I've been using GoodSync to backup data for a number of years. I use a two-way sync so that the two drives I copy back and forth contain the same data.
I've noticed that periodically GoodSync's backup space estimate goes way up in my target drive. When I check what it wants it to sync, I see a list of basically the majority of my files. I've noticed this happen with portable hard drives, and today, for the first time in a portable Samsung Shield rugged SSD.
I used to believe that it was some kind of break down in the hard drives themselves, but now I'm not sure, since the SSDs have never given me trouble before.
Has anyone else experienced this? Is there a setting that maybe I'm not using correctly that is somehow making GoodSync "refresh" the data?
Thanks.
