🔄 What is VM Replication?

VM Replication is a feature that continuously or periodically copies a virtual machine’s disk and configuration from a primary host to a secondary one. In case of failure, the replica can quickly be booted to restore service availability.

✅ Replication is ideal for mission-critical systems where RTO (Recovery Time Objective) needs to be minimized.

⚙️ Setting Up VM Replication in Arcfra

🔹 Steps:

1. Go to Backup & DR → Replication tab.
2. Click Replication plan → Createa Replication Plan.
3. On Pop Up window, fill out the information needed:
   • Basic Information and VM that will be replicated
   • Replication schedule
   • Retention policy
   • Replication VM Options
   • Test replication configuration
4. New Replication plan created.
5. Click the plan and Perform Manually.
6. Wait until the Replication process success
   

🔁 Arcfra uses block-level incremental sync for efficiency.

🚨 Failover and Failback Process

If the primary VM or host becomes unavailable, you can initiate failover from the web interface.

🔹 Manual Failover

1. Go to Replication → Replication Plan.
2. Scroll down to Replication Object Menu
3. Click Failover.
4. Wait until New VM Created on target Cluster
5. Check data on New VM

This boots the replicated VM as the active production instance.

🔹 Failback (Return to Primary Site)

Once the original VM or site is restored:

1. On Replication plan → Replication Object → Recovery → Failback.
2. Create Failback Job
3. Source VM will be UP and data already synchronized

⚠️ During failback, verify data consistency before resuming production use.

💡 Best Practices for Replication

• Use dedicated storage or bandwidth for replication traffic.
• Avoid overlapping IP addresses between sites.
• Combine replication with snapshot or backup for layered protection.
• Test failover regularly to ensure your DR plan works.

✅ Final Thoughts

VM replication in Arcfra is a powerful feature that ensures availability and minimizes downtime. Whether you’re protecting a database, web server, or business application, replication lets you build a resilient cloud infrastructure without needing external tools.
