How to Install Rsnapshot on macOS

Introduction

Rsnapshot is an open-source backup utility that helps create point-in-time copies of your filesystem. It makes use of the rsync and ssh utilities to transfer and store backups securely. In this tutorial, we will guide you through the installation of Rsnapshot on macOS.

Prerequisites

  • macOS operating system
  • Access to a terminal with administrative privileges
  • Command-line tools installed on macOS

Installation

  1. Open your terminal.

  2. Ensure that your Homebrew package manager is updated to the latest version by running the following command:

brew update
  1. Install Rsnapshot and its dependencies with the following command:
brew install rsnapshot
  1. Wait for the installation to complete.

Configuration

  1. Open the Rsnapshot configuration file in your preferred text editor. The configuration file is located at /usr/local/etc/rsnapshot.conf.

  1. Specify the source and destination directories for your backups. Add the following lines to the configuration file:
backup /path/to/source/dir/ user@hostname:/path/to/destination/dir/

For example, to backup your Documents folder to a remote server with IP 192.168.0.10, add the following line to the configuration file:

backup /Users/yourusername/Documents/ [email protected]:/backups/yourusername/Documents/

  1. Save and exit the configuration file.

  1. If there are no errors, run a backup with the following command:
sudo rsnapshot hourly
