Windows, macOS, and Linux
One backup tool across every desktop - a native app, a terminal interface, and a command line - fully localized in 24 languages.
Encrypted, deduplicated backups to storage you already own - with real snapshot restore, scheduling, and retention, across Windows, macOS, and Linux.
Files, names, folder structure, and manifests are encrypted locally with AES-256-GCM using a key derived from your passphrase. We never receive your data or your keys - and could not read them if we were asked to.
Content-defined chunking with deduplication and zstd compression means only the parts of files that actually changed are uploaded. After the first backup, runs are quick and light on bandwidth and storage.
Every backup is a point-in-time snapshot. Browse them, preview the tree, and restore a single file, a folder, or everything - to this machine or another - exactly as it was, right in the app.
Back up on a schedule with battery and network guards, and keep the history you want with flexible retention (daily / weekly / monthly / yearly). Old snapshots prune automatically; your only copy is never at the mercy of a manual step.
Point Nyx Backup at a destination you control. You hold the account and the keys - we never store, proxy, or see your data. No storage fees from us.
One backup tool across every desktop - a native app, a terminal interface, and a command line - fully localized in 24 languages.
Your license is a signed file verified entirely offline. No account, no validation server. Optional, anonymous usage telemetry you can switch off.
The archive format is documented and versioned (see the format spec), so your data stays independently recoverable for the long haul.
