Install BackupPC4 Ubuntu Debian {script}

Install BackupPC4 Debian Ubuntu

The following page outlines how to install BackupPC 4 from the latest official release tarballs or from git. For instructions on building packages, see Build Your Own Packages.

These instructions are tested on Ubuntu Xenial 16.04 LTS and Ubuntu Bionic 18.04 LTS. The script will likely work on other versions and on most other Debian-derived distributions as well.

Installing BackupPC 4 from the latest git sources is a rather long process at the moment. To make it easy, you can use the following script to install a dedicated BackupPC 4 server. The script is tested on a clean installation, so beware of any conflicting web sites if you are not installing on a dedicated server.

The script will use a single password for both your web interface backuppc user and the local backuppc user. It also allows any client to connect, so make sure to tune security settings for a production environment. Run it with root privileges (i.e. sudo bash installbackuppc or chmod 755 installbackuppc && sudo ./installbackuppc if you saved the script as installbackuppc).

Use the same script for updating/ upgrading

Make sure to change the versions to the latest releases:

#!/bin/bash
set -e
bpcver=4.2.1
bpcxsver=0.57

Scroll through the script, know what you are doing.

Uncomment the upgrade section(s) and comment out the install section(s)
