Hi Gavin,
Can I see the new log file please?
The previous backup attempt halted while trying to archive an unreadable, odd named file in your site's root. If it gets stuck at the exact same point you will either have to remove that file completely, or use the Files and Directories Exclusion feature to manually exclude such file from the backup. Since this is pure speculation at the moment, I would love to see the log file and figure out if my hunch holds any truth.
