In Prism, data protection policies are called protection domains (PDs). A PD is made up of a set of VMs and a policy. The available policies include snapshots, replication locations, and schedules.
VM snapshots
Create a VM snapshot and restore a VM from a snapshot.
In Prism Element > VM, click VM, then click Table.
Locate the Linux VM you created in the previous lab (Linux_VM-intials).
- If the VM is powered on, power it Off
Select the VM, then click Snapshot from the menu below the list of VMs.
Provide a name for your snapshot.
Return to VMs table and click the VM’s name to open its console window.
Click Snapshots to see your snapshot.
- Note the four available actions (Details, Clone, Restore, and Delete).
Click Details to see all of the VM’s properties at the time of the snapshot.
Now lets break our VM.
Click Update from the menu below and modify the original VM you took the snapshot of.
- Scroll down to the disks section and delete the CD-ROM and DISK by clicking the X icon for each item.
- Click Save to finalize the changes.
Now attempt to power on that VM and open its console window.
- Note that the VM no longer has any disks to boot from and that the 2048 game is displayed.
Power off the VM.
Select the VM, then click VM Snapshots from the menu below the list of VMs.
Click Restore to revert the VM to the state it was in before you removed the disks.
Attempt to power on the VM and open the console.
Verify that the VM boots successfully and that its configuration has been restored.
Configure a Protection Domain (PD)
In Prism Element > Data Protection, click Data Protection, then click Table.
Click + Protection Domain to create a PD, then click Async DR.
Provide a name for the PD, and click Create.
Select the VMs that you want be members of the PD:
- Filter or scroll to select the VMs you created in this bootcamp to be part of the PD.
- Scroll down and click Protect Selected Entities.
- The selected VMs appear in the right-hand side table. Click Next.
Configure a local schedule:
- Click New Schedule.
- Select a frequency (for example, repeat every one day).
Configure a retention policy:
- Set the retention policy (for example, keep the last two snapshots).
Note
Local is the only option in this lab environment because no remote targets are configured.
You could setup a remote site with a neighbor cluster.
Click Create Schedule.
Note
A Protection Domain can have multiple schedules.
Click Close to exit.
