  • Data-Volumes
  • Environment Variables
• Networking
• Maintenance
  • Shell Access

• Assumes you are using some sort of SSL terminating reverse proxy such as:
  • Traefik
  • Nginx
  • Caddy
• Make sure there is adequate storage available to perform deduplicated backups!

Clone this repository and build the image with docker build -t (imagename) .

Builds of the image are available on Docker Hub

docker pull docker.io/tiredofit/backuppc:(imagetag)

Builds of the image are also available on the Github Container Registry

docker pull ghcr.io/tiredofit/docker-backuppc:(imagetag)

The following image tags are available along with their tagged release based on what's written in the Changelog:

• The quickest way to get started is using docker-compose. See the examples folder for a working docker-compose.yml that can be modified for development or production use.

• Set various environment variables to understand the capabilities of this image.

• Map persistent storage for access to configuration and data files for backup.

• Enter inside the container and as user backuppc ssh-copy-id your public keys to a remote host

• Visit your Web interface

The following directories are used for configuration and can be mapped for persistent storage.

This image relies on an Alpine Linux or Debian Linux base image that relies on an init system for added capabilities. Outgoing SMTP capabilities are handlded via msmtp. Individual container performance monitoring is performed by zabbix-agent. Additional tools include: bash,curl,less,logrotate, nano.

Be sure to view the following repositories to understand all the customizable options:

By default, this image does not use authentication. This is definitely not recommended on a production environment! Based on the environment variables from the Nginx Base Image you can set them here:

It's highly recommend you set at minimum:

NGINX_AUTHENTICATION_TYPE=BASIC
NGINX_AUTHENTICATION_BASIC_USER1=backuppc
NGINX_AUTHENTICATION_BASIC_PASS1=backuppc

When working with NGINX_AUTHENTICATION_LLNG_ATTRIBUTE2 you will need to omit any $ chracters from your string. It will be added in upon container startup. Example: NGINX_AUTHENTICATION_LLNG_ATTRIBUTE1=HTTP_AUTH_USER,uid,upstream_http_uid will get converted into HTTP_AUTH_USER,$uid,$upstream_http_uid and get placed in the appropriate areas in the configuration.

See the MSMTP Configuration Options for further information on options to configure MSMTP.

The following ports are exposed and available to public interfaces

NOTE: It is highly recommended this be run through a SSL proxy, or via localhost and tunnel via SSH.

For debugging and maintenance purposes you may want access the containers shell.

docker exec -it (whatever your container name is) bash
