After I turn on my machine, the first couple of Time Machine backups seem to go OK, but after about an hour I get this error:
Unable to complete backup. An error occurred while creating the backup folder.
Latest successful backup: 7/31/11 at 12:32 PM
I'm running 10.7. Time Machine is backing up an internal HD to an external USB HD. I've already run Disk Utility to repair the Time Machine partition. It's a relatively new hard drive and didn't have any issues.
Here's what I've found in the Console's log filtered for backupd:
