Recovering Snapshot Manager virtual machine
.
From version 10.1, the HA is enabled by default. The snapshot of the Snapshot Manager server is taken once in a day and the snapshot is stored in the same resource group. These stored snapshots can be used for recovering or upgrading the Snapshot Manager. The Snapshot Manager will be deployed in a virtual machine scale set.
Once you identify the snapshot in the cloud, you can follow the steps mentioned below.
Recovering Snapshot Manager using Azure Marketplace deployment
- In this case, the Snapshot Manager is deployed on a VM Scale Set (VMSS) and regular snapshots of Snapshot Manager are taken once daily and snapshot copies are maintained up to last 3 days.
If you want to recover from the latest Snapshot Manager Snapshot:
Delete the Snapshot Manager instance in the VMSS which you want to recover. This would automatically create a new Snapshot Manager instance in the VMSS which would have the Snapshot Manager data disk, created from the latest snapshot (backupsnapmgr*).
If you want to recover from an older Snapshot Manager Snapshot:
a. Create a disk from the Snapshot Manager Snapshot you want to recover.
b. Note the operating system of the Snapshot Manager VMSS.
c. Stop the existing Snapshot Manager VMSS. While stopping the VMSS, select the option to reserve the public IP address, if associated.
d. Disassociate the public IP address of the Snapshot Manager VMSS, if associated and note the IP address name.
e. Note the VMSS name and delete the Snapshot Manager VMSS.
f. Launch the Veritas NetBackup cloud marketplace deployment in Azure.
g. Select the Snapshot Manager only deployment.
h. Select the same Resource Group and Region as that of the older Snapshot Manager deployment.
i. Use the same Snapshot Manager VMSS name as that of the older Snapshot Manager VMSS. This is the same VM name as noted in step e.
j. Use the existing DNS zone name, which was used in the original Snapshot Manager deployment.
k. Select the same OS as that of the older Snapshot Manager VMSS that was noted in step b.
l. Select Yes for the Upgrade from an existing Snapshot Manager instance option.
m. Provide the disk name created from snapshot in step a.
n. Perform the deployment in the same Virtual Network and subnet as that of the older Snapshot Manager VMSS.
o.. Assign the same public IP, if there was any IP address associated earlier and was dissociated in step d.
p. Click Review and create to start the Snapshot Manager upgrade process.
