Losing our cloud saved data is not something that happen frequently. However, I think that a good way to prevent this is by not shutting down your console unexpectedly, another way is by not interrupting the “syncing your progress” window when it appears.

The last one is that if you switch between consoles and one is offline with the current progress, connect it to the internet in order to upload this information before using the other console.

corrupted saves which you could remedy on the 360 with a backup. I'm just confused about the decision.

Kinda weird. I’ve never heard of a profile getting corrupt before....

Any options that don't involve phone support? I've heard horror stories about them.
