/)

Enables directory synchronization across machines over TCP. Components:

• nfs_manager: Coordinates tasks and threads
• nfs_client: Passive server for file operations
• nfs_console: User interface over TCP

Uses worker threads and a shared task queue to manage parallel file transfers. Clients support LIST, PULL, and PUSH commands.
