I'm brand new to Palm. I have used backup assistant in the past and have used Android. I'm finding the easiest way to learn things is to read the website. Since I don't know what my Pixi is doing either and saw your question, I searched for "backup assistant" on the site and found:
Palm OS®: Not available on Palm OS devices.
Your phone is being backed up though as best I can tell by one or more ways. Your Palm profile backs it up and then if you sync with another account in addition (I use gmail), you have certain info (at least contacts, I'm not sure) backed up that way. I know it can get confusing. I still have many contacts backed up on Backlup Assistant which could serve as a secondary backup but can't currently be synced with the Palm, but if I got a different phone, they would be there.
What exactly do you want to do? It seems like there are several ways to back up. Please repost if you can.
So I read how to back up--step one export csv file in outlook. How/where is outlook on my phone??? I've had this phone a year and have never figured this out. Speak in plain English for those of us techno challenged.
