quotarestore —
restore dumped quota information to a file system volume
  
    | quotarestore | [ -d] file-system
      [dump-file] | 
The quotarestore program restores dumped quota
  information to a file system. The file dump-file should
  be in the format produced with
  quotadump(8). The quotas,
  expiration times, and configured grace times listed in the dump file are
  loaded into the named file system. The file-system
  argument should be a file or directory on the (mounted) file system, not a
  device special file.
If the -d option is given, quota entries
    on the file system that are not mentioned in the dump file will be deleted.
    Otherwise, they are left alone.
If the dump-file is not specified, standard
    input is used.
The quotarestore command appeared in
  NetBSD 6.0.
