The support team at skysync are very helpful, friendly people who genuinely care about their customers success with each product they use from this software suite to its full extent! I have used many different types of sync tools over my career but none as good or reliable than skysync for backing up data across multiple platforms/devices in house - office desktop pc's mobile phones laptops tablets etc all backed by one central cloud server which syncs instantly using various backup methods (local backups via nas drives rdiff-backups cifs shares ftp p2v sh filezilla).
