15 open source backup solutions to protect your data in 2026

Discover command-line tools, desktop solutions, and enterprise systems that keep your data secure and recoverable.

Protecting your data has never been more crucial. With the rise of hybrid work, cloud-native applications, and ransomware threats, reliable backup solutions are indispensable for individuals and organizations alike. Open source tools have emerged as leaders in this domain, offering transparency, flexibility, and community-driven innovation.

Whether you need a lightweight tool for personal files or a robust system to protect enterprise networks, the fifteen open source backup solutions highlighted here provide reliable options for almost every scenario. Each brings its own strengths, from encryption and deduplication to cloud integration and cross-platform support.

Command-line and server solutions

Amanda is a backup system written in C and Perl that allows a system administrator to back up an entire network of client machines to a single server using tape, disk, or cloud-based systems. It was developed and copyrighted in 1991 at the University of Maryland and has a BSD-style license. Amanda remains a solid choice for enterprise network backups.

BackupPC is a high-performance, enterprise-grade system for backing up Linux, Windows, and macOS PCs and laptops to a server’s disk. It is licensed under the GPLv3 and excels at deduplication, making it efficient for backing up multiple similar systems across a network.

Bacula is a set of open source computer programs that permit you (or the system administrator) to manage backup, recovery, and verification of computer data across a network of computers of different kinds. Bacula has an AGPLv3 license and offers enterprise-grade features for complex backup environments.

BorgBackup is a deduplicating backup solution that features compression and encryption. It is supported on Linux, macOS, and BSD and has a BSD License. The project has excellent documentation and is particularly well-suited for users comfortable with the command line who need efficient, secure backups.

Rclone is a command-line program to manage files on cloud storage. It is a feature-rich alternative to cloud vendors’ web storage interfaces. Over 70 cloud storage products support Rclone, including S3 object stores, business and consumer file storage services, as well as standard transfer protocols. Rclone has an MIT license, supports Linux, macOS, and Windows, and is easy to download and install. 

Restic is a backup program that is fast, efficient, and secure. It supports the three major operating systems and has a 2-Clause BSD license. Its code is available on GitHub and the project has excellent documentation. Restic’s simplicity and reliability make it a popular choice for both personal and professional use.

Desktop and user-friendly tools

Back In Time is a simple backup utility designed for Linux. It provides a command-line client and a GUI, both written in Python. To do a backup, just specify where to store snapshots, what folders to back up, and the frequency of the backups. Back In Time is licensed with GPLv2 and offers straightforward scheduling for personal backups.

Cronopete is a Time Machine-like backup for Linux. The project provides packages for rpm and Debian-based systems. You can choose to build it from source if you need a different solution. It has a GPL v3 license and brings macOS-style backup simplicity to Linux users.

Déjà Dup is a user-friendly backup tool that takes the hassle out of doing backups the right way. It runs on top of Restic, giving you strong encryption, off-site options, and reliable scheduling, all without the complexity. Using Déjà Dup you can backup your files to Google Drive, Microsoft OneDrive, network servers, or a local folder. It’s an excellent choice for users who want Restic’s power with a simpler interface.

Duplicati is a free backup solution that works on Windows, macOS, and Linux with a variety of standard protocols, such as FTP, SSH, and WebDAV, as well as cloud services. It features strong encryption and has an MIT license. The user-friendly interface makes it accessible for less technical users.

Kup is a backup scheduler for the Plasma desktop. Kup is created for helping people to keep up-to-date backups of their personal files. Connecting a USB hard drive is the primary supported way to store files, but saving files to a server over a network connection is also possible for advanced users. It integrates seamlessly with KDE environments.

Timeshift is a backup utility for Linux that is similar to System Restore for Windows and Time Machine for macOS. Timeshift protects your system by taking incremental snapshots of the file system at regular intervals. These snapshots can be restored at a later date to undo all changes to the system. It’s particularly useful for system recovery rather than personal file backup.

urBackup does full and incremental image and file backups. You can save whole partitions or single directories. It has clients for Windows, Linux, and macOS and has a GNU Affero Public License. The project maintains good documentation and offers both a server-client architecture and ease of use.

Modern alternatives with advanced features

Kopia has emerged as a powerful alternative to Borg, with a modern UI and cloud integrations. It is a versatile backup solution for Windows, macOS, and Linux that delivers fast incremental backups with built-in compression, data deduplication, and secure end-to-end encryption. Available with both a command-line interface and an easy-to-use graphical interface, it has an Apache 2.0 license. Kopia represents the new generation of backup tools with both power and accessibility.

Syncthing synchronizes files between two computers. It is licensed with the Mozilla Public License and is secure and private. It works on macOS, Windows, Linux, FreeBSD, Solaris, and OpenBSD. It is easy to download and the project provides good documentation. While primarily a sync tool rather than a traditional backup solution, Syncthing excels at keeping files consistent across multiple devices.

Choosing the right solution

The backup landscape offers options for every need and technical comfort level. Command-line tools like BorgBackup and Restic provide power and efficiency for technical users. Desktop solutions like Déjà Dup and Duplicati make backups accessible to everyone. Enterprise systems like Bacula and BackupPC handle complex network environments. Modern tools like Kopia bridge the gap with both GUI and CLI options.

By adopting one of these tools, individuals and organizations alike can ensure their data remains secure, recoverable, and resilient against evolving challenges. The key is choosing a solution that matches your technical expertise, backup requirements, and infrastructure, then implementing it consistently. Your data’s safety depends not just on having a backup tool, but on using it regularly and testing your restores.
