Permanent Failover

In this article

    Permanent failover is one of the ways to finalize failover. When you perform permanent failover, you permanently switch from the original VM to it replica. As a result of permanent failover, the VM replica stops acting as a replica and starts acting as the production VM.

    Note

    We recommend you to perform permanent failover only if the original VM and its replica are located in the same site and are nearly equal in terms of resources. In this case, users will not experience any latency in ongoing operations. Otherwise, perform failback.

    The permanent failover operation is performed in the following way:

    1. Veeam Backup & Replication powers off the VM replica.
    2. Veeam Backup & Replication removes short-term and long-term restore points of the VM replica from the replication chain and deletes associated files from the datastore. Changes that were written to the protective virtual disks (<disk_name>-interim.vmdk) are committed to the VM replica to bring the VM replica to the most recent state.
    3. Veeam Backup & Replication removes the VM replica from the list of replicas in the Veeam Backup & Replication console.
    4. To protect the VM replica from corruption after permanent failover is complete, Veeam Backup & Replication reconfigures the CDP policy: adds the VM replica in the list of processed VMs and add the original VM to the list of exclusions. When the CDP policy starts, the original VM is skipped from processing. As a result, no data is written to the working VM replica.

    I want to report a typo

    There is a misspelling right here:

     

    I want to let the Veeam Documentation Team know about that.
