Title: Save Database Backups in Cloud Infrastructure

Description:
Implement functionality to save database backups to cloud storage. The feature should:

1. Support uploading backup files to cloud storage services (e.g., AWS S3, Google Cloud Storage, Azure Blob Storage).
2. Provide configuration options for specifying the cloud provider, credentials, storage bucket/container, and backup file path.
3. Include basic error handling for failed uploads.
4. Ensure backups are secure during transfer (e.g., using HTTPS) and at rest (e.g., using encryption).

This functionality will ensure reliable and scalable storage for database backups.
