第4步。选择Restore Mode（还原模式）
At the Restore Mode step of the wizard, choose the necessary restore mode and backup proxy for VM data transport:
- Choose a restore mode:
- Select Restore to original location if you want to restore the VMs with initial settings and to the original location. If this option is selected, you will immediately pass to the Summary step of the wizard.
- Select Restore to a new location, or with different settings if you want to restore the VMs to a different location and/or with different settings (such as VM location, network settings, fast provisioning settings and so on). If this option is selected, the vCloud Full VM Restore wizard will include additional steps for customizing VM settings.
- [For VM restore to the original location] Select the Quick rollback check box if you want to use incremental restore for the VMs. Veeam Backup & Replication will use CBT to get data blocks that are necessary to revert the VMs to an earlier point in time, and will restore only these data blocks from the backup. Quick rollback significantly reduces the restore time and has little impact on the production environment.
It is recommended that you enable this option if you restore the VMs after a problem that occurred at the level of the VM guest OS: for example, there has been an application error or a user has accidentally deleted a file on the VM guest OS. Do not enable this option if the problem has occurred at the VM hardware level, storage level or due to a power loss.
- Click the Pick proxy to use link to select backup proxies over which VM data must be transported to the source datastore. You can assign backup proxies explicitly or instruct Veeam Backup & Replication to automatically select backup proxies.
- 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 VM data.
During the restore process, VMs are processed simultaneously. 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 for writing data to target, current workload on these backup proxies, and selects the most appropriate resources for VMs processing.
- If you choose Use the selected backup proxy servers only, you can explicitly select backup proxies that will be used for restore. It is recommended that you select at least two proxies to ensure that VMs are recovered should one of backup proxies fail or lose its connectivity to the source datastore during restore.
