Using AWS snapshot replication
This section elaborates how to create snapshot replicas using the AWS snapshot replication feature, and restore the replicated snapshots whenever required. Refer to the NetBackup™ CloudPoint Install and Upgrade Guide and the NetBackup Web UI Administrator's Guide for details about these steps, otherwise indicated.
This section describes how to configure the Source region to create snapshot replicas in the Target region.
To create replicas
- Add CloudPoint server (CP1) in webUI. Add a CloudPoint server
- Add AWS plug-in for Source and Target region for replication.
- Create protection plan and select Region and Account.
- Connect and configure an application consistent guest VM using the OnHost agent.
- Trigger snapshot-based backup and replicate the snapshots using the protection plan.
- Verify the recovery points for snapshot and replica copy.
If the Source region fails, you can restore the VMs belonging to this region, from the Target region, where you have taken the snapshot replicas. As the Source region is down, you will initially need to restore the VMs in the Target region.
Note:
You cannot restore single files or folders from a replica that was discovered by an alternate CloudPoint server in a failed over region.
Restoring in the target region
- Disable server CP1 in the Source region from webUI. Enable or disable a CloudPoint server
- Register a new CloudPoint server (CP2) in the target region, from webUI.
- Add AWS plug-in for only the Target region and account. Let the discovery complete.
- To restore VMs:
Log on to the NetBackup console.
On the left, click Cloud, under Workloads. On the Virtual machines tab, click the machine that you want to recover.
Click the Recovery points tab. In the list of images, click Restore in front of the required Replica image, and click Restore virtual machine.
To change the Display name for the VM, enter a new name.
Select a subnet (subnet path having VPC).
- Add appropriate security group to the restored VMs to enable remote access.
- Uninstall and reinstall the CloudPoint agent from the restored VMs, and then register the CloudPoint agents with the new CP2 server.
- Run a deep discovery from the AWS provider console.
- Create new protection plan to protect the restored VMs. Trigger a snapshot-based backup.
You can restore the VMs from the Target region to the Source region, once the source region is back online.
Restoring to the source region
- Edit the AWS plug-in for CP2 and add the Source region.
- Create a new protection plan to create a snapshot replica in the Source region.
- Trigger snapshot-based backup and replicate.
- Disable the CP2 server in webUI. Enable or disable a CloudPoint server
- Enable the CP1 server and trigger deep discovery from AWS provider console.
- Perform full restore of the VMs from the Target region.
- Add appropriate security group to enable remote access to restored VMs.
- Uninstall and reinstall the CloudPoint agents from the restored VMs, and then register CloudPoint agents with the CP1 server.
- Run a deep discovery from the AWS console.
- Use the existing protection plan to protect newly restored VMs.
