I subscribed for one year which ends in September. It worked fine until the last three months. Now it always says, "There is not enough space available for this backup." In the backup menu, I unchecked various files - same problem. I unchecked all files - same problem. Thinking it might help if I reinstalled the entire mac system for my 10.2.8, I reinstalled. (I first saved it to whatever the directions said to do, or so I thought). I lost everything - all documents, all iphotos, all hp photos, all movies, all addresses, all email accounts, all desktop, etc. My computer is a blank slate and still when I test idisk backup, it says, "There is not enough space available for this backup." How can that be? "Restore from idisk" or "Restore from drive" does nothing. I never saved anything to a cd or dvd because I couldn't get that to work when I tried to save a movie, so I gave up.
