  2. Enter the following line of command into the blank Notepad file: aws s3 sync "C://Desktop/backups/" s3://your-bucket
  3. Press the CTRL + S and save the file with the .BAT extension.
  4. Next, click on the Start Menu button and search for the task scheduler.
  5. Open Task Scheduler. (If it fails to open, fix it with this guide)
  6. Click on the Actions menu, choose to Create Task, edit the Name, and describe the new task.

  8. Click on the Actions tab and Create basic task from the resulting dropdown menu.

After uploading the parts, Amazon S3 combines the elements into a single file. This multipart upload will result in faster uploads and lower chances of failure with large files.
