Delta sync is supposed to be live now, for desktop clients, right?
I use 2.5.1 under windows 7 and 8 right now for syncing data logger files from field computers with a central computer. The field computers are connected via 3G/4G which brings bandwidth limits. The files I’m syncing (custom CSV format, TOA5, file extension DAT) per site are ~6-8MB in size and get a line added every half hour, all day long.
So currently I am seeing ~300MB traffic each day, which is complete file syncing and not delta syncing.
What do I miss?
 totally forgot, the server side is being managed by AARNET with a cloudstor server implementation I guess
