Data replication strategies for availability include synchronous replication (real-time copying to secondary nodes for zero data loss), asynchronous replication (delayed copying for performance), and multi-region replication (storing copies across global data centers). Database clustering (e.g., MySQL Group Replication) ensures high availability, while distributed file systems (Ceph, HDFS) replicate data across nodes. Quorum-based writes require majority confirmations to prevent splits, and erasure coding splits data into fragments with parity for space-efficient redundancy.
