Exactly what I was looking for! ! !
I downloaded SyncBack Free three days ago and it was exactly what I was looking for. Setting it up was intuitively obvious. As usual I did not read any of the instructions and the pages guided me through the steps. Even provided the needed network address for my NAS. The next day I purchased and installed the SyncBackSE on my Desktop and SyncBack Touch on my laptop. Only trouble I had was I did not use the drop down on the on the first selection screen on the first attempt to set up the SyncBack Touch profile for SBSE. All works great now. Exactly what I was looking for! ! ! I found he instructions and the linked instructions, which are part of the online instruction book, were great and very easy to follow I use it for backing up several thousands of photos taken over fifty years, and my Ham Radio logbook with the record of well over two thousand contacts over 50 years. About ten years, a power outage caused the PC to shutdown and All photos and the Logbook were lost. Since then I make sure my important data is well preserved. This program should do that for you. It can save your data on an inexpensive NAS forever for less than the cost of a year’s storage time in the “Cloud” and only you have the data.
