AWS Simple Storage Service (S3) support simple versioning mechanism which helps the user/company to store multiple version of the same object. This helps us in the use case, wherein which a file should not be overwritten if the user/company tries to upload the same file again.
1.To enable the versioning mechanism in an existing bucket, the user has to simply enable the option under Properties tab of the bucket. as shown in the below image.
2. AWS also allows the user to specify the versioning capability at the time of S3 bucket creation.
