#Disaster Recovery

Disaster Recovery (spec.activeRedis.mode: peerof) is the hot-standby mode of Cross-Datacenter Replication: an upstream instance takes the application writes and fans directed replication links out to one or more downstream instances, each of which stands ready to be promoted if the upstream datacenter is lost. It is the default mode, and the only one available on Redis 6.0.

For how it compares with Active-Active, and for the mechanics both modes share, see Introduction.
