Boto3: Verify if the file has been uploaded using upload_file()

Question

I\'m making a backup script using boto3 using this line to upload the item:

bucket.upload_file(backup_file_name,bucket_path+backup_file_name)

Answer 1

It will raise boto3.exceptions.S3UploadFailedError. You can also do a head_object request to verify that the object looks like it should. This will raise a botocore.ClientError with the code 404 if the object does not exist.
