How to quickly copy an AWS S3 bucket to your local hard drive (without FTP):

aws s3 sync s3://mybucket .

---

The Problem

Using FTP to backup a large S3 bucket is slow. That's because FTP creates a new request for each file, downloads the file, and closes the request. That adds a lot of time to your download.

# Here we use tap to set the post factory's author (since Factory Girl doesn't create singleton instances).
# Using tap passes a block where you can "tap" into the object.
# At the end of the block, the object is returned.
