About Replica Sets A replica set is a process that synchronizes data across multiple machines.Replica collectives provide data redundancy and extend data availability. Saving data on multiple servers avoids data loss due to a single server.It can also be freed from hardware failures or service outages, with additional copies of data that can be dedicated to disaster recovery or backup from a single machine

A replica set (Replica set) is a cluster of MongoDB instances consisting of a primary (Primary) server and multiple backup (secondary) servers. With replication, updates to the data are pushed from primary to other instances, and after a certain delay, each MongoDB instance maintains the same copy of the DataSet. By maintaining redundant database replicas, you can achieve offsite backup of data, read-write
