Migration to Amazon S3 - How do I know?

I have set up my server to start migration to Amazon S3.
The cron task has ran 3 times so far.
I see success messages:

[{"status":"200","contents":"Emails dispatched successfully","time":"2016-01-04 20:12:32"},{"status":"200","contents":"No cached images to upload to remote storage","time":"2016-01-04 20:12:32"},{"status":"200","contents":"No photos to upload to remote storage","time":"2016-01-04 20:12:32"},

{"status":"200","contents":"50 avatars uploaded to remote storage","time":"2016-01-04 20:12:32"},



{"status":"200","contents":"Nothing to process for files","time":"2016-01-04 20:12:32"},{"status":"200","contents":"Stream items archived successfully","time":"2016-01-04 20:12:32"}]

I do not see a bucket or files on the S3 Console. How can I verify that this is happening correctly?
