add only different file to s3 archive

Hello, you can use CLI to make incremental updates to your zip archive. You can use the aws s3 sync command to download the zip archive, make the changes, and then upload only the modified files back to S3. Please refer to this man page https://docs.aws.amazon.com/cli/latest/reference/s3/sync.html

Another way-through, using a versioning feature for your bucket. This allows you to store multiple versions of an object and easily roll back to a previous version if necessary. Check this for more information https://docs.aws.amazon.com/AmazonS3/latest/userguide/Versioning.html

It's important to choose the one that best fits your specific use case and requirements.
