Didn't work for me.

iDrive failed to completely backup some folders and files that I had selected, yet it did backup some folders and files that I had NOT selected.

In addition, it seemed to choke (by stalling completely) on some specific file types such that in eight hours overnight it made no progress at all beyond where it was when I went to bed (and no, I do not have my Energy Saver prefs set to put anything to sleep).

Note: The downloadable User Guide seems to be only for the Windows version.
