You've restored from backups where files were locked during the backup?

I use "dbpause" all the time and run backups using Windows backup utilities. I don't think they have a problem backing up locked files because of the volume Shadow Copy functionality built into Windows (of course the service needs to be running). Our backups have been running on a number of machines over the last seven or eight years. Am I missing something?
