Most of us these days tend to backup most of our data regularly (well you should!), but how often do you bother backing up your emails and contacts?
I am guilty of never backing mine up until it is too late. When my last system died I was lucky that the hdd was ok so I could retrieve the emails and contacts files from the hdd to import back into the fresh copy of Outlook, but even after this I've just realised I've never backed up my emails on this system since I built it. Mad considering my emails contain all of my registration details for many sites, plus all of the confirmation, serial numbers and confirmation details for all of the server based software I use. So after realising this I think it's time I actually do a backup!
