This is a mix between two sources:

• http://www.alfielapeter.com/posts/8-transferring-s3-bucket-contents-between-accounts-with-s3cmd
• and http://blog.techopsguru.com/2011/12/s3-bucket-copying-with-multiple-accounts.html

basically the first resource is great but didn't work for me: I had to remove the trailing "/*" in the resource string to make it work. I also noticed that setting the policy on the source bucket was sufficient. In the end these are the exact steps I followed to copy data between two buckets on two accounts

Basically the idea there is:

• we allowe the destination account to read the source bucket (in the console for the source account)
• we log as the destination and start the copy
