Thanks for all the helpful replies. My problem was that I was forgetting to plug the phone into the charger overnight resulting in a drained battery. I would lose all data when I would plug the phone back in.

Looking at the replies it seems that this is normal for the phone. Although this never happened to me in my Plam V. It would store data internally for about 15 days on a drained battery.

I will look into bachupbuddy. Where can I find it???
