Yes, that's exactly what I mean.

I'm unaware of any situation or case where a single folder or directory would be mysteriously missing during a backup. So, when you look in the /Users folder on the backup drive, it literally has a different number of files than it does on the source? Or, are you determining the status of the accounts by what's visible in the login screen when you boot from the backup?

If the latter, it's possible that your NetInfo database is damaged, and doesn't copy properly. If so, we can step you through reconstructing it, but it'd probably be better to do it through email...
