OCI Full Stack Disaster Recovery (Full Stack DR) is a fully automated service that orchestrates end-to-end disaster recovery for complete cloud applications, enabling recovery across OCI regions or availability domains, covering infrastructure, databases, and application middle tiers.
Overview
This blog explains how to setup and orchestrate the Active/Passive DR on the OCI Compute VMs.
For active-passive DR topology, VMs should be up and running on the DR side and referred as non-moving instances in Full Stack DR, add all the block volumes attached to compute instances in the primary region to the replicated volume group.
Boot volumes do not need to be replicated. However, if you store application data on the boot volume (root partition), you may require other mechanisms, such as rsync or robocopy , to keep the primary and standby compute instance boot volume file systems in sync.
