Roadmap Discussion: Future Direction of cloudberry-backup

## Background

As the cloudberry-backup project continues to evolve, we want to ensure that our development priorities align with the community's needs. We've recently integrated **gpbackman** as our open-source backup management tool and are now planning the next phase of development.

## Current Status

cloudberry-backup currently provides:
- **gpbackup** and **gprestore** utilities for backup and restore
- Incremental backup support
- Plugin support (S3, etc.)
- **gpbackman** integration for backup lifecycle management

## We Need Your Input!

We'd love to hear from the community:

1. **Missing Features**: Are there any critical features we've missed that you need for your backup workflows?

2. **Pain Points**: What are the biggest challenges you face with the current backup tools?

Please share your thoughts by:
- Commenting on this issue with your feedback
- Sharing your specific use cases or requirements
- Suggesting additional features or improvements
