Agent Installation

This section details how the agent can be installed on a server. The main method is to use Bakup.io's settings page to add a server, and you will be given a one line command that will download and configure the agent automatically.

Automatic Installation#

  1. Generate an installation command by creating a new server on bakup.io

    https://bakup.io/dashboard/servers

  2. The installation must be executed as root, a service user called bakupagent is created for the agent to use and run under, or specify the ID of the user that you would like it to run as on the end of the installation command

    Whilst the installation script must be executed as root, the script will complete installation and then the agent will use the bakupagent user that is created. If you would like the agent to run as a different user, you can specify the user ID on the end of the installation command. The bakupagent service user does not get a home directory generated by default but you may create one for it if you like. The agent requires that systemctl is installed and usable.

  3. On the same server that your database (or other job types) instance is running, execute the provided command given to you via bakup.io, this will look like:

  1. After you have successfully installed an agent, this means you will have connected a server and it will now be able to communicate with bakup.io, you can now go and setup a database or file job and start backing up

Note: During automatic installation the process will compare hashes to make sure the correct binaries and files are downloaded and valid from bakup.io

Agent Permissions#

After you have successfully connected an agent, you will be able to see your server responding on the servers page. The agent uses (by default) the service user called bakupagent, you will have to make sure this user has the correct permissions when you setup a job.

Some situations you may need to consider when setting permissions:

  • Local storage providers, make sure the bakupagent service user has permissions to access the directories you have told it to backup to, otherwise the agent will report an error at bakup.io
  • Make sure the agent has the correct read and write permissions in relation to the jobs it will be running, you may have to give it permissions or access via chown or chmod
  • When backing up databases, make sure the bakupagent user has permission to run commands that are used to access and backup your database system

Manual Installation#

In the event that you would like to manually install the agent

  1. Three configuration files must be created

    mkdir -p /etc/opt/bakupagent
    touch /etc/opt/bakupagent/{USER_ID,CLIENT_ID,API_TOKEN}

  2. Populate USER_ID with the ID of the user you wish bakup agent to run under (the installation script will create a service user called bakupagent, this is recommended), then create CLIENT_ID and API_TOKEN with your Client ID and API Token, respectively.

    NOTE: Ensure that the CLIENT_ID and API_TOKEN files are writable by the user that will run the agent

  3. Copy the Bakup Agent and rclone binaries in to /opt/bakupagent/.

  4. After making the binaries executable, you can start the agent - ./opt/bakupagent/bakupagent

    NOTE: The Bakup Agent can be run with the -d argument to enable debug messages.

Dependencies#

If you have followed the steps for the automatic installation, you do not need to worry about installing the dependencies manually.

However, if you followed the manual installation steps, you will need to install:

  • openssl
  • ca-certificates
  • systemctl
  • libcurl4-openssl-dev
