Automated Backups to a specific wasabi cloud storage for each server/app.
You actually don't need to develop anything extra for wasabi.
Wasabi is s3 compatible which means it can use the exact same amazon operations and API.
Only thing you need to implement is allow setting different regions and zones for wasabi.
PS: same apply for eg MinIO (self hosted s3 solution), digital ocean object storage, scaleway object storage. They Are all s3 compatible
