What is Self-Healing Archive Storage?

Archive Storage is defined as “Self-Healing” when it makes automatic additional copies of data. If the first copy of data is unreadable then a second or even third copy would be read automatically instead by the intelligent software that knows where all data is kept (online, offline, local or remote). The number of copies is kept constant. In addition, self-healing archive storage will often self-audit periodically by checking the validity of data through file hashing / digest or checksums.
