Use stop-on-error with s3cmd in backup/restore
By default s3cmd continues transfers when it hits an error: https://github.com/s3tools/s3cmd/blob/master/README.md#hints
With long transfers in regards to backup/restore this is a waste of time/bandwidth, and often hides the error. Leaving customers wondering why the backup/restore failed even though the output looks like the s3cmd completed.
