Before you start deploying Veeam Backup for RHV, make sure the RHV environment and the backup infrastructure components meet the following requirements.
Kernel-based Virtual Machine (KVM) must be installed on x86 hardware that supports virtualization capabilities.
Veeam Backup for RHV is compatible with Red Hat Virtualization version 4.4 SP1 only (Red Hat Virtualization manager version 4.5.0 or later).
Veeam Backup & Replication version 18.104.22.1680 with RHV Plug-in version 22.214.171.1241 (or later) must be deployed on the backup server.
The RHV backup proxy must be provided with sufficient compute resources to handle backup and restore tasks in parallel. The maximum number of concurrent tasks is configured in RHV backup proxy settings. If this number is exceeded, the backup proxy will not start a new task until one of the current tasks finishes.
The default RHV backup proxy configuration has the maximum number of concurrent tasks set to 4 and includes the following compute resources:
While deploying a new RHV backup proxy or editing settings of an existing one, you can increase the maximum number of concurrent tasks. However, you must allocate 1 vCPU and 1 GB RAM for each additional task. When configuring the maximum number of concurrent tasks, you must also take into account the network traffic throughput in your virtual infrastructure.
