Unitrends appliance version
|
The Unitrends appliance must be running version 10.2 or higher.
The Unitrends appliance must be running an Enterprise or Enterprise Plus license.
|
Nutanix AHV host cluster version
|
The AHV host must be running Acropolis Operating System (AOS) version 5.1.4 or a higher version supported version listed in the Unitrends Compatibility and Interoperability Matrix.
|
AHV host account privileges
|
While adding the AHV cluster to the Unitrends appliance (described in To add a virtual host asset), you must enter the username and password credentials of one of the following AHV cluster accounts:
|
•
|
The Nutanix cluster admin account – You must use this account if the AHV cluster is not configured to use directory services authentication and the cluster is running a pre-5.5 AOS release. Other user accounts with full administrative privileges are not supported. |
|
•
|
Any local Nutanix cluster account that has been assigned the user admin or cluster admin role – Use a local account with either of these roles if the AHV cluster is not configured to use directory services authentication and the cluster is running AOS release 5.5. |
Requirements for directory services authentication in AOS 5.1
These additional requirements apply to Nutanix AHV clusters running in AOS 5.1 that are configured to use directory services authentication:
|
–
|
In the Directory List, add a new directory of type Active Directory and connection LDAP. For the Directory URL, specify ldap://<ip-address>:<port> |
|
–
|
Create a role mapping for the LDAP user and assign the cluster admin role. |
|
–
|
In the self service portal (SSP), set or update the SSP administrators to the user@domain. Use fully qualified domain names. |
|
–
|
SSP will need to query the active directory for details of users. Ideally a service account with no time limit should be used. This account must have privileges for listing the users in the Directory server. |
|
•
|
While adding the AHV cluster to the Unitrends appliance (described in To add a virtual host asset), you must specify a domain in addition to the username. The username and domain are case sensitive. Be sure to match the case that was entered in the self service portal (SSP). In the Username field, enter the username and domain in this format: user@domain. For example, jalvarez@unitrends.com |
Requirements for directory services authentication in AOS 5.5
These additional requirements apply to Nutanix AHV clusters running in AOS 5.5 that are configured to use directory services authentication:
|
–
|
In the Directory List, add a new directory of type Active Directory and connection LDAP. For the Directory URL, specify ldap://<ip-address>:<port> |
|
–
|
Create a role mapping for the LDAP user and assign the cluster admin role. |
|
•
|
While adding the AHV cluster to the Unitrends appliance (described in To add a virtual host asset), you must specify a domain in addition to the username. In the Username field, enter the username and domain in this format: user@domain. For example, jalvarez@unitrends.com |
|
iSCSI target access
|
AHV backup and recovery jobs access the AHV host over the iSCSI protocol.
Ensure the following:
|
•
|
The Unitrends appliance is able to connect to the iSCSI targets on the Nutanix storage LAN. |
|
•
|
iSCSI Data Services are configured for the Nutanix AHV cluster. To configure this setting: |
|
1
|
In the Nutanix Prism interface, select Cluster Details from the Options menu. |
|
2
|
Enter the iSCSI Data Services IP address. |
|
Virtual machine storage
|
The following requirements apply to virtual machine storage:
|
•
|
Virtual machine storage must be disk storage allocated on a storage container. VM disks that are attached to a Volume Group are not included in the backup. |
|
•
|
Host-level protection is not supported for independent and pass-through disks. To protect these disks, you must install a Unitrends agent and use file-level backups instead. |
|
Virtual machine configuration
|
The following VM configuration requirements must be met for Unitrends host-level protection:
|
•
|
Nutanix recommends installing Nutanix Guest Tools (NGT) in the guest operating system to ensure file system and application consistency. |
|
•
|
NGT tools must be installed and running to enable application consistent quiesce. If NGT is not running, crash consistent quiesce is used. For details, see this Nutanix document: Nutanix Guest Tools. |
|
•
|
For Windows guests, Nutanix recommends installing VirtIO drivers for enhanced performance and stability. For details, see this Nutanix document: Nutanix Virtio for Windows. |
|
Virtualized Active Directory servers
|
To ensure database consistency, you must set up the virtualized Active Directory (AD) server in accordance with Microsoft best practices. If all Microsoft considerations are not addressed, backup and restore of the virtual machine may yield undesired results. If you prefer not to research these best practices, install the agent on the VM and protect it as you would a physical server (leveraging Microsoft’s VSS writers).
|
Distributed File System environments
|
Distributed File System (DFS) Namespaces and DFS Replication offer high-available access to geographically dispersed files. Because of the replication and syncing operations in DFS environments, you must set up the virtual machine in accordance with Microsoft best practices to ensure database consistency. If all Microsoft considerations are not addressed, backup and restore of the virtual machine may yield undesired results. If you prefer not to research these best practices, install the agent on the VM and protect it as you would a physical server (leveraging Microsoft’s VSS writers).
