slint 1.16 changed its muda dep from 0.17 to 0.18, while tray-icon 0.22 stayed on 0.17. Both versions register the Objective-C class `__CLASS_MudaMenuDelegate`, causing the macOS `vykar-gui` release binary to fail at link time: Linking globals named '__CLASS_MudaMenuDelegate': symbol multiply defined! error: failed to load bitcode of module "muda-…" tray-icon 0.23/0.24 use muda 0.19 (still ahead of slint 1.16's 0.18), and slint 1.16 is the latest published. Constrain slint and slint-build to `~1.15` until either slint catches up to muda 0.19 or a slint version using a matching muda is released. tray-icon stays at 0.22.2. |

Vykar 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
vykar daemon— runs backup cycles on a configurable interval (no cron needed), with an optional read-only HTTP status page - 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
curl -fsSL https://vykar.borgbase.com/install.sh | sh
Or download the latest release for your platform from the releases page. A Docker image is also available.
# Generate a starter config and edit it
vykar config
# Initialize the repository and run a backup
vykar init
vykar backup
# List snapshots
vykar list
See the full documentation for storage backends, restore, maintenance, and more.
Desktop UI
vykar-gui is a Slint-based desktop app that uses vykar-core 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
vykar.yamlas the source of truth and auto-reloads config changes
Periodic GUI scheduling is configured in vykar.yaml via:
schedule:
enabled: true
every: "24h"
on_startup: false
jitter_seconds: 0
passphrase_prompt_timeout_seconds: 300
