You can version your files in the S3, it is enabled at the bucket level. Whenever the user upload a file, the S3 is going to create a version of that file at the selected key, same key overwrite will change the version: version 1, version 2, version 3, etc. You can enable versioning under the Properties tab in your S3 console. Note:
- Any file that is not versioned prior to enabling versioning will have version “null”
- Suspending versioning does not delete the previous versions
Why versioning
It is best practice to version your buckets:
- Protect against unintended deletes (ability to restore a version)
- Roll back to a previous version
