Duckstream is a standalone disaster recovery tool for DuckDB. It runs as a background process and safely replicates changes incrementally to another file or S3. Litestream only communicates with DuckDB through the DuckDB API so it will not corrupt your database.

If you need support or have ideas for improving how this works, make contributions to Litestream, which this is a fork of. Please join the Litestream Slack or visit the GitHub Discussions. Please visit the Litestream web site for installation instructions and documentation.
