There's also synthetic full, where a full is followed by incrementals that are rolled into the full. So while the backup "across the wire" (so to speak) is an incremental, the backup software then plays that incremental against the previous full to create a new effective full and discards the incremental. I haven't seen much (if any) consumer-grade gear capable of synth fulls, though. You lose multiple point-in-time recovery capability, but it's space efficient and makes restores simple.
