Rsnapshot is a backup utility that allows you to take incremental backups of your filesystem. It is available in the FreeBSD Ports Collection, making installation a breeze. In this tutorial, we will walk you through the steps required to install Rsnapshot on FreeBSD Latest.
Before installing Rsnapshot, you need to ensure that your FreeBSD system is up-to-date with the latest software updates. You can update your system by running the following command as root:
# freebsd-update fetch install
The first step is to install Rsnapshot from the FreeBSD Ports Collection. To do this, run the following command as root:
# cd /usr/ports/sysutils/rsnapshot && make install clean
This command will download the Ports Collection for Rsnapshot and its dependencies, compile the software, and install it on your system.
After installing Rsnapshot, the next step is to configure it to suit your needs. Rsnapshot configuration files are located in the /usr/local/etc/rsnapshot/ directory.
Open the rsnapshot.conf file using your preferred text editor:
# nano /usr/local/etc/rsnapshot.conf
In this file, you can specify the locations on your system that you want to back up, the backup types (e.g., full or incremental), the backup destination (e.g., an external hard drive or remote server), and retention policies.
Make the necessary changes to the rsnapshot.conf file as per your requirements.
Before you start taking backups, it is essential to test your Rsnapshot configuration. Rsnapshot comes with a built-in configuration test tool that you can use to check your configuration for errors.
To test the Rsnapshot configuration, run the following command:
# rsnapshot configtest
This command will check your rsnapshot.conf file for syntax errors, missing parameters, or other configuration issues. If there are any errors, the test tool will provide details on how to fix them.
Once you have tested your Rsnapshot configuration, the next step is to schedule backups. Rsnapshot comes with a sample crontab file located in the /usr/local/etc/rsnapshot/ directory.
Open the rsnapshot.cron file:
# nano /usr/local/etc/rsnapshot.cron
This file contains example crontab entries that you can use to schedule backups at specific times of the day. You can also modify these entries and add your custom backup schedule.
Once you have added the desired entries to the crontab file, save and exit the file.
After configuring and scheduling the backups, you can run the first backup manually to ensure that everything is working correctly. To take a manual backup, run the following command as root:
# rsnapshot -c /usr/local/etc/rsnapshot.conf hourly
This command will take a backup of all the directories and files specified in the rsnapshot.conf file.
In this tutorial, we walked you through the steps required to install Rsnapshot on FreeBSD Latest, configure it, schedule backups, and run backups manually. By following the steps in this tutorial, you should now be able to use Rsnapshot to take incremental backups of your filesystem.
