Bucardo is an asynchronous PostgreSQL replication system, allowing for multi-source, multi-target operations. It was developed at Backcountry by Jon Jensen and Greg Sabino Mullane of End Point Corporation, and is now in use at many other organizations. Bucardo is free and open source software released under the BSD license.

Three Bucardo mailing lists are available:

  • Bucardo-announce: This is a low volume list used for notices of new versions, important bugs, and security warnings. It is highly recommended that anyone using Bucardo subscribe to this list.

Bucardo users have real-time chat in the #bucardo IRC channel on Libera Chat but the Bucardo-general mailing list tends to be a better venue for questions because it allows for more detailed descriptions and is seen by more people.

We track bugs for Bucardo at GitHub.

git clone git@github.com:bucardo/dbixsafe.git
git clone git@github.com:bucardo/bucardo_org.git
