Step 4. Select Datastore

At the Datastore step of the wizard, select a datastore on which redo logs for verified VMs must be placed. Redo logs are auxiliary files used to keep changes that take place when VMs run in the virtual lab. As soon as a recovery verification job completes, redo logs are deleted.

To select a datastore for redo logs:

  1. Click Choose.
  2. Select a datastore from the list.

Step 4. Select Datastore Important!

If disks of verified VMs are located on VSAN and their size is greater than 2 TB, you must place redo logs on a VMFS datastore. For virtual disks greater than 2 TB, VMware vSphere creates snapshots in the SEsparse format. If you place redo logs on a VSAN datastore, Veeam Backup & Replication will fail to create snapshots for verified VMs since SEsparse snapshots are not supported on VSAN. For more information about snapshot formats, see
