Step 3. Select Failback Destination

In this article

    At the Destination step of the wizard, select the failback destination and backup proxies for vApp data transport during failback.

    1. Select a destination for failback. Veeam Backup & Replication supports the following options
    • Failback to the original vApp  — select this option if you want to fail back to the original vApp that resides on the source host. Veeam Backup & Replication will synchronize the state of the original vApp with the current state of its replica and will apply all changes occurred to the vApp replica while it was running in the disaster recovery (DR) site.

    If this option is selected, you will proceed to the Failback Mode step of the wizard.

    • Failback to the original vApp restored in a different location — select this option if you have recovered the original vApp from a backup in a new location, and you want to switch to it from the replica. Veeam Backup & Replication will synchronize the state of the recovered vApp with the current state of the vApp replica and will apply all changes occurred to the vApp replica while it was running in the disaster recovery (DR) site.

    If this option is selected, you will proceed to the Target vApp step of the wizard.

    Tip

    You can restore to another vCD.

    • Failback to the specified location — select this option if you want to restore the original vApp from a replica. In this case, Veeam Backup & Replication will recover a vApp to a new location with different settings (such as a vApp location, network settings, storage policy and so on). Select this option if there is no way to fail back to the original vApp or an already recovered vApp.

    If this option is selected, you will proceed to the Organization vDC step of the wizard.

    Note

    Mind the following:

    • If you fail back to the original vApp or the original vApp is restored in a new location, the difference between the virtual disks of the replicated vApp and their state is transferred to the original vApp. Veeam Backup & Replication does not transfer replica configuration changes such as a different IP address or network settings (if replica Re-IP and network mapping were applied), new hardware or virtual disks added while the replica was in the Failover state.
    • If you choose to fail back to the specified location, Veeam Backup & Replication will restore the entire vApp replica, including its configuration and virtual disks content.
    1. Click the Pick backup proxies for data transfer link to select backup proxies. Veeam Backup & Replication will use them to transfer data during failback. If vApps and their replica are located in different sites, select at least one backup proxy in the production site and one proxy in the disaster recovery site. If vApps and their replicas are locate in the same site, you can use the same backup proxy as the source and target one.
    2. In the Choose backup Proxy section, click Choose to assign a backup proxy. You can assign backup proxies explicitly or instruct Veeam Backup & Replication to select backup proxies automatically.
    • If you choose Automatic selection, Veeam Backup & Replication will detect backup proxies that are connected to the source datastore and will automatically assign optimal proxy resources for processing vApp data.

    vApps selected for failback are processed one by one. Before processing a new vApp in the vApp list, Veeam Backup & Replication checks available backup proxies. If more than one backup proxy is available, Veeam Backup & Replication analyzes transport modes that the backup proxies can use, the current workload on the backup proxies to select the most appropriate resource for vApp processing.

    • If you choose Use the selected backup proxy servers only, you can explicitly define backup proxies that must be used for data transfer. It is recommended that you select at least two backup proxies to ensure that failover is performed should one of backup proxies fail or lose its connectivity to the source or target datastore.
    1. If you want to perform failback with the quick rollback option, select the Quick rollback (restore changed blocks only) check box.

    Important

    It is recommended to use the quick rollback option if you fail back to the original vApp after a problem occurred at the guest OS level of a VM added to a vApp. Do not use quick rollback if the problem has occurred at the VM hardware level, storage level or due to a power loss.

    Step 3. Select Failback Destination 

    Restoring Storage Policies

    If the replicated vApp was associated with the storage policy, in the failback to original location scenario, Veeam Backup & Replication will associate the restored vApp with this storage policy.

    When you click Next, Veeam Backup & Replication will check storage policies in the virtual environment and compare this information with the information about the replica storage policy. If the original storage policy has been changed or deleted, Veeam Backup & Replication will display a warning. You can select one of the following options:

    • Current — the restored VM will be associated with the profile with which the original VM in the production environment is currently associated.
    • Default — the restored VM will be associated with the profile that is set as default for the target datastore.
    • Stored — the restored VM will be associated with the profile that was assigned to the original VM at the moment of replication.

    I want to report a typo

    There is a misspelling right here:

     

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