Backup or Export Rekognition face collection

Yes, you can manage your Amazon Rekognition face collections, though there isn't a direct "export" or "backup" feature specifically designed for collections.

For your concern about data resiliency, there are a few approaches you can consider:

1. Store your original images in an S3 bucket: This is a best practice that would allow you to rebuild your collection if needed. Since you mentioned most examples use S3 buckets, this would provide the resiliency you're looking for.

2. Use the ListFaces operation: This allows you to retrieve information about the faces stored in your collection, including their face IDs. While this doesn't export the actual face vectors, it gives you a record of what faces are in your collection.

3. For collection management, you can use:

• ListCollections: To view all your collections
• DeleteFaces: To remove specific faces from a collection if needed

Unfortunately, there isn't a direct way to copy or duplicate a collection from one to another. If you need to create a backup or copy of your collection, you would need to:

1. Create a new collection
2. Re-index all the original images into the new collection

This is why storing your original images in S3 is particularly important for your use case - it would allow you to rebuild your collection if necessary.

For your WordPress plugin implementation, consider modifying your approach to store references to the images in S3 alongside your face indexing process to ensure you have the ability to recover if needed.
