RFC (Replication Factor C)

Replication Factor C (RFC) is a data security concept where multiple copies of data are stored across different servers or locations. If some copies are lost or corrupted, the remaining copies ensure the data remains available and intact. Think of it like having several backup copies of important documents; even if one copy is damaged or missing, others still keep the information safe and accessible. This approach enhances reliability, fault tolerance, and disaster recovery in distributed data storage systems.
