[Camamber]

When i ignore some tables, it looks like okay. But then while, try restore-schema it still try to create them.

I found that you dont deal with skiping table during copying metadata. Why?

log.Println("Copy metadata")  
if err := copyPath(path.Join(dataPath, "metadata"), path.Join(backupPath, "metadata"), dryRun); err != nil {
    return fmt.Errorf("can't backup metadata with %v", err)
}
log.Println("  Done.")
