Creating an alias for a Hyper-V cluster

To work around a Microsoft limitation that prevents the Unitrends appliance from running simultaneous backups of clustered VMs hosted on a server running Windows 2008 R2, you can create a client alias for each cluster shared volume (CSV) using the procedure described below. After adding each client alias to the appliance, you can create a backup schedule for each CSV and backups of the clustered VMs can run concurrently.

To create a client alias for a Hyper-V cluster

1        Log in to the appliance to which the cluster is added.

2        Select Settings > Clients, Networking, and Notifications > Networks > Hosts.

3        Click on the client name in the table.

4        Type a name in the Alias Name field. It is recommended that you include the CSV number in the name to help you remember which CSV you would like to associate with each alias.

Note: Do not enter spaces in the name. You are limited to 15 characters. It is recommended that you write down the alias name so you can enter the exact name when you add it as a new client.

5        Click Add. You see the alias name in the Alias List area.

Note: To remove an alias name from the Alias List area, click on the alias name and click Remove. To remove all alias names from the Alias List area, click Remove All.

6        Repeat to add more alias names, if necessary.

7        Click Confirm.

To add the alias name as a client

8        Go to Settings > Clients, Networking, and Notifications > Clients.

9        Click Add Client. You see the Add Client screen.

10    Select Hyper-V from the Computer Type drop-down list.

11    Uncheck Establish trust in the Authentication area.

12    Uncheck Automatically create a backup schedule for this computer and apply it immediately in the Options area.

13    Enter one of your new alias names in the Computer Name field.

Note: There is no need to add an IP address, since this defaults to information from the host page.

14    Click Setup. You see a processing message, then a Reload Navigation window describing that you need to refresh the system.

15    Click Yes, reload the System or No, reload the System later.

16    After you reload the system, the new alias name displays in the Navigation pane in the list of clients protected by the system.

17    Repeat as needed to add additional client aliases.

18    See To execute an immediate Hyper-V backup or To create a Hyper-V backup schedule to run backups for the clustered VMs. When scheduling backups, create a separate schedule for each alias.
