Replica Failover and Failback

In this article

    In case of software or hardware malfunction, you can quickly recover a corrupted VM by failing over to its replica. When you perform failover, a replicated VM takes over the role of the original VM. You can fail over to the latest state of a replica or to any of its good known restore points.

    In Veeam Backup & Replication, failover is a temporary intermediate step that should be further finalized. Veeam Backup & Replication offers the following options for different disaster recovery scenarios:

    • You can perform permanent failover to leave the workload on the target host and let the replica VM act as the original VM. Permanent failover is suitable if the source and target hosts are nearly equal in terms of resources and are located on the same HA site.
    • You can perform failback to recover the original VM on the source host or in a new location. Failback is used in case you failed over to a disaster recovery (DR) site that is not intended for continuous operations and would like to move the operations back to the production site when the consequences of a disaster are eliminated.

    Veeam Backup & Replication supports failover and failback operations for one VM and for several VMs. In case one or several hosts fail, you can use batch processing to restore operations with minimum downtime.

    I want to report a typo

    There is a misspelling right here:


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