Release Notes

This is the first release of Trilio Site Recovery for OpenStack, delivering self-service disaster recovery for Nova VMs. The API enables tenants to replicate Cinder volumes to a secondary OpenStack site via Pure Storage FlashArray and automate failover, failback, and non-disruptive DR testing workflows.

New features

Volume Replication to Secondary Site
Replicate Cinder volumes attached to Nova VMs to a second OpenStack site using Pure Storage FlashArray as the underlying replication engine. Replication is managed per-VM and tracks all attached volumes automatically.
Automated Failover
Trigger a failover of protected Nova VMs to the secondary OpenStack site. The API orchestrates volume promotion on the FlashArray, re-attachment to new VM instances, and network reconfiguration at the recovery site.
Automated Failback
After a failover event, restore workloads to the original primary site with a single API call. The failback workflow re-synchronizes volume data and cleans up resources at the secondary site.
Non-Disruptive DR Testing
Validate your disaster recovery plan without impacting production workloads. The test failover API creates temporary clones of replicated volumes at the secondary site, boots test VMs, and tears down the test environment on completion — leaving replication uninterrupted.
Self-Service Tenant API
OpenStack tenants can manage their own DR protection groups, replication schedules, and recovery operations directly through the Trilio Site Recovery REST API without requiring administrator intervention.
Protection Group Management
Organize one or more Nova VMs into a named protection group with a shared replication policy. The API supports create, read, update, and delete operations on protection groups, as well as adding and removing member VMs.
Replication Schedule Configuration
Define RPO-aligned replication schedules for protection groups. Supported intervals allow tenants to balance recovery point objectives against storage and network overhead.
Recovery Job Status and History
Query the status of in-progress and completed failover, failback, and test failover jobs. Each job record includes start time, end time, status, and per-VM operation details to assist with auditing and troubleshooting.
