It is possible to copy/ multiply files on your gateway like this:
If you have a second server, click bounce on it, then click bounce on your gateway. It also works with any bounce connection.
Upload the file that is to be upgraded to preserve the version. You should now be able to upload the file to your own gateway using the other server(s) as proxy. Upload time depends on your bandwidth.
Are you going to improve it in the future?
Because BW usage just to duplicate a file sucks, don't you think?
Althought, it's already better than nothing! Thanks for implementing it!
