Configuring Borgmatic: Step-by-Step Guide

1. Create the configuration directory

sudo mkdir -p /etc/borgmatic

2. Generate a sample configuration file

sudo borgmatic config generate

For versions prior to 1.7.15 use this command instead to generate the configuration:

sudo generate-borgmatic-config

3. Edit the configuration file

sudo nano /etc/borgmatic/config.yaml

Main configurations:

• source_directories: the directories to be backed up
• repositories: paths to the backup
• retention: rules for maintaining and cleaning backups
• encryption_passphrase: encryption password

Example:

location:
    source_directories:
        - /home
    repositories:
        - /mnt/backup-repo
retention:
    keep_daily: 7
    keep_weekly: 4
    keep_monthly: 6

Performing Backup with Borgmatic

To manually start a backup:

sudo borgmatic

To schedule with Cron:

sudo crontab -e

For example, add:

0 2 * * * /usr/local/bin/borgmatic

To restore a Backup with Borgmatic

1. Backup list

sudo borgmatic list

2. Restore files

sudo borgmatic extract --path /home/user/documents

Best Practices for Linux Backups with Borgmatic

• Test your backups regularly.
• Keep backups on different devices.
• Use encryption.
• Document your configuration.
• Monitor the status of your backups.

Backup Strategies and Disaster Recovery Plan

Backup Strategies: the Basis of Data Protection.

An effective backup strategy is not just about randomly saving data. It is critical to plan regular backups, define what data is critical, choose the most suitable destination (local, remote or cloud) and protect backups with encryption systems. With Borgmatic, you can fully automate this process, scheduling daily or weekly backups and setting retention policies to manage space intelligently.

One of the most reliable practices is the 3-2-1 backup strategy: keep at least three copies of data, on two different media, with at least one off-site copy. This approach greatly reduces the risk of total loss, ensuring resilience even in the event of hardware failure or local disasters. Borgmatic can be configured to send backups to both local devices and remote or cloud storage, making it easy to adopt the 3-2-1 strategy.

Create a Comprehensive Disaster Recovery Plan (DRP).

Beyond simple backup, every business-even individual ones-should have a Disaster Recovery Plan (DRP). A good DRP defines what to do in the event of data loss, hardware failure, cyber attack, or natural disaster. Borgmatic integrates seamlessly into a DRP because of its ability to make fast, secure and easily recoverable backups. Having an up-to-date copy of Borgmatic's own configuration is an integral part of an effective recovery plan.

Testing Backup and Disaster Recovery Plan: The Key to Security.

Creating regular backups and having a Disaster Recovery Plan are critical steps, but without practical testing they remain only good intentions. Periodically testing the integrity of backups and simulating full or partial data recovery scenarios is essential. With Borgmatic, you can automate integrity tests via verification commands(borgmatic --verify) and schedule test restores on separate environments. Running regular simulations ensures that backups are actually usable, that staff know how to proceed, and that any problems are detected before a real emergency occurs.
