Hello,

I am seeing a similar error again on lucid 14.2-0ubuntu0.1 

The backup backup "Backing up...." dialog comes up and says "Preparing..." and then "Backup Failed".

I also had this issue with 14.0 and 14.1. fixed it but I am seening it again now. Does anyone else experience this or is it something on my end?

Here the output from the terminal:
