Interestingly I get the exact same issue if i restore to my local graph and try and run a backup.
Your corrupt index thing got me thinking, so i removed all the indexes on the database and tried to run the backup again.
This time it gets further, but then seems to run out of memory, not sure what i need to change to see if it completes.
