Restoring a SQL Geodatabase Feature Class with Attribute Rules

[JoeBorgione]

I clobbered a feature class in our live Egdb that has attribute rules.  When restoring feature class from the incremental backup from last night, our DBA is getting this error:

Not sure what it means, but we have experienced other 'gotchas' with our feature classes that have attribute rules associated with them.  What we just did was restore the entire live egdb from last night to our test egdb, so I just need to truncate the live feature class and then append the test features back in, and I'm good to go.

Can anyone explain?
