Disaster recovery of volumes and file systems in Docker environments
InfoScale Enterprise helps you replicate both Docker infrastructure managed by Docker Daemon and data volumes of Docker Containers or choose to replicate only the Docker infrastructure or the data volumes. After replicating the data, metadata associated to containers, InfoScale Enterprise migrates the data volumes and infrastructure to the disaster recovery site.
VVR and VFR replication technologies replicate volume block devices and file system respectively on the DR site with applications in active state. When the primary site goes down or a network disruption occurs, the VCS Global Cluster Option (GCO) configured for the primary and DR site provides coordinated failover of applications. The DR site takes over the VVR and VFR primary role.
In case you want to move back to the original primary for VVR replication, perform a role transfer. VCS GCO provides the option to select the primary VVR site after a network partition while the applications remain active.
For more information on setting up VVR and VFR, refer to the Storage Foundation and High Availability Solutions Replication Administrator's Guide.
