Data redundancy
Data redundancy is the practice of storing the same data in multiple locations to improve fault tolerance and availability. It helps protect against data loss due to hardware failure, corruption, or accidental deletion.
There are two main types of data redundancy:
- Hardware-based – Using systems like RAID or mirrored drives
- Software-based – Implemented through backups, replication, or cloud syncing
While redundancy enhances reliability, it should not be considered a substitute for proper backup solutions.
