How to recover my Time Machine backups from iCloud

Hi,

I am trying to run my TimeMachine backup and I think I made a mistake when I linked the same disk at the time I created iCloud account. Now, the disk is called iDisk and would only let me see the contents if I am logged in with MobileMe, which I have not really used after I created it. Will I able to see my TimeMachine backups again or did I manage to delete it I set up iCloud? Help as if I could not see the disk (or iDisk) contents then I lost my 2011-2012 TimeMachine backups.

Regards,

Evangeline
