Bareos: A Sustainable Backup Solution

When discussing backup solutions, environmental impact might not be the first thing that comes to mind. However, with data centers playing a crucial role in our digital infrastructure, it’s essential to recognize their significant environmental footprint. Datacenters contribute substantially to global energy consumption and carbon emissions, making sustainable practices in data management more critical than ever.

The Environmental Impact of Data Centers

Data centers are energy-intensive facilities, consuming about 1% of the world’s electricity and generating a similar proportion of CO2 emissions. As our reliance on digital infrastructure grows, so does the need for sustainable practices.

The Guide to Data Backup Strategies for Businesses

The Guide to Data Backup Strategies for Businesses

In today’s digital age, data is the lifeblood of any business. Whether it’s customer information, financial records, or proprietary data, losing this information can be catastrophic. Implementing a robust data backup strategy is essential to safeguard your business against data loss, damage, and cyber threats. This guide will walk you through the key components of an effective backup strategy, with practical tips and insights to help you protect your critical data.

Basic Information About Backups

When it comes to backing up data, understanding the different types of backups is crucial.

Different Types of Backups

The three main types are full, incremental, and differential backups:

  • Full Backup: This is a complete copy of all your data. While it provides the most comprehensive protection, it is time-consuming and requires significant storage space.
  • Incremental Backup: This type of backup only copies data that has changed since the last backup of any type (full or incremental). It’s faster and uses less storage but can be slower to restore, as it may require multiple incremental backups to be restored in sequence.
  • Differential Backup: Similar to incremental, but it copies all data changed since the last full backup. It strikes a balance between speed and storage usage, and restoration is faster compared to incremental backups since only the last full backup and the latest differential backup are needed.

On-Site vs. Off-Site Backups

Deciding where to store your backups is another critical aspect of your strategy. You can choose between on-site and off-site backups, or a combination of both:

  • On-Site Backups: These are stored locally, on the same premises as your primary data. They offer quick access and recovery times but are vulnerable to physical damage, theft, and local disasters.
  • Off-Site Backups: These are stored in a different location, often in the cloud. They provide protection against local disasters and physical damage but may have slower recovery times and can incur additional costs. A hybrid approach, utilizing both on-site and off-site backups, is often the most effective strategy.
    For instance, Bareos, an open-source backup solution, supports both local and remote backups, giving you flexibility and comprehensive protection.

Best Practices for Backup Strategies

Choosing the Right Backup Software and Hardware

Selecting the right tools is crucial for implementing an efficient backup strategy. Your choice of backup software should align with your business needs, offering features like automation, scalability, and ease of use.

Bareos (Backup Archiving Recovery Open Sourced) is a robust option for businesses of all sizes. It supports a wide range of operating systems and can be tailored to fit various backup needs. Compared to other solutions, Bareos stands out for its flexibility, extensive features, and security, as it’s open-source.

Having enough storage capacity and choosing reliable storage media is essential for an effective backup strategy. Here are some popular options:

  • Local Disk Array: Fast and reliable first stage storage, allowing quick backup and restore
  • Tape: Reliable and secure storage as it allows air-gapping, lowest cost per Terabyte
  • Cloud Storage: Offers off-site redundancy and scalability for added protection.

Each option has its benefits, and using a combination of them can offer robust data protection. Additionally, the type of data you need to back up (e.g., large files vs. billions of small files) will influence your choice of hardware and database design. Bareos allows you to customize its setup to optimize for different data types. Common in large enterprises, these solutions offer high performance, reliability, and scalability for handling large volumes of data efficiently.

Automating and Scheduling Backups

Automating your backup processes ensures that your data is regularly protected without manual intervention. Here are some best practices:

  • Frequency: Determine how often backups should be performed based on how frequently your data changes. For most businesses, daily backups are a minimum requirement.
  • Scheduling: Schedule backups during off-peak hours to minimize the impact on your system performance.
  • Retention Policies: Establish how long you need to retain backups. This will depend on your storage capacity and regulatory requirements.

