Overview

This article describes prerequisites and configuration requirements for SEP sesam integration with Hyper-V. Note that the procedures introduced in this article are only the required configuration steps. For details on backup configuration, see Hyper-V Backup.

Prerequisites

• Hyper-V Server 2016/2019 or Hyper-V Server 2012/R2
• SEP sesam Client version ≥ 4.4.3. Grolar.
  Note that a hyperv_import.dll is missing in SEP sesam Windows Client version 4.4.3 Tigon V2 (4.4.3.48), which causes Hyper-V restore – import to fail. Therefore it is recommended to upgrade the SEP sesam Server and Client to the latest version during the regular upgrade process. For details, see Updating SEP sesam.
• Working name resolution for Hyper-V nodes and the Hyper-V resource (for Hyper-V cluster).
• SEP sesam backup client package must be installed on a Hyper-V standalone server or, in case of a Hyper-V cluster, on each node in the cluster. See section Automatically installing SEP sesam Client on all Hyper-V cluster nodes.
• For each Hyper-V node in the cluster, make sure that the SEP sesam service is running with the rights of an Active Directory (AD) user with domain administrator role (for Hyper-V cluster).

Configuring a Hyper-V standalone server or cluster as a SEP sesam Client

To protect your Hyper-V virtual machines, you must configure the Hyper-V server (for Hyper-V standalone server) or Hyper-V resource (not the physical Hyper-V nodes for Hyper-V cluster) as a SEP sesam Client. For details, see Configuring Clients.

1. From Main Selection -> Components -> Topology, select your location and click the New Client button. The New Client window opens.
2. In the New Client window, configure the following options:
   • Enter the Name of your Hyper-V client.
   • Select Windows from the Platform drop-down list and the relevant Windows version under Operating system.
   • Choose the Access mode for the SEP sesam Server-Client communication (the default setting is SMSSH, previously CTRL).
   • From the VM server type drop-down list, select Hyper-V-Server (for Hyper-V standalone server) or Hyper-V-Cluster (for Hyper-V cluster).

   

   
   
3. As of v. 4.4.3 Beefalo, you have to enter the credentials as an administrator to access the respective systems under the OS Access tab. Use DOMAIN\USER format for domain accounts or HOST\USER for local accounts.

	Note
	Specifying OS is especially important when configuring a client for Hyper-V cluster. If they are not set, the Hyper-V client update will fail, as described in the section Updating Hyper -V cluster client.




4. Click OK to add the new client.

Automatically installing SEP sesam Client on all Hyper-V cluster nodes (Windows only)

Automatic installation of the SEP sesam Client on all Hyper-V cluster nodes is available for Windows SEP sesam Server only. If you are using a Linux SEP sesam Server, you have to manually install the SEP sesam Clients on the Hyper-V nodes.

	Note
	If you are still using SEP sesam Client version 4.4.3 Tigon V2 (4.4.3.48) on Windows cluster nodes, you should upgrade the SEP sesam Server and Client to the latest version during the regular upgrade process. 4.4.3 Tigon V2 (4.4.3.48) is no longer supported by SEP sesam and had issues with Hyper-V restore. For details on the issue, see 4.4.3 Tigon V2 (4.4.3.48).

1. Copy the client installation package sesam-cli-4.4.3.XX-windows.x64.exe to the <SEPsesam>\var\work\packages folder on the SEP sesam Server.
2. Open the Command Prompt in your Windows SEP sesam Server as an administrator: Type cmd into search, right-click the displayed Command Prompt option and select Run as administrator.
3. Once the Administrator: Command Prompt window is opened, use the following command to install the SEP sesam client onto the Hyper-V cores. Note that the inserted [domain\]user must be a domain administrator with access to all Hyper-V nodes.
sm_config_client -I cli -c <clientname> -u <[domain\]user> -p <password> Example cd "C:\Program Files\SEPsesam\bin\sesam" sm_config_client -I cli -c HyperVresource -u SEP\mm -p supersecret

The SEP sesam Client is installed on each Hyper-V core. If the Hyper-V cluster has four Hyper-V cores, the SEP sesam Client will be installed on all four Hyper-V cores. The Hyper-V nodes will be added to the same location as your Hyper-V resource as additional SEP sesam Clients with the state locked for backups (no licence required). To have all your data protected, do not delete the clients.

Once your Hyper-V standalone server or cluster is added as a SEP sesam Client, create backup tasks for each VM, as described in Hyper-V Backup.

Updating Hyper-V cluster client

When the Hyper-V cluster client is updated (by right-clicking the client in the Clients window and selecting Update Client), all cluster nodes within the Hyper-V cluster resource are automatically updated.

Before you update a Hyper-V cluster client, ensure that the OS credentials are specified for that client. This allows the Hyper-V cluster resource to automatically update all cluster nodes within the Hyper-V cluster. Otherwise, the update fails and an error is displayed in the Topology -> Update State column.

If not already specified when configuring the Hyper-V cluster client, you can specify the credentials at any time in the client properties; double-click the Hyper-V cluster client to open its properties, switch to the OS Access tab, and specify the required credentials.
