288 views

RAID (Redundant Array of Independent Disks) enhances performance or provides fault tolerance by combining multiple disks into a single unit. However, it is not a substitute for backup because it doesn't protect against data corruption, accidental deletion, or catastrophic events like fire or theft. Backup involves copying data to a separate location to ensure recovery in case of data loss. Using both RAID and backup together offers robust data protection.

FAQs & Answers

  1. What is RAID used for? RAID is used to enhance performance and provide fault tolerance by combining multiple disks into a single system.
  2. Why isn't RAID a backup solution? RAID does not protect against data corruption, accidental deletion, or disasters, which is why a proper backup is essential.
  3. How does a backup differ from RAID? A backup involves copying data to a separate location for recovery, while RAID focuses on performance and fault tolerance.
  4. Can I use RAID and backup together? Yes, using both RAID and backup together provides a comprehensive data protection strategy.
