vRanger 7.8.4 - Installation/Upgrade Guide

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

Bandwidth to repositories

While performance varies based on environmental factors, data throughput during a single backup task can reach up to 100 MB/s. If you assume a standard case of a repository connected by using a Gigabit network, as little as 10 concurrent jobs can saturate the link to that repository.

Although there is no ability to throttle data transmissions from a source server, vRanger can limit the number of simultaneous backup tasks on a per-repository level.

 
* 
NOTE: This configuration is a global configuration, meaning that it applies to all repositories.

Repository size

There is no limit to the number of savepoints that can be stored in a vRanger repository. There are, however, environmental limits on the size of a single directory. The available options, and their limits, are described in the following list.

 
* 
NOTE: The volume limitations described in this topic are limitations within the Windows® environment.
•
Default configuration: A standard volume, with an MBR partition on a basic disk, has a limit of 2 TB. This configuration is the default for Windows Server® 2003. In this configuration, the vRanger repository cannot exceed 2 TB.
•
Dynamic disks: Dynamic disks contain dynamic volumes, including simple volumes, spanned volumes, striped volumes, mirrored volumes, and RAID-5 volumes. A repository on dynamic disk volumes can be as large as 64 TB.
•
GPT volumes: GUID partition table (GPT) volumes provide a more flexible mechanism for partitioning disks than the older Master Boot Record (MBR) partitioning scheme that has been common to PCs. GPT partitions are supported on Windows Server 2003, SP1 and later, and can reach up to 256 TB. For more information, see http://www.microsoft.com/whdc/device/storage/GPT_FAQ.mspx

Configuring vCenter permissions

vRanger requires a VMware® vCenter™ account to function properly. To comply with security best practices, Quest recommends creating a vCenter user account with the minimum required permissions for vRanger to use.

To create a vRanger user on vSphere 6 or later:
1
Navigate to Administration > Roles.
2
Select Add Role.
3
Enter a name for the role, such as vRanger Non-Admin.
4
In the Privileges section, set the permissions according to the following table:

Navigate to the Inventory view.
6
Right-click the applicable level to grant user permission, such as the main vCenter level, and click Add Permission.
7
Add and locate the applicable user account, select the recently created User Role, and click Add.
8
Click OK.
 
* 
NOTE: When you add the vCenter to the vRanger inventory, use this account for authentication.

 

System requirements and compatibility

Requirements for the vRanger machine

To maximize application performance, and to ensure error-free operation, you must ensure that the machine on which vRanger is installed meets the requirements as documented in this topic.

Requirements for the vRanger machine are divided among these topics:

•
Minimum hardware requirements
•
Supported operating systems for installation

Review each of these topics thoroughly before installing vRanger.
