Time Machine stuck on "Finishing Backup"

[xAsteroidx]

I recently installed Windows 7 through Bootcamp. My hard drive was fragmented, so I restored my latest backup from Time Machine so that Bootcamp would have a clean partition. Everything went fine, and Windows 7 was able to load. Today I went to backup my computer before installing Mountain Lion, and TM keeps getting stuck at "Finishing Backup". I click the "X" to stop it, and it says that the backup had completed anyway. I tried using Disk Utility to repair and verify my TM volume like other threads suggested, but it keeps getting stuck. Does anyone have any suggestions? Thank you

Seems to be a bug with TM and ML. I am experiencing really slow backups. First back up took hours. Now it stays stuck on cleaning up.

Weird stuff. Hoping an update addresses this issue.

I haven't upgraded to Mountain Lion yet. I'm on Snow Leopard. I was trying to back up my computer on TM so that if a problem occurred upgrading to ML, I can just restore from the latest backup.
