During SureBackup, Instant Recovery, Instant Disk Recovery, or Other-OS FLR operation, the following error is seen in the VMware environment: Error during the configuration of the host: NFS Error: Unable to Mount filesystem: Unable to connect to NFS server. or An error occurred during host configuration. NFS mount <mount_server>:/VeeamBackup_<mount_server> failed: Unable to connect to NFS server. The NFS datastore cannot be mounted to the host, so vPower NFS-based restore fails.
To know which server to troubleshoot, you must first determine which server acts as the Mount Server for the Backup Repository where the backup files are stored. To find this, edit the repository where the backup files are located. There is a dropdown box on the Mount Server tab designating which server is being used as the Mount Server. *Note: As an isolation step, try changing which server is chosen as the Mount Server in the Repository settings and retry the restore.
