I'm no longer an Outlook sufferer myself, using KDE-PIM. I have a calendar going back to the 80's in icalendar format and all my contacts in vcal format under Kaddressbook. I back them up to a 128M USB flash drive that I carry in my pocket with my. The advantage of the Linux programs like mine is the ical and vcal are standardized and in plain text format so it worst case I can view the contents in dos edit on a dos machine if I had to. Everything else, receipts, pictures and such get scanned and burned to cd.
