SnapSafe

SnapSafe is a secure, and incremental backups tool with encryption and optional cloud upload. It is designed to protect your files through versioned snapshots and password-based encryption. It is built with simplicity and security in mind and allows you to specify files and directories you want to back-up/restore.

Features

• 📦 Incremental backup with snapshot versioning
• 🔐 AES-256 encryption with password-derived keys
• 📂 Restore to any snapshot version
• 🧾 List and delete snapshots
• 🧪 Built-in testable architecture

Installation

cargo build --release

Or add it as a local dependency in your Cargo.toml.

Example

snapsafe backup --source ~/Documents --dest /mnt/backups
snapsafe restore --origin ./restore --output ./after_restore

Security

SnapSafe encrypts your data using AES-256 in GCM mode. Passwords are processed using PBKDF2 or Argon2 to generate keys securely.

Roadmap

• ✅ Basic backup/restore/delete: See here...
• ⌛ Configurable compression/encryption, version diffing: See here...
• 🔜 Cloud sync (S3/GCS)
• 🔜 Daemon mode for scheduling
