I am proposing three: - NEVER: The bitmap is never synchronized against what was copied. - ALWAYS: The bitmap is always synchronized, even on failures. - ON-SUCCESS: The bitmap is synchronized only on success. The existing incremental backup modes use 'on-success' semantics, so add just that one for right now.
