Vykar is a fast backup utility written in Rust that creates encrypted, deduplicated snapshots of data and stores them in local or remote repositories.
It is designed as an all-in-one backup solution with a simple YAML configuration file, built-in scheduling, and tools for backup, restore, and monitoring without relying on multiple external utilities or scripts.
This is free and open source software.
Key Features
- Storage backends – local filesystem, S3 (any compatible provider), SFTP, dedicated REST server.
- Encryption with AES-256-GCM or ChaCha20-Poly1305 (auto-selected) and Argon2id key derivation.
- YAML-based configuration with multiple repositories, hooks, and command dumps for monitoring and database backups.
- Deduplication via FastCDC content-defined chunking with a memory-optimized engine (tiered dedup index + mmap-backed pack assembly).
- Compression with LZ4 or Zstandard.
- Built-in WebDAV and desktop GUI to browse and restore snapshots.
- REST server with append-only enforcement, quotas, and server-side compaction.
- Concurrent multi-client backups – multiple machines back up to the same repository simultaneously; only the brief commit phase is serialized.
- Built-in scheduling via vykar daemon – runs backup cycles on a configurable interval (no cron needed).
- Resource limits for worker threads, backend connections, and upload/download bandwidth.
- Cross-platform support – runs under Linux, macOS, and Windows
