I have used this software for so many years and there are not any problems with it. I have not encountered any compatibility problems. No other software could replace it. It has done a great job for me and it is very simple to set up.
What surprises me most is setting scheduling, particularly the monitor feature. When I change a file, it syncs automatically. The changes may delay so you need to wait for a period of time. The list changes from time to time.
The amazing support handles everything for me. The developers are always working hard to make lots of improvement. I have inquired some cloud storage platforms, and they really take this as a good idea and are working on this change. Once this new added feature is done it will become the most appealing backup program I guess!
Best backup and sync solution with the best price.
