I always felt concerned that Windows, being so much more universal on the world's desktops, could be so lacking in that respect.
What's most surprising about this is the lack of interest. With the increasing popularity of flash media that has almost unlimited (and generally much faster) read speed with a life limited by disk writes, it seems like a very strange blind spot.
At least we have one more solution now -- not entirely free, but better than nothing...
did you ever check TimeDicer ... there seems to be a SyncBreeze
Thanks for the suggestions ... will try to look into these along with the Bvckup 2 beta.
