Step 6. Select Destination for Virtual Disk Updates
This step is available if you recover workloads to a new location or with different settings.
At the Datastore step of the wizard, you can select where to store redo logs when a VM is running from a backup. Redo logs are auxiliary files used to keep changes that take place while the recovered VM runs.
By default, redo logs are stored on the vPower NFS server. For more information, see the Veeam vPower NFS Service section in the User Guide for VMware vSphere.. You can store redo logs on any datastore in the virtual environment, if necessary. Redirecting redo logs improves recovery performance but makes Storage vMotion not possible for ESXi 5.5. As soon as a recovery verification job completes, Veeam Backup & Replication deletes redo logs.
To redirect redo logs:
- Select the Redirect write cache check box.
- Click Choose and select a datastore from the list.
If the size of recovered VM disks is greater than 2 TB, you must not place redo logs on a VSAN datastore. Otherwise, Veeam Backup & Replication will fail to create a snapshot for the recovered VMs. For more information, see VMware Docs.
