Idea: Integration of Cloudberry Backup with Cloudberry Command Center

Propose a new feature to integrate Cloudberry Backup with a future Cloudberry Command Center, enabling centralized monitoring and management of backup operations. Currently, there is no official Command Center, but we plan to develop one based on https://github.com/open-gpdb/yagpcc.

Integrating backup with the Command Center would greatly enhance the user experience, eliminating the need to monitor backups through separate tools.

No file, test, or entry point is named. Start by reviewing the existing backup utility and the proposed yagpcc project to define the integration boundary, monitoring and management requirements, and a concrete acceptance plan before implementation.
