Functions of the database copy utility

Executor: HiRDB administrator: The HiRDB administrator must periodically back up databases to protect against possible database errors. To back up a database, use the database copy utility (the obtained backup can be used only to restore the same HiRDB's database). To restore the database due to a disk error, etc., use the created backup copy as an input to the database recovery utility (pdrstr command) to restore the database.
