This plugin adds a configuration interface for extra S3-compatible storage endpoints to a widely-used backup plugin. It is designed for users who need to send their site backups to multiple or specialized cloud storage services beyond the default options.

• Custom S3 Destination Management: Add, edit, and remove additional S3 endpoints through a dedicated tab within the backup plugin's settings. Each destination requires a unique identifier, endpoint URL, region, and access credentials.
• Integration with Backup Jobs: Once configured, these custom destinations appear as selectable storage targets when creating or editing backup jobs, allowing for flexible backup distribution.
• Direct Settings Page Integration: The configuration panel is integrated directly into the existing backup plugin's admin area, keeping all backup-related settings in one familiar location.
• Open Source Development: The plugin's source code is publicly available, allowing for community review, contribution, and transparency in its development and security.
