You can restore Amazon S3 general purpose and directory buckets to their original location, to any of the cloud storage systems, to disk, or download to your server.
You can restore data, along with the metadata and ACLs to the original bucket, to a different bucket, or to a new bucket in the same cloud.
You can perform cross-cloud restores of metadata to Azure Blob, see Cross-Cloud Restores of Metadata Between Amazon S3 and Azure Blob.
