Keep your data safe with the help of backup software.

From cyberattacks, viruses, and hard drive crashes to accidents such as water spills on computers or laptops—anything can lead to months and years worth of data getting erased. Irrespective of your business role, you certainly wouldn’t want such a setback. Fortunately, there are many backup software solutions to help you prevent data loss incidents.

If you’re looking for a backup tool that can be customized to your specific data needs, then open source software is your answer. Software developers on your team can tweak the software code per your requirements and build a whole new product that caters better to your specific needs.

To help you make the right choice, we’ve compiled a list of the three best open source backup software (listed alphabetically) based on user ratings and reviews. (Read how we selected these products.)

1. EaseUS Todo Backup: Allows rebranding of the application

EaseUS Todo Backup is a backup and restoring software tool that creates a backup of your system data every day. It helps recover deleted files or files that you may have lost due to unexpected crashes, thefts, or ransomware.

2. IDrive: Offers shipment of physical storage devices

IDrive is cloud backup software that lets you create a backup of your desktops, laptops, and mobiles. This backup solution can also create data backup from an external drive. Its online file sync feature syncs files across devices in real time, allowing you to access the latest versions of files from any linked device.

None of the data is deleted from your online account unless you manually clear the archive. Also, your backup data is encrypted with 256-bit AES to prevent thefts or unauthorized access.

IDrive offers shipment of physical storage devices for data backup and retrieval. You simply transfer your data to a temporary storage device using IDrive’s local backup option and ship the device back to the service team. You can then continue with incremental backup. Once the team receives the device, it will transfer the data to your primary storage device. In case data retrieval is needed, the team will ship the temporary storage device to you with the most recent version of your backup files.

IDrive’s support options include call and online assistance (via forms). Open source codes are available for some IDrive applications under the GNU General Public License, which allows you to change and share the software apps.

3. Storj: Comes with decentralized cloud storage

Storj is a backup software tool that offers decentralized cloud storage. Unlike centralized cloud storage where all the data is stored in one large data center, Storj encrypts all the files, splits them into 80 pieces, and stores them onto a global network of storage nodes. To reconstitute a file, only 29 of the 80 pieces are required. This means you can retrieve the stored files from any location, at any time.

Storj prevents data breaches, malicious attacks, and unauthorized access by using AES-256-GCM symmetric encryption. Its automatically generated encryption keys help control data access so only you or those you grant permission to can access the data.

You have an option to integrate the software with developer tools, apps, and services, including Fastly, Node dashboard, and Android bindings.

Storj’s support options include a community forum and FAQs. Developers can join Storj’s open source project to increase networking and improve the software.

How to choose the right open source backup software

Before you make up your mind, here are some points to consider to find the right open source backup software:

  • Open source licensing: It’s a misconception that open source software is free to use, customize, sell, and deploy. These software solutions are classified under various licenses such as the General Public License, Lesser General Public License, and Affero General Public License. Before selecting open source backup software for your needs, understand its license classification and the obligations it carries.
  • Skillset to develop the code: Different open source backup tools have different numbers of features and functionality, resulting in complex codes. But your developers may not have the skill set to work on those codes, and additional training may be required. Therefore, look for a tool that works well with the current skill set of your team, and check if training your team will help fulfill future requirements.
  • Types of documentation: There are two types of open source software documentation: user documentation and developer documentation. User documentation generally describes how to use the system, while developer documentation describes how to add and change the code. The availability of these documentation types gives a sound idea of the quality and support you will get with the selected open source backup software.

Common questions to ask while selecting open source backup software

You’ll find what you’re looking for when you know what to ask. Here are a few questions you should ask vendors while evaluating software:

How secure is your software?

Security is one of the crucial aspects of developing software. Your developers can find vulnerabilities in the open source backup software and fix them. However, it’s still a good idea to go for a backup solution that already offers a good level of security so your developers can focus on other software elements. Therefore, ask vendors about the security and data protection measures their solutions offer and what are the possible ways to improve them.

What are the available support options?

If you’re ever stuck with any technical difficulty, you should know how and whom to reach out to. That’s why it’s important to have quality support. Open source backup solutions usually come with community support or public groups and forums where you can ask and answer questions. Another support option is third-party paid support. This option is for support issues that cannot be solved by the community.

How compatible is your software?

Compatibility issues are common with open source software. To run the program, you might need specialized hardware and drivers that are only available from the equipment manufacturer. This will quickly increase the cost of adopting the software. Therefore, we suggest that you ask vendors about the compatibility of their products and check whether your hardware supports them.

How did we choose these products? We didn’t—you did

To find your ideal software match, you need information you can trust—so you can save time, stay on budget, and focus more energy on growing your business. It’s why we vet and verify all our user reviews and recommend only the tools endorsed by people like you.

In other words, our product recommendations are never bought or sold, or based on the opinion of a single individual—they’re chosen by your peers, reflecting the views and experiences of our independent base of software reviewers.

At Capterra, we objectively select and rank products based on a methodology developed by our research team. Some vendors pay us when they receive web traffic, but this has no influence on our methodology.

To be considered for this list, products had to:

  1. Have at least 20 unique product reviews published on Capterra within the past two years, with an average rating of 3.0 or higher (as of March 22, 2022). We selected the three products with the highest ratings to feature in this article.
  2. Offer an open source, stand-alone version of the software with the source code freely available that can be modified and redistributed.
  3. Meet our backup software market definition: “Backup software ensures security of critical data by creating redundant copies that can be restored to replace corrupted or lost data.”

“Best functionality” tool is identified based on the highest user ratings for functionality that a vendor received based on publicly available reviews (as of March 22, 2022).

Disclaimer: We conducted this analysis based on reviews and ratings data as of March 22, 2022. In order to present the most up-to-date information, the product cards show real-time ratings. Please note that this means the ratings value in the product card may not reflect the ratings value at the time of analysis.

Product research for this article was conducted by Himanshi Arora.
