I'm looking to backup a drive to an S3 bucket from a script on a Windows machine. I wondered if I could use Cyberduck's CLI to synchronize folders to S3, using the 'upload' option (of Cybduck's synchronize method).
I can execute it from a command line, but it's interactive (I'm required to tell it what to do about files it finds already in the bucket).
Use the --existing and --assumeyes flags.
