研究方向

Implement a backup function in bayeslite using the sqlite3 backup API as referenced in the issue. The implementation depends on issue #92, which should be resolved first. Review the existing SQLite integration in the repository to understand the pattern for adding new operations. Consider looking at the sqlite3 backup API documentation for the required steps and error handling.
