Is there a another automated way of syncing two Amazon S3 bucket besides using s3cmd? Maybe Amazon has this as an option? The environment is linux, and every day I would like to sync new & deleted files to another bucket. I hate the thought of keeping all eggs in one basket.
You could use the standard Amazon CLI to make the sync. You just have to do something like:
aws s3 sync s3://bucket1/folder1 s3://bucket2/folder2
