MongoDB Using Replica Sets as a Backup

MongoDB implements a form of replication they call replica sets. Referring to a repica set instead of just calling it replication is a helpful distinction that becomes more obviously useful when you are introduced to sharding in MongoDB since each shard should be comprised of a set of replicas unique to that shard, but we’ll get to that later.

For now, I want to show you how easy it is to setup and use replica sets. The setup and initial ‘recovery’ of data to all replicas in the set is quite simple. In this video I walk you through the entire process. The video is HD, so be sure to watch it full screen to get all the details.
