Duplicati has been our primary file backup solution for years, it offers stability and features that can only be found in premium backup solution services.

You can also use duplicati for your own personal use, it also offers support for all major operating system platforms like Windows, Mac, and Linux.

Getting Started: How to Install Duplicati

As we mention in the introduction we use duplicati in our own server, there are many installation method that we can use to install it, but in this article we will only cover docker as our main installation method. Here are steps by steps how to install it using docker

1. Install docker and docker-compose in your machine
2. Create a docker-compose.yml in any directory you want e.g (/home/server/container/duplicati/docker-compose.yml)

   version: "2.1"
   services:
     duplicati:
       image: linuxserver/duplicati
       container_name: duplicati
       restart: always
       environment:
         - PUID=0
         - PGID=0
         - TZ=UTC+7
         - CLI_ARGS= #optional
       volumes:
         - ./config:/config
         - /path/to/backup/source:/path/to/backup/source
       ports:
         - 8200:8200

   Notes : Please don’t forget to change the /path/to/backup/source with your backup source directory

3. Run the container by executing command :

   docker-compose up -d
