I regret that I had not read other's reviews before purchasing this software. I have spent more than a week trying to back up to multiple disks (as described on p 37 of the pdf manual which came on my installation disk. I now gather that others have had the same problem. Elswhere manual appears to contradict itself: on p. 47 it says that "you cannot clone a volume over a network, but on the following page it appears to tell you how to do so.But my main concern what appears to be non-existent support. There is evidently no telephone support. The Intego web site has provision for requesting on-line support. Problems written in the space provided receive acknowlegement by return, with a ticket reference number, but my 3 requests so far - the earliest 7 days ago - have not yet resulted in any help.
