I was faced with the task of moving about 5GB worth of files from one Amazon S3 bucket to another, both under separate accounts. One of the main challenges, of course, was to not have to download the files to an intermediary location first to only then have to re-upload them to their final destination.

Solution: Bucket Explorer, which support copying (or moving) files between S3 accounts.

It did take 9.5 hours to copy 71,903 files (5.08GB) but it all went smoothly, with only two file copy failures.

I was able to do it all under their 30-days trial license, but I’m thinking I might just buy the product, even if I don’t need it again, as it truly helped me out this time around.
