FONTANITUM  As most of Yellow Mug Software apps, FileChute is effective, simple and elegant.

FONTANITUM  Plenty of flashy, useless graphics, poor UI .... basic work done

Make sure you have plenty of room on your HD, Personal Backup X5 is VERY hungry. If you have changes in (say) 30% of your disk, you need al least 40% to 50% extra space available on the HD where the backup copy is. Apparently this "software" copies the WHOLE batch, then notices there are duplicates and deletes them, instead of doing this task, if not necessarily file-by-file, but at least (say) Gb by Gb. I shared this suggestion with the developer (he was staffing the Intego "castle" in a Mac show). His Highness thought it wasn't a bad idea and he would "think" about it for "one of" the upcoming releases.
