What Burp is
Burp is free, open-source network backup and restore software released under the AGPLv3 licence. It is designed to reduce network traffic and backup storage use, with self-hosted operation across Linux, macOS, and Windows environments. Unix-based systems can run the server, while clients run on Windows and Unix-based systems. Burp supports delta differencing through librsync, storage deduplication, network rate limiting, scheduled and resumable backups, multiple retention periods, and automatic client upgrades. SSL can encrypt client/server communication, while client-side file encryption is available but disables delta differencing. It handles files, directories, links, permissions, timestamps, ACLs, extended attributes, and Windows EFS files. Email notifications, an ncurses monitor, and the separate Burp-UI provide monitoring and reporting tools. The download page lists versions 3.3.0 and 3.2.0.
