Before you perform Instant VM Recovery, check the following prerequisites:

You can restore a VM from a backup that has at least one successfully created restore point.
You must have at least 10 GB of free disk space on the vPower NFS datastore to store redo logs for the restored VM. By default, the redo logs are written to the C:\ProgramData\Veeam\Backup\NfsDatastore folder on the vPower NFS server.

If you do not plan to redirect virtual disk updates to a VMware vSphere datastore, make sure that you have enough free space on the Veeam vPower NFS datastore. Approximate amount of free space required is the amount of RAM for the restored VM + 200 MB. For example, if the restored VM has 32 GB RAM, you must make sure that you have at least 32.2 GB of free space on the Veeam vPower NFS datastore.

If you are recovering a VM to the production network, make sure that the original VM is powered off to avoid conflicts.

On non-Microsoft Windows SMB3 storages, for example, Tintri, Veeam Backup & Replication may display the "Failed to disable integrity bit on disk N" warning during VM restore. You can ignore this warning for non-Microsoft Windows SMB3 storages.
