Hi, i tested CloudDrive thanks for another great product. I got question about delta sync. Some providers like Dropbox using delta sync to upload just part of file that actualy change. Does using CloudDrive overcome provider inability to upload only changes or if i change small part of big file it will upload whole file ? I also sugest look on hubic.com it using openstack api http://api.hubic.com/and from my experience is fastes storage for me in EU.
