Code for cloud backup and restore to Amazon S3

I need a Visual C# windows form and code writing. The form should show an explorer view of the local disk drives and allow the user to select the files and folders (checkboxes to each item). Once the files and folders are selected, click an upload/backup button or set a time schedule to upload/copy/backup all the selected items to a predefined Amazon S3 bucket and folder name (based on a unique name to that user and their computer name - "unique-user\their-pc\*all the files and folders*). The file transfer should support large files and use a secure transfer method. I also need the reverse form and code that will read what's in the bucket\folder and display as an explorer view so files can be selected for download/copy/restore back to the computer. The process should only copy files and folders that have changed/don't exist. It should create a log file (txt) on the computer which shows all files and folders copied, number of files, folders, size of selection, success or failure, backup or restore. I will need the code as a Visual SLN file or similar as it needs to interact with other code I have. Please see the pictures for a guide to how this should look. It doesn't have to look 100% like these, but you get the idea! Thank you.
