These registry keys are great for daily work because they automate and control cleanup of vPower NFS datastores eg. after Instant Recovery operations.

Without these keys, you have to manually unmount the datastore in vSphere or keep them in the configuration:

VPowerNFSUnmountDatastore (DWORD, 1)

VPowerNFSUnmountDatastore (DWORD, 1)

Purpose: This key controls whether Veeam Backup & Replication automatically unmounts the vPower NFS datastore after completing a restore operation (such as Instant VM Recovery).

Usage:

Value 1: Enable automatic unmounting. Value 0 (or missing): Keep the datastore mounted after the job finishes.

How to Set:

Create a DWORD value named VPowerNFSUnmountDatastore under the Veeam registry path (usually HKLM\SOFTWARE\Veeam\Veeam Backup and Replication) and set it to 1.

vPowerNFSUnmountDatastoreRetryTimeoutMinutes (DWORD, 1)

Purpose: Defines the timeout (in minutes) to keep retrying unmounting the vPower NFS datastore if the first attempt fails.

Usage:

The value specifies how long Veeam will keep retrying before giving up.

For example, 1 means retry unmounting for up to 1 minute.

How to Set:

Create a DWORD value named vPowerNFSUnmountDatastoreRetryTimeoutMinutes in the same registry location and set the desired number of minutes.

How to Use:

These keys are typically used to control cleanup behavior of vPower NFS datastores after restores.

After adding or modifying the keys, you may need to restart the Veeam services for the changes to take effect.
