UrBackup is a free, open-source backup system combining image and file backups with fast restore. See its features, licensing, and how it compares.
UrBackup is a free, open-source backup system built around a client-server architecture, created by developer Martin Raiber with the project active since roughly 2011. It combines full image backups with continuous incremental file backups so that both bare-metal recovery and quick file-level restores are possible from the same system.
The software is distributed under the AGPLv3+ open-source license, so anyone can install, use, and modify it, including for commercial purposes, without paying license fees. It runs across Windows, Linux, macOS, FreeBSD, and several NAS platforms.
UrBackup clients continuously monitor watched folders for changes, allowing fast incremental backups without waiting for a scheduled full scan, and can back up files that are actively open, such as email archives. The server provides a web interface for configuring jobs and checking client status, plus deduplication that stores identical files across multiple clients only once.
Restores can be performed through the web interface, the client app, directly via Windows Explorer, or from a bootable USB or CD for full bare-metal system recovery. UrBackup also supports backing up remote and mobile clients over the internet, not just devices on a local network.
UrBackup is entirely free and open source under the AGPLv3+ license, with no paid tiers or per-device licensing costs disclosed publicly. Users are responsible for their own server and client hardware, and community support is available through the project's forums and GitHub issue tracker.
