I've always used Allway Sync to provide real time Back Up of my devices Files to my NAS....... Though I also do a separate Daily Image on all our devices, I like the ability that every file is immediately viewable on the NAS when needed... i.e. not compressed so they can be readily viewed. Unfortunately Allway Sync is not cooperating lately and I'm looking for an alternative. Are any of Synology's APPS a drop in replacement that provides File Sync I can utilize?
