Handling deleted files from AWS S3 buckets #2482
Description
When resending files to AWS S3 through PhysioNet, the deleted files on the server aren't deleted from S3 buckets with the current re-upload functionality (i.e., #2289).
We need to implement a way of deleting the files from the S3 bucket to sync its content with the content of the server.
In the meantime, we can potentially use the CLI command on the server as follows:
aws s3 sync --delete
which does mirroring (i.e., "it creates a precise replica of the source in the destination, including the removal of items that no longer exist in the source.").
