Repository Overview (README excerpt)
Crawler viewVykar Backup A fast, encrypted, deduplicated backup tool written in Rust centered around a friendly YAML config file. Inspired by BorgBackup, Borgmatic, Restic, and Rustic. Vykar uses its own on-disk format and is not compatible with Borg or Restic repositories. **⚠️ Don't use for production backups yet, but do test it along other backup tools.** 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 — runs backup cycles on a configurable interval (no cron needed) • **Resource limits** for worker threads, backend connections, and upload/download bandwidth • **Cross-platform** — Linux, macOS, and Windows Benchmarks Vykar leads in both speed and CPU efficiency, while maintaining competitive memory usage. All benchmarks were run on the same idle Intel i7-6700 CPU @ 3.40GHz machine with 2x Samsung PM981 NVMe drives. Compression settings were chosen to keep resulting repository sizes comparable. The sample corpus is a mix of small and large files with varying compressibility. See our benchmark script for full details. Quick start Or download the latest release for your platform from the releases page. A Docker image is also available. See the full documentation for storage backends, restore, maintenance, and more. Desktop UI is a Slint-based desktop app that uses directly (it does not shell out to the CLI). • Run backups on demand • List snapshots and browse snapshot contents • Extract snapshot contents • Run in the system tray with periodic background backups • Uses as the source of truth and auto-reloads config changes Periodic GUI scheduling is configured in via: Security To report a security vulnerability, please email hello@borgbase.com.
