What you are doing, as you can tell, won't work. It's NOT file based, but computer based. For example, I have FTM2012 and FTMM-2 (Windows / Mac). I can NOT use the TreeSync feature from both. Expand that to the Back Up's that you were discussing. Does that help? Russ Important Note: The author of this message may not be subscribed to this list.
