Although the storage system with a configuration of RAID 1, RAID 5, or RAID 6 provides data
reliability enhanced by redundancy, there is a chance that user data could be lost due to an
unexpected host, storage system hardware, or software failure. Therefore, users are
requested to back up all data.
