Hard Disk Failure
Unfortunately, experience has shown that hard disk failure is not as infrequent as it should be, and that very little that can be done other than replacing the disk with a new one. You should therefore consider the following questions:
• What data will be lost if a disk fails? The FOXMAN‑UN Database? The operating system? User accounts? etc.
• How long does it take to get a replacement disk?
• Is the disk covered by warranty?
Preventive measures may include:
• Setting up a RAID1 or RAID5 to have disk redundancy,
• Performing a full RHEL disaster recovery backup on tape,
• Regularly saving / exporting the FOXMAN‑UN database backup on external server / disk,
• Implementing cold/warm standby.
