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
