is there any way to find out what time machine files are currently backing up?

Hi there...

on minute the time machine backed up everything, and the next minute is wants to backup another 16gb! Im not quite sure what happened to make it suddenly want to update another 16n as I hadn't added any new flies since the backup it had successfully completed.

Is there any way for me to see which files its currently backing up?

thanks for any help!

Nick
