Time Machine Problem

[Vapor]

I have done a clean install of Snow Leopard and used migration assistant with time machine to bring system back to original state. My problem is time machine now says I don't have enough space for a backup. The iMac has a new hard drive so I am not sure what is going on. I could always Format and restart TM but I am not real happy about trying that. It will be may last resort. Any Ideas?

Did you already Restored the freshly installed SL from your time machine back up? If so, the computer is as you left it. You could erase the back up drive and start the progress of back up-ing. No harm done, then. Because the Mac has properly been transformed to the last known situation you're old hard drive was at

OR

Did the error occured while peforming the migration from the back up?
Then this could be because the new harddrive is smaller or anything.

Specify your exact problem, please.

It is fresh and all good. I guess I will format time machine in the morning and let it run all day.
