Recovering data using NetBackup to on-premises data center
Using Resiliency Platform console, you can recover VMware virtual machines that are protected by NetBackup and managed using a service objective where the data availability mode is Copy.
You can choose from the most recent successful backup image or another available backup image.
You can recover data on VMware virtual machines in the same data center or in a remote data center.
A virtual machine is recovered using the selected backup image at selected data center, which could be the same data center or a remote data center. Before that, the virtual machine whose data is being recovered is stopped and unregistered. Virtual machines are unregistered only if the recover is on a remote data center.
The network settings of the virtual machine are configured as per the subnet mapping, switch or port mapping as specified during the configure for remote recovery operation. Finally the virtual machine is up and running at the recovery/selected data center.
The state of the virtual machine is Deleted/Unavailable.
If a virtual machine is deleted, you can choose the latest backup copy or any previous backup to recover the virtual machine on the required data center.
After configuring a resiliency group for recovery using a service objective where the data availability mode is Copy, it might take some time for the backup images to reflect in the Recover wizard.
When you choose the Local recovery of hosts service objective, then during the recover operation remote data center is not displayed. Using this service objective you can choose the virtual machines whose data you want to recover irrespective of the number of virtual machine in the resiliency group.
For Local and remote recovery of hosts service objective, if virtual machines are registered in the target data center, then recover is of the type local. If virtual machines are not registered in the target data center, then the recover is of the type remote.
After the recover operation is successfully completed, you may refresh the NetBackup primary server to discover new backup policies. Or you may wait for the scheduled discovery to complete.
Consider the following before running the recover operation:
If a virtual machine is already present on the recovery site and is online, then the data on the virtual machine is not overwritten during the recover operation.
If the virtual machine is registered but in offline state, then the virtual machine is deleted. A new virtual machine is created and the backup image is restored on that machine.
If the virtual machine is present in the inventory but not registered, then the virtual machine is deleted. A new virtual machine is created and the backup image is restored on that machine.
If the virtual machine is not registered and is not present in the inventory, then a new virtual machine is created and the backup image is restored on that virtual machine.
A successfully recovered image is tagged. Hover the mouse on the tag to view additional information such as the NetBackup primary server name, the image type (full or incremental), and the last test date and time.
To recover virtual machine data using copy based recovery
- Prerequisites
The resiliency group that contains the VMware virtual machines must be protected using the service objective activated for copy based recovery.
The IMS, ESX server/ clusters, and the vCenter on the recovery data center must be connected to the NetBackup primary server.
Ensure that the state of NetBackup primary server is Connected which means that the notification channel is working.
- Navigate to Assets (navigation pane) > Resiliency Group(s) tab.
- Go to the details page for the resiliency group with the virtual machines that you want to recover and select Recover.
- In the Recover Resiliency Group panel do the following and click Next.
Select one of the data centers for local recovery or remote recovery. The recover operation would be performed based on the data center selected.
Note:
If the resiliency group is created using Local recovery of hosts service objective, only Local data center is shown as target data center.
Select Latest or Time Range options for recovery points.
You can choose from the latest image or any other available backup from the specified time range. To choose from a specific time range, select the date and the time range. Then select the hours or minutes since the start time.
Click Submit.
Note:
While creating a resiliency group, if you have added multiple virtual machines with multiple policies which has different Media Servers and different recovery host than current one, the restore jobs may fail with the error - Access to the client was not allowed. Hence, you need to add Primary server as recovery host or add different resiliency groups for different policies and create VBS for it and perform the recovery.
Use (bottom pane) > to view the details of this task in a graphical representation.
On successful completion of the recover operation, verify that the selected virtual machines are online.
While performing the recover operation, outage flag (if any) is cleared implicitly and backup images are restored to the intended data center.
If you clone a VMware virtual machine that was recovered by Resiliency Platform, change the MAC address assignment mode for all the NICs of cloned virtual machine to automatic. This should assign new MAC address to NIC of cloned virtual machine and should avoid duplication of MAC addresses.
