Built for reliability

Everything you need for NAS backups

Designed to be set up once and forgotten. Reliable, efficient, and always there when you need it.

Push-only HTTPS

Your NAS pushes backups out — Datashelter never connects in. No inbound ports, no firewall changes, no exposed admin panels.

Native to every major NAS

Runs on QNAP, Synology, TrueNAS, and OpenMediaVault. Native plugins are on the way; the agent works today.

Restore to any device

Restore a single file or a full share — to the same NAS, a different one, or a Linux server. Your data, your call.

Scheduling, made easy

Hourly, daily, weekly — no crontabs.

Guided setup walks you through your backup cadence in one step. Pick a frequency, pick a window — the agent handles the rest.
