Q: Time Machine has not worked since upgrade to Lion
Hello,
I've noticed that my Mac Mini's Time Machine will no longer perform a backup - I keep receiving a "could not create the backup folder" error message. This problem only started after I upgraded my Mac Mini (2010 Model) to Lion, Time Machine had worked perfectly when I use to use Snow Leopard. I have both formatted and partitioned my Time Machine drives (the first drive was a Seagate Barracuda 7,200 RPM 1TB drive, the 2nd drive is a 2TB Porsche Drive I bought at my local Apple Store). Both drives, when I was partitioning them, were set to use the GUID Partition Scheme. The Seagate Drive is an Internal Hard Drive that is sitting in a ThermalTake 2-Bay Drive Dock which is connected by a USB Cord, the Porsche drive is an External Drive that is connected via a USB cord. I have also tried unmounting/remounting each drive, deleting the Time Machine "plist" file from my Library folder and restarting, and finally re-installing Lion from the recovery drive I made using the instructions on support.apple.com. Unfortunately, nothing I've done so far has solved the issue.
I checked my Console log for Time Machine and this is what I found:

It turns out that my Mac Mini needs to be physically repaired, Apple Support will be working on it for the next 3 days. I'm glad I have an AppleCare Protection Plan.
