vSphere VM Configuration Assessment Report

Previous page Print this Topic

Table of contents

This report analyzes configuration of VMs in your virtual environment, and shows potential issues and possible limitations that could cause backup process to fail or prevent VMs from being properly backed up.

noteNote

This report applies to VMware infrastructure only.

Description

The vSphere VM Configuration Assessment Report helps you to assess VMs readiness for performing backup with Veeam Backup & Replication. It analyzes configuration of VMs in your virtual environment and identifies VMs that cannot be properly backed up due to configuration limitations.

The report takes into account the following criteria when analyzing VM configuration:

Criterion

Description

Application-Aware Image Processing

VM Guest OS

The report checks guest OS to detect VMs with Windows Server 2000 guest OS.

To create a transactionally consistent backup of VMs running VSS-aware applications, Veeam Backup & Replication uses application-aware image processing. To enable application-aware image processing, it is required that Windows Server 2003 or later OS version is installed inside VMs.

VMware Tools

The report analyzes your virtual infrastructure to find VMs that do not have with VMware Tools installed or running.

To enable backup with application-aware image processing, it is required that guest OS running inside your VMs have VMware Tools installed and running.

Configuration Issues

VM Names

The report analyzes your virtual infrastructure to find VMs with @ \ / < > symbols in display names.

Processing of VMs with @ \ / < > symbols in VM name is not supported for vCenter 5.1 and earlier. For more information on special characters used in display names, see this VMware KB article.

Datastore Names

The report analyzes your virtual infrastructure to find VMs on datastores with @ symbols in display names.

Processing of VMs on datastores with @ symbols in datastore name is not supported. For more information on special characters used in display names, see this VMware KB article.

Fault-Tolerant VMs

The report analyzes your virtual infrastructure to find fault-tolerant VMs.

Veeam Backup & Replication cannot create snapshots for fault-tolerant VMs for vSphere 5.x or earlier. If you want to back up fault-tolerant VMs, you must upgrade them to the new vSphere 6.0 format.

Datastore Free Space

Datastore Free Space

The report analyzes your virtual infrastructure to find datastores that have less than 10% of free space.

When Veeam Backup & Replication backs up a VM, it triggers a VMware snapshot that is normally stored next to VM files on the source datastore. To eliminate the problem of datastores running low on free space during backup, it is required that the free space is more than 10%.

Virtual Disks

Disks Engaged in SCSI Bus Sharing

The report analyzes your virtual infrastructure to find VMs with disks engaged in SCSI bus-sharing.

Snapshots are not supported on disks connected to controllers configured for bus-sharing configuration. For more information, see this VMware KB article.

Independent Disks

The report analyzes your virtual infrastructure to find VMs with Independent disks.

Smapshots are not supported on virtual machines with Independent disks. For more information, see this VMware KB article.

RDM Virtual Disks

The report analyzes your virtual infrastructure to find VMs with RDM virtual disks in the physical mode.

Veeam Backup & Replication does not support RDM virtual disks in the physical mode and independent disks (these disks are skipped from processing automatically). To backup VMs with pRDM disks, you should convert these disks to vRDMs. For more information on how to switch a raw data mapping between physical and virtual compatibility modes, see VMware KB article.

VMware CBT

Existing Snapshots

The report analyzes your virtual infrastructure to find VMs with existing snapshots.

To use VMware Changed Block Tracking for incremental backup, it is recommended that all existing snapshots are removed.

Hardware Version

The report analyzes your virtual infrastructure to find VMs with hardware version 4 or earlier.

To use VMware Changed Block Tracking for incremental backup, hardware version of VMs should be 7 or later.

Parameters

Scope: defines a list of Groups or Objects that will be analyzed in the report. By default, the VMware Virtual Machine Group is selected.

Sample Usage

Obtain a list of VMs in your virtual environment that could experience potential issues with backups and get guidance on how to resolve these issues.

Instructions

1.Open the vSphere VM Configuration Assessment Report.
2.Leave the Scope section without changes.
3.Click Run to view the report.

Report Output

The Summary pie charts will show the following information:

The Virtual Machines Overview chart will display total number of VMs with potential issues and total number of VMs ready for backup.
The Potential Issues chart will display the number of VMs with Application-Aware Image Processing, Datastore Free Space, Virtual Disks, VMware CBT and Configuration issues described in the Summary section.

The details table will provide details and recommendations for each VM issue.
