Final answer:
RAID 1 offers redundancy by mirroring data across multiple disks, which protects against data loss in case one of the drives fails.
Step-by-step explanation:
RAID 1 provides redundancy through a process called disk mirroring. Disk mirroring, also known as RAID 1, involves the replication of data to two or more hard drives simultaneously. This redundancy ensures that if one disk fails, another copy of the data is immediately available, thereby protecting against data loss. The concept of disk mirroring is an essential part of RAID (Redundant Array of Independent Disks) technology, which is widely used in enterprise storage systems to enhance data integrity and availability.
