I'm here to help too, my username is "retrogamenx". I was trying to compile recalbox-buildroot last night and it's not finishing. Unfortunately I didn't save the log output. I'll try again later on!

I can leave without this, but for sure the feature would add some nice possibilities. I could recompile recalbox to have rclone by default, but I don't know how to deal with Emulationstation programming to integrate it in the UI.

That was only an example, you don't need a NAS to run rclone! Please follow these steps to get rclone running in your recalbox and so have the ability to sync with your Dropbox: 1) SSH your recalbox 2) Download the rclone: # wget http://downloads.rclone.org/rclone-v1.30-linux-arm.zip 3) Unzip: # unzip rclone-v1.30-linux-arm.zip 4) Link the recalbox with Dropbox: # cd rclone-v1.30-linux-arm # ./rclone config e) Edit existing remote n) New remote d) Delete remote s) Set configuration password q) Quit config e/n/d/s/q> n name> remote Type of storage to configure. Choose a number from below, or type in your own value 1 / Amazon Cloud Drive \ "amazon cloud drive" 2 / Amazon S3 (also Dreamhost, Ceph) \ "s3" 3 / Backblaze B2 \ "b2" 4 / Dropbox \ "dropbox" 5 / Google Cloud Storage (this is not Google Drive) \ "google cloud storage" 6 / Google Drive \ "drive" 7 / Hubic \ "hubic" 8 / Local Disk \ "local" 9 / Microsoft OneDrive \ "onedrive" 10 / Openstack Swift (Rackspace Cloud Files, Memset Memstore, OVH) \ "swift" 11 / Yandex Disk \ "yandex" Storage> 4 Dropbox App Key - leave blank normally. app_key> Dropbox App Secret - leave blank normally. app_secret> Remote config Please visit: https://www.dropbox.com/1/oauth2/authorize?client_id=XXXXXXXXXXXXXXX&response_type=code Enter the code: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX -------------------- [remote] app_key = app_secret = token = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX_XXXX_XXXXXXXXXXXXXXXXXXXXXXXXXXXXX -------------------- y) Yes this is OK e) Edit this remote d) Delete this remote y/e/d> y e) Edit existing remote n) New remote d) Delete remote s) Set configuration password q) Quit config e/n/d/s/q> q 5) Test the connection: # ./rclone lsd remote: 6) Follow the rclone documentation for usage: http://rclone.org/docs/

I have used rclone in a D-Link NAS successfully to backup my data to Dropbox. It supports several cloud services, could be an option. http://rclone.org/
