Amazon S3 Multi-Part Upload and Large Object Support

Amazon S3 storage now supports multi-part uploads and large objects (to rearrange the words in the title slightly).

What does this mean?

Put simply, large files that are backed up to S3 storage can be split into chunks for easier and more reliable uploading. Any chunks that fail to upload can be re-tried individually, instead of the whole file being sent again. Splitting the file into chunks also squeezes a bit more performance out of you bandwith as well.

Large object support increases the maximum size of a file that can be stored on S3 to 5 terrabytes. Which is "quite a lot".
