Backupninja is a backup tool for Linux systems that allows you to automate the backup process for your data. It can back up your files, directories, MySQL or PostgreSQL databases, and more. In this tutorial, we will learn how to install Backupninja on Arch Linux.
Before we begin, ensure that you have the following:
Backupninja requires several packages to function properly. Open the terminal window and run the following command to install these packages:
sudo pacman -S backupninja rsync duplicity
After the installation is complete, it's time to configure Backupninja to perform backup operations. The configuration file is located at /etc/backupninja.conf. You can modify the configuration file using your favorite text editor.
The following is an example configuration file:
# Example configuration file for backupninja
# For more information, see: https://0xacab.org/liberate/backupninja
# Backup all directories found in /home directory except junk directory twice a day
# to the remote host using rsync.
backupdir "/home/* --exclude /home/junk" {
runcron daily
# Remote backup via rsync
rsync host.example.com:/backup/
}
# Backup specified PostgreSQL database
# to the local directory once a day.
excpgsql "/usr/bin/pg_dumpall -U postgres -f /backup/db.sql" {
runcron daily
}
# Backup specified MySQL database
# to the local directory once a day.
excmysql "/usr/bin/mysqldump -u root -pPASSWORD db > /backup/db.sql" {
runcron daily
}
In this example, we are backing up all files in the /home directory except for the junk directory. The backup is done twice a day, and the backups are sent to a remote host using rsync.
Similarly, we also have two examples for PostgreSQL and MySQL backups.
Once you have made the configuration changes, save the file.
After configuring Backupninja, test it out by running the following command:
sudo backupninja --debug --now
This command will execute your backups immediately and show debugging information while doing so. If there are any issues, you can use the output to troubleshoot problems.
In this tutorial, we learned how to install Backupninja and configure it to automate backup operations on Arch Linux. Backupninja is an excellent tool for automating backups, and with the help of this tutorial, you can now use it to safeguard your data.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
