UrBackup

UrBackup is a robust, open-source client/server backup system that excels in efficiently backing up multiple computers on a network to a central server. It uses a combination of image and file backups with continuous or scheduled incremental backups, minimizing storage use and network traffic. A standout feature is its ability to create a complete disk image backup while the operating system is running, without needing a pre-boot environment.

The server provides a clean web interface for management and restoration. Ideal for educational institutions, non-profits, and small businesses with a technical administrator who want a centralized, self-hosted backup solution at zero software cost. It compares to commercial solutions like Veeam by offering similar centralized image and file backup for free, but it lacks the polish, extensive ecosystem, and professional support of its commercial counterparts.
