    Backup: Fix formatting errors
    
    There are a couple of places in the Backup manager where we are passing
    a set instead of a dictionary to LOG.warning, which leads to an error:
    
      TypeError: not all arguments converted during string formatting
    
    This patch converts those sets into dicts, as they were intended.
    
    Closes-Bug: #1898621
