Time machine is not working

Question

I just got a new imac intel core i7 which is an upgrade from my power mac G4 MDD which I got in 2003. I transferred all the information from the power G4 using time machine and it worked fine. I then upgraded the OS to 10.6.4 given imac is intel core. All programs are working fine except I am unable to use time machine. It runs for a few gb and then the following error come on time machine buddy:
Starting standard backup
Backing up to: /Volumes/Backups/Backups.backupdb
Ownership is disabled on the backup destination volume. Enabling.
Backup content size: 237.9 GB excluded items size: 818.0 MB for volume Macintosh HD
No pre-backup thinning needed: 284.58 GB requested (including padding), 930.57 GB available
Waiting for index to be ready (101)
Indexing a file failed. Returned 1 for: /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/wx-2 .8-mac-unicode/wx/lib/floatcanvas/Utilities/_init_.py, /Volumes/Backups/Backups.backupdb/van (5)/2010-08-17-184416.inProgress/75B311E0-7C50-4BD3-B7AD-03E3A1B883B2/Macintosh HD/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/wx -2.8-mac-unicode/wx/lib/floatcanvas/Utilities/_init_.py
Aborting backup because indexing of file failed.
Stopping backup.
Copied 70375 files (17.4 GB) from volume Macintosh HD.
Copy stage failed with error:11
Backup failed with error: 11
Then when I try to verify and repair the disk, it does do it and keep on showing: " invalid node structure, invalid key length and invalid record count"
I have changed the external hard drive twice so I doubt that is the problem. Please help

I excluded both files and it just worked. It seems to have backed up all the files.
That's a bit surprising (but good).
Is there a way to check?
If the backup completed normally, everything should be fine. If you want, you can browse your backups, and perhaps restore a few selected things to alternate locations (such as your desktop), and compare them, just to be sure. (If you're not sure how to do that, see #16 in the FAQ.)
Also are the files that I excluded important?
They're not critical, and reinstalling OSX would get fresh copies.
I did talk to AppleCare 4 days ago. The gentleman was very nice and helpful. He did not understand how to fix the problem so he was going to push it up to the next level but they have not responded. I must say that I am very disappointed. I have 3 IMAC computers, 1 power mac G4, a macbook pro laptop, an ipad, 2 iphones and several itouches and ipods. I love Apple but I am very disappointed with the service. I always get apple care when available and, fortunately, have never had to use it. Now I did and I really have not gotten the help that I wanted. Just my ranting. No matter, I am still going to stay with apple.
They will get back to you, sooner or later. Some of them don't seem to know a great deal about Time Machine, unfortunately, and this is not a common situation.
As long as you do have completed backups, you're probably ok. I'd suggest just keeping an eye on it for a while; if nothing else goes wrong, and you haven't heard from AppleCare, then decide if you want to go farther.
If you do, I'd suggest reinstalling OSX from your Install disc (that won't touch anything else). Then
download and install the 10.6.4 "combo" update. Info and download available at: http://support.apple.com/kb/DL1048 Be sure to do a +Repair Permissions+ via Disk Utility (in your Applications/Utilities folder) afterwards.
That will get you a new, fresh copy of OSX. Try a backup to make sure everything's still ok, then remove the exclusions and see what happens. If it runs ok, then something in those two files was corrupted -- unusual, but as they say, "stuff happens."
Keep us posted.
