Deployment

Node Agent

Run this on every Incus host:

cd /opt/incus-backup-ui/backend
cp .env.example .env
npm install
sudo npm start

Important .env values:

HOST="0.0.0.0"
PORT=3000
API_TOKEN="long-random-token-at-least-32-characters"
HTTPS_ENABLED=true
TLS_CERT_FILE="/etc/incus-backup-agent/tls.crt"
TLS_KEY_FILE="/etc/incus-backup-agent/tls.key"
ALLOWED_MANAGEMENT_IPS="management-server-ip"

API_TOKEN is required and must be at least 32 characters long. If ALLOWED_MANAGEMENT_IPS is set, the agent only accepts requests from those comma-separated IP addresses.

For private networks such as NetBird, the agent can serve HTTPS directly with an internal CA. Create one CA and sign one certificate per agent. The certificate must contain the NetBird IP or internal DNS name as a SAN:

sudo install -d -m 700 /etc/incus-backup-agent
openssl genrsa -out agent-ca.key 4096
openssl req -x509 -new -nodes -key agent-ca.key -sha256 -days 3650 -out agent-ca.crt -subj "/CN=Incus Backup Agent CA"
openssl genrsa -out tls.key 4096
openssl req -new -key tls.key -out tls.csr -subj "/CN=incus-node-1"
printf "subjectAltName=IP:100.127.0.10,DNS:incus-node-1.netbird\n" > tls.ext
openssl x509 -req -in tls.csr -CA agent-ca.crt -CAkey agent-ca.key -CAcreateserial -out tls.crt -days 825 -sha256 -extfile tls.ext
sudo install -m 600 tls.key /etc/incus-backup-agent/tls.key
sudo install -m 644 tls.crt /etc/incus-backup-agent/tls.crt

Copy agent-ca.crt to the management server and set AGENT_CA_FILE there.

Install systemd service:

sudo cp deploy/systemd/incus-backup-agent.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now incus-backup-agent
sudo journalctl -u incus-backup-agent -f

Management API

Run this on the management server:

cd /opt/incus-backup-ui/management
cp .env.example .env
npm install
npm start

Important .env values:

PORT=3100
SESSION_SECRET="long-random-secret"
AUTH_USERNAME="admin"
AUTH_PASSWORD="initial-password"
DATABASE_PATH="./management.sqlite"
CORS_ORIGINS="https://backup.example.com"
SESSION_COOKIE_SECURE=true
ALLOW_INSECURE_AGENT_HTTP=false
AGENT_CA_FILE="/etc/incus-backup-management/agent-ca.crt"

AUTH_PASSWORD is required for the first start when the user database is empty. CORS_ORIGINS must list the frontend origins that are allowed to use cookie-authenticated API calls. Agent URLs must use https://; only set ALLOW_INSECURE_AGENT_HTTP=true for local development. AGENT_CA_FILE should point to the CA certificate that signed the internal agent certificates.

Reset an existing password:

npm run reset-password -- admin "new-password"

Install systemd service:

sudo useradd --system --home /opt/incus-backup-ui --shell /usr/sbin/nologin incus-backup
sudo chown -R incus-backup:incus-backup /opt/incus-backup-ui/management
sudo cp deploy/systemd/incus-backup-management.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now incus-backup-management
sudo journalctl -u incus-backup-management -f

Frontend

Point the frontend at the management API:

cd /opt/incus-backup-ui/frontend
npm install
VITE_API_URL=http://management-server:3100/api npm run build
npm run preview -- --host 0.0.0.0

For production, put the frontend and management API behind HTTPS.
