 Introduction 

As a part of backup infrastructure implementation, using GCP (Google Cloud Platform) shared VPC’s (Virtual Private Cloud) to come up with multi-NIC media agent setup for CommVault infrastructure. This opened doors to backup data from one tier and restore the same across another tier. This has reduced the overall time and cost to migrate data to a separate  client over the GCP network. It also ensured that there is network isolation between production and non-production tiers as no additional firewall ports had to be opened to transfer the backups.

Media agent in GCP with two VPC’s

Below is the screenshot from GCP console which shows Commvault media agent has two NIC’s associated with different subnets from two separate shared VPC’s.

Restore using Commvault multi-NIC media agent

Below is a high level diagram showing the refresh between production and non-production tiers (segregated across VPC’s) by using Multi-NIC media agent. Media agent will read data from storage bucket by using production interface and restore it to required client by using non-production interface.

Once you finalize the backup you want to restore, get the details of source and destination clients.

Source Client

Source zone

Destination client

Destination zone

Media agent
