I want to set up folders on a couple of machines where any added content is uploaded to a specific Google Drive location. But I only want files to be added - if I remove files from that folder on the computer, they should still be available in Google Drive. (one way sync, or "additive" sync)
This is very useful for building a large photo library with pictures from multiple sources/machines that has limited disk space.
Is this possible with insync or is it only capable of standard two way sync?
