S3 File Upload Settings- Overwrite, Ask, etc.

Question

Good morning everyone! I'm looking for the file upload settings in S3 that will give me the option to overwrite a file when I upload the same file, ask me what to do with the duplicate filing I am uploading, etc. It's like when you try to open a file in some browsers... unless you set up some settings, the dialogue will ask you which application to use, if you always want to use that application, or always ask first. I want to have options when uploading files. Thank you :-)

Answer

There is no such setting in S3 by default, any features like this would be managed by a client. By default, uploads for an object with the same name and key of an existing object to a bucket that is versioned will result in a new version of the object being uploaded. If the bucket is not version, the upload will overwrite the existing object.

Answer

By default, when you upload the file with same name. It will overwrite the existing file. In case you want to have the previous file available, you need to enable versioning in the bucket.

In case any one wants a reference, "Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written"