Bareos offers advanced scheduling features, allowing you to automate backups and manage retention policies effectively.

Implementing the 3-2-1 Backup Strategy

One of the most reliable backup strategies is the 3-2-1 rule:

  • 3 Copies of Your Data: One primary and two backups.
  • 2 Different Storage Types: Such as local drives and cloud storage.
  • 1 Off-Site Copy: To protect against local disasters.

This strategy ensures data redundancy and increases the chances of full recovery. Using technologies like tape libraries and robots can create an airgap, adding an extra layer of security against cyber threats.

Security Measures for Backup Protection

Air-Gapping Your Backups

Air-gapping is a security measure that physically isolates a copy of your data from the network, making it inaccessible to hackers and ransomware attacks. This technique involves creating an offline copy of your backups that is not connected to any network, thus providing an “air gap.” Air-gapped backups are often stored on removable media such as tape drives or external hard drives, which can be disconnected and stored securely. This approach ensures that even if your network is compromised, your critical data remains protected.

Regular Testing of Backup Integrity

It’s not enough to just create backups; you must also ensure they are reliable and can be restored when needed. Regularly test your backups by performing trial restorations. This helps you verify the integrity of your backups and ensures that your data can be recovered in case of an emergency.

Recovering from Data Loss

A disaster recovery plan (DRP) outlines the steps your business will take to recover from a catastrophic event. It should include:

  • Risk Assessment: Identify potential threats to your data.
  • Recovery Objectives: Define your Recovery Time Objective (RTO) and Recovery Point Objective (RPO). RTO is the maximum acceptable amount of time to restore a system after a disaster, while RPO is the maximum acceptable amount of data loss measured in time.
  • Backup and Restoration Procedures: Detailed instructions on how to restore data from backups.
  • Communication Plan: Procedures for communicating with employees, customers, and stakeholders during a disaster.

Bareos provides features that support the creation and execution of a robust DRP, ensuring rapid data recovery and minimal downtime.


Implementing a comprehensive data backup strategy is vital for protecting your business against data loss. By understanding the different types of backups, choosing the right storage solutions, and following best practices for scheduling and testing, you can ensure your data is always safe. Solutions like Bareos provide robust and flexible options to meet your backup needs, helping you build a resilient data protection strategy.

Github Issues replaces Mantis

The Bareos project will use GitHub Issues (instead of Mantis).

In 2012, the Bareos project was launched with a commitment to fostering close integration with the community and leveraging advanced automation services. However, a span of 10 years provides ample opportunity for evolution and innovation. Over the course of this decade, we have continuously adapted and modernized our infrastructure.

Among other changes, we have made significant advancements in the following areas:

Since the beginning, we have relied on git and GitHub as our code repository. Initially, we accepted contributions in the form of emails and patches. However, for some time now, we have exclusively transitioned to using Pull Requests, automated tests, and a structured review process.

Package Building:
Originally, our package building process relied heavily on the powerful for Linux packages. However, we had to resort to different approaches for other platforms. Therefore we have transitioned to using Jenkins, Build-Worker, and Docker containers for all platforms. This transition has been seamless for end-users, but it allows us to create packages for all our platforms within the same streamlined process. Additionally, this optimized process tailored for Bareos operates much faster.

Since our inception in 2012, we have utilized Mantis as our bug tracker, and for the most part, we were satisfied with its performance. However, due to a tighter integration with our other processes, we have decided to migrate to Github Issues in April 2024. We anticipate that this transition will result in a better integration of error reporting, development, and pull requests.

In addition to our internal processes, we utilize as a ticketing system for customers with support contracts.

Ransomware Protection: How to Safeguard Your Data with Advanced Backup Solutions

Discover essential strategies for ransomware protection. Learn how Bareos backup solutions fortify your defenses against digital threats, ensuring your data’s security and accessibility.

