arcserve-KB : How to backup a VMware virtual Machine using arcserve backup?

Last Update: 2016-11-23 15:48:06 UTC

This document provides a step wise approach for configuring backup for VMware based Virtual Machines using ARCserve Backup.


Please refer to the below video Link which is an overview of arcserve Agent For Virtual Machine for Vmware.



Step 1:
 Plan and configure the data store / transport mode for your backup environment.

Data Store:

The CA ARCserve Backup Agent for Virtual Machines lets you protect VMware-based data that resides on local storage and on a storage area network (SAN). For all data store types, the VMs must be accessible from the backup proxy system.


The list that follows describes the environment configuration requirements for each of the data store types:


■ SAN, iSCSI Data Stores:The backup proxy system must be attached to the same disk where the VM resides and must be attached using the same SAN, iSCSI infrastructure.


■ Local Storage Data Stores: The VMs must reside on disks that are attached directly to the VMware ESX Host system. With local storage environments, the backup proxy system should be able to communicate with the VMware ESX Host system via the LAN.


Note: The terms SAN/iSCSI are used to denote shared storage between Proxy and VMware ESX Host systems. Wherever SAN is mentioned is also applicable to iSCSI environments where Disks are shared using iSCSI infrastructure.


Supported  transport modes:

VDDK makes  it possible to integrate storage-related applications, including backup, using an API rather than a command-line interface. VMware has developed back-ends that enable efficient access to data stored on ESX/ESXi clusters. Third party developers like CA can access these data paths (called advanced transports) through the virtual disk library. Advanced transports provide the most efficient transport method available, to help maximize application performance.

CA ARCserve supports LAN (NBD), SAN, and HotAdd transport modes using VDDK.

VDDK selects the optimal transport mode

  • NBD /NBDSSL transport mode

  • Advanced transport modes(SAN/HOTADD)

Step 2: Understand backup modes and decide what to use.

CA ARCserve backup provides 5 ways of backup using Agent For Virtual Machines

  • File mode
  • Raw mode
  • Mixed mode
  • Raw mode + 'Allow file level restore'  Enabled (Raw IF)
  • Mixed Mode + 'Allow  file level restore Enabled (Mixed IF)

Step 3:  Components required to be installed.

Required componests to be installed : 

1) CA ARCserve Backup

Install the CA ARCserve Backup Server components on the system that is designated to function as a primary server or a stand-alone server.

2) Agent for Virtual Machines

Install the agent on the system that is designated to function as the backup proxy system. The best practice is to allow the backup server to function as the backup proxy system. However, if you feel that this configuration can impose performance issues on the server, install the agent on a remote system and allow it to function as the backup proxy system.

For information on where to install the agents click here

Note: You must register the agent license on the CA ARCserve Backup server.

3)VMware VCB Framework/VDDK

Ensure that VMware VCB Framework or VDDK is installed on the system that will function as the backup proxy system.

Note: The r16 release of the agent installs VDDK 1.2.1 and the r16 Service Pack 1 release of the agent installs VDDK 5.0. If you want to use the version of VDDK that the agent installs, you do not need to install VDDK.

Step 4:  Deploy Agent for Virtual machines:

Agent for virtual machine can me manually installed or it can be installed using agent deployment.

Procedure to Deploy Agents to Virtual Machines Using Virtual Machine Deployment

Step 5: TCP and UDP Communication ports  required 

Refer to Article - 4511 : Ports used on VMware proxy Server for Agent for Virtual machine

Step 6: Configure the Agent for Virtual machine on the Proxy server.

 Populate the CA ARCserve Backup database using ARCserve VMware Configuration Tool on the backup proxy system. For more information, see Populate the Database Using ARCserve VMware Configuration Tool.

Step 7:  Create a job selecting Backup mode.

The backup mode that you can use to protect VM data is dependent upon the location of where you install the Agent for Virtual Machines.

The backup mode  can be set as Global Options or Local Options

Global backup option--Lets you apply Backup Modes globally to all backup jobs that relate to all VMs in VMware in your environment. For procedure to set global options click here. .

 Local backup option--Lets you apply a Backup Mode to individual VMware instance at the job level overriding the global options. For procedure to set Local Options Click here

Step 8: Enable debug and review the logs if you encounter a problem .

Quickstart ->Job status-> Job History->Expand the job->Expand the failing server

Identify for the exact error message. Search knowledge base for relavent article.

To enable debug for determining  the exact root cause for VM backup failures refer to KB3872.
