ufsdump is the problem, not ufsrestore. If you ufsdump an active

ufsdump. Needless to say, this renders ufsdump useless for backup
when the file system also needs to accommodate writes.
This is why there is a ufs snapshot utility.
You'll have the same problem. fssnap_ufs(1M) write locks the file system
when you run the lock command. See the notes section of the man page.
