What data needs to be backed up?

[wmscottmc]

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) on an Android phone?

Thanks
