ofxRsync

Header-only openFrameworks addon that syncs files or folders to a remote machine with rsync, on a background thread. Optional recursive copy and --delete for extra files at the destination. Fires copyCompleteEvent when it finishes.

ofxRsync rsync;
ofAddListener(rsync.copyCompleteEvent, this, &ofApp::onSynced);
rsync.send("192.168.1.10", "fred", ofToDataPath("renders/"), "/home/fred/renders", true, false);

Needs rsync and ssh on the path and key-based login to the remote. See also ofxSCP.
