Demystifying Dropbox: A Deep Dive into the Cloud Storage System

TLDRLearn about the inner workings of Dropbox, including file upload and download processes, fault tolerance, and metadata storage.

Key insights

🔒Dropbox uses erasure coding for fault tolerance and data recovery in case of hardware failures.

💾When a user uploads a file, Dropbox stores it in small blocks and distributes them across multiple servers for redundancy.

📂Metadata about files, such as file name, size, and last modification date, is stored separately in a metadata store.

🔄Data deduplication and syncing algorithms allow Dropbox to efficiently manage file updates and synchronization across devices.

🔒Security measures, such as encryption and access control, are in place to protect user data and ensure privacy.
