Thanks for comments. I use mainly MS Office for busienss so no long video or
so. But I do from time to time a copy on DVD, additionally to daily back-ups
on extrenal HD, for double security.
Yet you comments do not answer exectly my questions, on using Vista back-up
utility. Especially the question - do opened but not modified files, between
two backups are backed-up, as I think to read in one of the posts?
