Amazon S3 Put Requests Problem

Hi, What is "Put Requests of Amazon S3" ? i have now 2,138 Requests. why so many? o have only 7 websites. 7 zip files uploaded? all time cpanel uploading one zip file. I don't understand what it means Put Requests. Is there a way to guesstimate the size (and/or compressed size) of the backups? Will it be transferred as individual files, meaning lots of PUTs? Or fewer?
