How to setup OLVM backup over storage network?

If your Oracle Linux Virtualization Manager (OLVM) has existing storage network, you could choose to run VM backups over storage network, this can eliminate the impact on production network during the backup process.

To setup OLVM backup over storage network, it only requires Vinchin backup server has 2 network interfaces. One of the network interfaces connects to the management network, the other connects to the storage network.

For detailed configurations, please follow the steps below.

Step 1: Network connection

Make sure there are at least 2 network interface cards on the Vinchin Backup Server. One of the network interface cards connected to the management network, another connected to the storage network.

Warning

If your Vinchin Backup Server is already licensed, adding new network interface card to the server will invalid the license. If you have to do so, please contact Vinchin support before you proceed.

Step 2: Install Vinchin backup plugin for OLVM

Download Vinchin backup plugin for OLVM from the login screen of Vinchin backup server web console. By clicking on the Download Backup Plugin and then select the OLVM version to download.

Upload the downloaded backup plugin installation file to each of the OLVM hosts, then run the below commands from each of the OLVM hosts’ CLI to install.

In the above commands, where “6.0.0-10468” should be the actual version number of the backup plugin you downloaded.

Note:

Please DO NOT install backup plugin on OLVM Engine.

Step 3: Change Vinchin backup plugin listening IP

Edit Vinchin backup plugin conf file from OLVM host CLI by using below command.

Modify the listening IP of backup plugin from 0.0.0.0 to the IP of the OLVM host network interface which is connected to the storage network.

For example, the OLVM host got an IP 172.16.0.100 which is connected to management network, another IP 10.10.10.100 which is connected to storage network, please change the listening IP to 10.10.10.100.

The modification should be done on all the OLVM hosts, and the listening IP should be corresponding to each of the OLVM hosts’ storage network IP respectively.

Step 4: Restart backup plugin services

Restart Vinchin backup plugin services for OLVM using the command below.

Step 5: Add OLVM to Vinchin backup server

Open Vinchin backup server web console, add OLVM to Vinchin backup server under Resources > Virtual Infrastructure.

Please add OLVM by using the IP/domain of the OLVM engine and admin (with internal domain) user credentials.

Step 6: Create VM backup job

Create a VM backup job under VM Backup > Backup, follow the New Backup Job wizard to complete the job settings.

In the 3^rd step – Backup Strategy, under Transmission Strategy tab, please select LAN in the Transfer via dropdown list.

With the above configurations, the VM backups will be transferred through the storage network.
