By default (you can change it), it saves in your Home folder: Users/user/movies/final cut pro backups. They should be there.
Having said that, I've found that the backup feature does not always work. I've found backup libraries in very unexpected places. And I have also experienced the failure to make any backup files whatsoever. So I find myself checking in the Finder regularly.
Thank you Russ, you answered my question as well. As long as I leave it at the default setting it backups regularly at the moment. However, I wanted to save space on main HD and elected to go external. No good. Is this a problem with FXP X and do you know whether Apple is considering solving the problem in the future? Sure would help.

No inside info about any Apple plans.
I do think it's worthwhile to report it on the Feedback link (from the FCP X men).
PS: Meant to comment that these BU libraries generally don't take up a lot of space.
The project was found in backup -- but a different version of it, but at least it was there. I guess this random issue exists with FXP X. I saved my project now in three different places, included external drive and I forced a backup. It's too bad this problem popped up when I had a deadline, but isn't that the way it goes?
Thank you all for your replies.
I found my project and backed it up while talking to a support rep on the phone. She sent me this link for back-up information:
