如何使用 lambda javascript/node.js 将新的 s3 对象同步到其他 s3 帐户

Question

I'm using aws-sdk and lambda with javascript.

using this listObjectV2 and copyObject, I'm able to copy the objects from the other account, but I think this s3.copyObject, copy ALL the objects including new objects.

I just want to copy/transfer file only for new and updated objects. Its like the cli the aws sync.
