- Recovery
- Redundancy
- Replication

Hadoop's Replication mechanism allows for automated recovery of data in case of a DataNode failure. It ensures that multiple copies of data blocks are maintained across the cluster, providing fault tolerance and reliability. If a DataNode becomes unavailable, Hadoop can retrieve the data from other replicated copies.
