It may be possible that the old savepoints have been corrupted and deleting them thorugh "My Repositories" might fix this issue.
***NOTE If you wish to keep the Savepoints that will be deleted, you can navigate to the Repository with Windows Explorer and copy the savepoints off to another location.
Once the Delete is complete try running the failing backup again.
