I thought similar to Kjell, yet opposite: If the size is over the threshold, just do an extra backup at a lower level, e.g. make a level 2 backup if the level 5 backup is above 1 Gb and a level 3 backup if the level 5 backup is above 100Mb or similar. I would expect it to be possible to mix this with the backup scheme that you've already described, but I've absolutely no knowledge of NBackup and may be completely wrong.
