You can upload your own data to the "/ryftone/" directory of your Ryft Cloud instance(s) using the "scp" command.
Lets say your data file is called “mydata.json” and it’s stored on your local computer and you are in a ssh instance where your file is stored. You need your IPv4 Public IP address for your destination instance, which looks like "ec2-xx-xx-xx-xx.compute-1.amazonaws.com" where the xx's represent the IP address.
Run this command to copy it from your local computer, to the “/ryftone/” directory of the specified instance:
$ scp -i “<your key pair file>.pem” mydata.json ryftuser@<IPv4 Public IP>:/ryftone/
