Version 3.12.0

3.8.2. Start metrics server

On-premise

To start nxs-backup in server mode on-premise just run the command:

nxs-backup server

If the server settings are specified correctly, the nxs-backup application will start and process requests until it is interrupted.

You can add a system unit for convenience.

[Unit]
Description=Nxs-backup

[Service]
ExecStart=/usr/sbin/nxs-backup server

[Install]
WantedBy=multi-user.target

Docker-compose

To start nxs-backup in server mode with docker-compose add new service with shared metrics volume.

services:
  ...
  metrics-server:
    image: nixyslab/nxs-backup:latest
    container_name: nxs-backup
    command:
      - nxs-backup
      - -c
      - /nxs-backup.conf
      - server
    volumes:
      - metrics:/tmp/metrics
    configs:
      - nxs-backup.conf

volumes:
  metrics:

Also, specify the path to the metrics file in the nxs-backup config to be in the shared volume.

server:
  metrics:
    metrics_file_path: /tmp/metrics/nxs-backup.metrics

You can find a ready-made example in our repo.

Kubernetes/OpenShift

To start nxs-backup in server mode with Kubernetes/OpenShift cluster add a deployment with nxs-backup server to your nxs-universal-chart values. Specify the path to the metrics file in the volume.
