vRanger 7.8.5 - Installation/Upgrade Guide

Introduction Before you install System requirements and compatibility Installing vRanger Upgrading vRanger

Considerations for installing vRanger in a VM

Read the following notes regarding limitations and considerations about installing vRanger in a VM:

In recent versions of Windows®, volumes are recognized by a serial number assigned by Windows. When VMs are cloned, the serial number for each VM volume is cloned as well. During normal operations, this cloning is not an issue; however, when vRanger is cloned from the same source or template as a VM being backed up, the vRanger volume has the same serial number as the source volume.

Installing vRanger on a physical server

Installing vRanger on a physical server provides a method to off-load backup resource consumption from the VMware® ESXi™ host and network. While you can perform Machine-based LAN in this configuration, LAN-free backups are the primary driver for using vRanger in a physical server. For more information, see LAN-free backups (VM backups only) and LAN backups.

Available transports

The transports available when vRanger is installed in a physical machine include the following:

LAN-free backups (VM backups only)

With vRanger installed on a physical machine, you may perform LAN-free backups with either the VA-Based HotAdd or Machine-based SAN transports.

VA-based HotAdd: This transport mounts the source VM’s disk to the vRanger VA deployed on the source host or cluster. This method allows vRanger — through the VA — to have direct access to the VM data through the VMware® I/O stack rather than the network. In this configuration, data is sent directly from the VA to the repository.
Machine-based SAN: This transport option uses your fibre-channel infrastructure or iSCSI network to transport backup data to the vRanger machine.

With vRanger installed on a physical server, the following configurations must be made:

Click Start > All Programs, and enter diskpart.
Run the automount disable command to disable automatic drive letter assignment.
Run the automount scrub command to clean any registry entries pertaining to previously mounted volumes.
Only one vRanger server should see a set of VMFS LUNs at one time. For backups only, The vRanger server should have only read-only access to the LUNs. To perform LAN-free restores, ensure that the vRanger server has Read + Write access to any zoned VMFS LUNs to which you want to restore.
