I am thinking about buying a 2nd Passport so I have another chance if I need an older document no longer on my hard drive, and if my Passport goes bad. I would plan on connecting them to my computer on different days, but want to know if Smartware will know that file-a has been backed up on on passport1, but not on passport2.
In that case I would want it to copy it to passport2 the next time passport2it is connected, but would not want it to copy it again to passport1 a few days later, unless the file on the hard drive is newer than the one on passport1.
Has anyone tried this?