In an era dominated by digital threats, ransomware emerges as a formidable adversary. This malicious software encrypts your files, effectively holding them hostage until a ransom is fulfilled. The threat it poses to both individuals and organizations is profound. Yet, the battle is not lost. Armed with the right strategies and tools like Bareos, securing your valuable data against ransomware is within reach. Ransomware encrypts the victim’s files, rendering them inaccessible. The perpetrators then demand a ransom for data restoration. It commonly infiltrates systems through phishing emails, malicious websites, and software vulnerabilities.

Essential Ransomware Protection Strategies:

1. Cybersecurity Awareness: Empower your team with the knowledge to identify phishing attempts and malicious links. Regular cybersecurity training enhances your first line of defense.

2. Advanced Security Software: Deploy security solutions encompassing antivirus, anti-malware, and firewall protections to destroy ransomware attempts.

3. Reliable Backups: Keep updated backups of critical data. Bareos backup solutions provide automated, secure backups that are pivotal for business continuity post-ransomware.

4. Software Updates: Ransomware exploits outdated software. Consistently updating your systems and applications fortifies your defenses.

5. Access Control: Limit access to essential data, applying the principle of least privilege to reduce risk.

6. Disaster Recovery Planning: A disaster recovery plan is indispensable. It should detail response actions for ransomware incidents, including data isolation and restoration.

7. Network Segmentation: Dividing your network limits ransomware spread, safeguarding sensitive data across various segments.

8. Email Security: Implement email filtering to eliminate phishing threats, a primary ransomware conduit.

Among all strategies for combating ransomware, regular backup is paramount. It is the only method that guarantees data recovery after an attack. Other preventative measures aim to block attacks, but they do not guarantee data recovery in the event of a breach. Regular, secure backups, using solutions like Bareos, safeguard your data by preserving it in its pre-attack state and making it recoverable in all scenarios. This not only enhances your defense, but also effectively renders ransomware demands ineffective, demonstrating backups as the ultimate defense in your data protection strategy.

Enhance security by hardening the Bareos filedaemon

The Bareos filedaemon (client) runs per default with administrator/root privileges in order to be able to backup all files. The Filedaemon also is able to execute scripts before and after the backups and restores. In order to perform restores, the filedaemon has the ability to overwrite all files on the client machine. While all of this is required for normal backup and restore operation, certain environments might have higher security requirements.
Bareos offers the following options are available to enhance the security and limit the power of the filedaemon:

Favicon für den Browser
  • Limit the directories from where the filedaemon executes scripts. This can be achieved with the configuration directive Allowed Script Dir
  • Limit the Job Commands that the filedaemon accepts. The Allowed Job Command directive determines which of the existing job commands (backup, restore, verify, estimate and runscript) are allowed. By prohibiting the restore command, the filedaemon will not allow to do restores. Without the runscript command, no runscripts will be executed.
  • run the filedaemon as non-root user with the capabilities CAP_DAC_READ_SEARCH. This uses the Linux capabilities mechanism to run as normal user but have the the right to read all files. Writing files will not be possible in this setup.

These security measures can prevent an attacker that gained control over the bareos director to alter the files of the machines being backed up.
However, when a restore is required, the filedaemon on the client needs to be reconfigured to allow restores and/or runscripts. Alternatively, a second bareos filedaemon can be started that has a configuration that allows restores.

Usually the amount of restores is much smaller than the backups, so these measures still can enhance the security with relatively little effort and inconvenience.

SILL List 2023: Bareos once again on French reference List

Import and export tapes from your tape library with Bareos

Tape libraries usually offer an option to insert and remove tape cartridges. Therefore, the libraries have a number of dedicated slots (so called import/export slots or mail slots) that can be accessed from outside of the library without the danger of the operator to collide with the tape robot. Bareos supports this functionality with the bconsole commands import and export commands:

  • To import tapes into the library, just fill the import/export slots with the tapes and type import.
  • To export tapes from the library, use export volume=<volumename>
  • Tapes used by a job can be automatically exported with use of a runscript

For more details, please check the bconsole documentation about import and export console commands.
