Move your Unraid server backups offsite
Unraid has no native enterprise backup target: we lean on what your stack already exposes. rsync via User Scripts or a restic / rclone container push your shares, over a dedicated VPN, to the Nimbus Backup Gateway — then protected by PBS, AirGap and LTO.
The method depends on your container
On Unraid there is no single enforced backup tool: the flexibility comes from Community Apps. The User Scripts plugin lets you schedule an rsync task with nothing else to install; to target SFTP, FTP, WebDAV or S3, you go through a restic or rclone container. So the available path depends on what you already run. The Gateway accepts both and saves you from maintaining a second remote Unraid box. Not sure which path? See the choose the right backup method guide and the protocols matrix. On a different source? See offsite backup for a QNAP NAS or offsite Linux server backup.
Recommended protocol
Two clean options, depending on whether you want a simple mirror or encrypted deduplication.
rsync via User Scripts
The lightest path: a task scheduled by the User Scripts plugin, no extra container. Ideal for a file mirror of your shares to the Gateway. rsync preserves the tree and only transfers deltas.
restic → SFTP / S3
The most robust path: a restic (or rclone) container writing over SFTP or S3 to the Gateway, with deduplication, versioned snapshots and source-side encryption. Prefer it as soon as volume or retention matters.
Shared doctrine: everything flows through a dedicated VPN (zero inbound ports), the Gateway buffers, then Nimbus replicates to immutable PBS, AirGap PBS and LTO. The Gateway multiplexes your non-Proxmox sources; your Proxmox VMs go straight from PVE → PBS.
How it works, step by step
Four steps, without touching the array or your production containers.
Dedicated VPN
We set up an encrypted tunnel (WireGuard or OpenVPN) between your Unraid server and the Gateway. Nothing is exposed in clear text: your server opens an outbound tunnel, no inbound ports to open.
rsync (User Scripts) or restic
An rsync task scheduled by the User Scripts plugin pushes your shares to the Gateway, or a restic/rclone container writes over SFTP/S3 with dedup and encryption. Your array stays untouched.
Nimbus replicates multi-PBS + AirGap
The Gateway buffers the backup, then Nimbus protects it to a Primary PBS — and optionally a disconnected AirGap PBS and an LTO tape in a vault. Retention and immutability on the PBS side.
Restore test
We validate a real restore from the Nimbus chain to guarantee your Unraid shares are recoverable, then sign off the go-live.
From your Unraid to the air-gap
A single backup can be replicated to several PBS, then archived to tape, depending on the PBS plan you subscribe to.
Pricing and plans
The Gateway Cloud starts at 150EUR excl. tax/month (2 TB included, 99EUR setup); the full six plans, the Appliance option, the antivirus scan and the PBS tiers are on the offsite NAS backup hub.
