Replication & DR

Replication & Disaster Recovery

You have root-level control of the cluster, so you replicate data for disaster recovery between ZCS clusters and any other Ceph cluster you administer.

Replication options

Object (RGW multisite). Replicate buckets and objects between zones or clusters for an active-active or active-passive object store.
Block (RBD mirroring). Asynchronously mirror RBD images to a second cluster for block-level DR.

Common topologies

Replicate in to ZCS. Point an existing on-prem or third-party Ceph cluster at your ZCS cluster to use it as a recovery target.
Replicate out from ZCS. Replicate your ZCS cluster to another ZSoftly region, to an on-prem cluster, or to any Ceph cluster you operate.

Both endpoints are standard Ceph, so replication is not tied to ZSoftly. You pair a ZCS cluster with clusters you run anywhere.
