These are the final lines in my backup.log, I'm hoping this is from the 
last run on 3/31:

Previous backup seems to have failed, regressing destination now.
Regressing to Tue Mar 24 17:50:08 2009
Sending back exception CRC check failed of type exceptions.IOError:

I changed the script to write to a new repository last night - that 
process is still running. I forgot to delete the -v7 option so the new 
backup.log is full of info. However, grep did not find any CRC errors 
there yet.

Thanks,
