what data needs to be backed up?

If an Android app is purchased, does the data for that app need to be backed up or is it all auto synced with google?

For example, on my blackberry I have a memo app that I purchased, and I back up the data to my pc. What data, if any, needs to be backed up (to a pc) from a Droid X?

Thanks

 

ok thanks. Just to make sure I am clear on this, 3rd party apps, like colornote, or a memo app, dont sync the data to google automatically, but the droid backup program does allow you to backup the app, and/or the data to a pc.

correct?

 

So from what I am reading, most Android users dont backup their phones the way that palm, blackberry, or windows mobile users do.

I understand that basic PIM data such as contacts and calendar is auto synced with google. But what about purchased apps, like a memo/todo app that lets you enter text on the phone? How are these apps (and the data) backed up on the Droid X, or do most users just not bother backing up?

From what I understand, Android does not even include a backup to pc application, but correct me if Im wrong.

Thanks.
