Before you start deploying Veeam Backup for Nutanix AHV, make sure the Nutanix AHV cluster and backup infrastructure components meet system requirements listed below.
AHV Backup Proxy supports the following versions of the Nutanix AOS:
- Nutanix AOS versions 5.5.x up to 6.0.x
- Community Edition: CE 2019.11.22 or later
To integrate the AHV cluster with Veeam Backup for Nutanix AHV, you must define an IP address for iSCSI data services in settings of the AHV cluster. For instructions, see the Modifying Cluster Details section of the Prism Web Console Guide.
Virtual Hardware for AHV Backup Proxy VM
During the deployment process, AHV Backup Proxy is deployed as an independent Linux-based VM on a Nutanix AHV cluster that you want to protect. The AHV Backup Proxy VM must meet the following requirements.
- CPU: x86-64 processors. 4 CPU cores plus 1 CPU core for each additional concurrent task.*
- Memory: 4 GB RAM plus 1 GB RAM for each additional concurrent task.*
- Disk Space: 1 GB for product installation.
*AHV Backup Proxy creates one task per every VM processed by the job. CPU and hardware resources for the AHV Backup Proxy VM are calculated automatically based on specified number of concurrent tasks. VMs with multiple CPU cores can handle more concurrent tasks. For example, for 4 concurrent tasks, it is recommended that you specify minimum 4 CPU cores and 4GB RAM, for 8 concurrent tasks — 8 CPU cores and 8 GB RAM. When defining the number of concurrent tasks, keep in mind the network traffic throughput in the virtual infrastructure.
Veeam Backup & Replication and Nutanix AHV Plug-in
As described in Backup Infrastructure Components, Veeam Backup for Nutanix AHV consists of 3 main components: AHV Backup Proxy, Nutanix AHV Plug-in and Veeam Backup & Replication.
If you want to install Nutanix AHV Plug-in or upgrade backup infrastructure components, mind the following:
- AHV Backup Proxy 2.1 supports integration with Nutanix AHV Plug-in 2.1 installed on the Veeam Backup & Replication 11 server.
- AHV Backup Proxy 2.1 also supports integration with Nutanix AHV Plug-in 2.0 installed on the Veeam Backup & Replication 10 server. This combination of product versions is related to the case when you want to upgrade to AHV Backup Proxy 2.1 but don’t want to upgrade to Veeam Backup & Replication 11. In this case, you can upgrade AHV Backup Proxy in the web console and continue using Veeam Backup & Replication 10 and Nutanix AHV Plug-in 2.0. For detailed instructions on how to upgrade to version 2.1, see Upgrading from Version 2.0 to 2.1.
- You cannot install Nutanix AHV Plug-in 2.1 on the Veeam Backup & Replication 10 server as this configuration is not supported.
The hostname of the Veeam Backup & Replication server must be resolved on the AHV Backup Proxy VM. Otherwise, AHV Backup Proxy cannot connect to Veeam Backup & Replication. The issue is also valid if AHV Backup Proxy is running behind NAT.
