世論 What Japan Thinks

japan.internet.com published the results of a survey carried out in the middle of September by JR Tokai Express Research into how people back up data at home. They interviewed 330 people employed in private or public enterprises; 82.4% were male, 13.0% in their twenties, 43.0% in their thirties, 27.0% in their forties, 14.5% in their fifties, and 2.4% in their sixties.

I, like almost half in this survey, back up my important stuff (mostly photos) to CD-R on a semi-regular basis. Actually, last month I almost had a back up muck-up when wifey’s install of Outlook Express suddenly lost all its address book after she tried to add a new address and I had been rather remiss about backing it up recently. It turned out, however, to be a bug in a recent Microsoft security update, which fortunately is easily resolved by following the procedure described in the linked Knowledge Base article.
