Configuration for Microsoft Hyper-V IntelliSnap

Enable IntelliSnap

IntelliSnap protection is enabled through Advanced configuration on the virtualization client properties and the IntelliSnap Operations tab on each subclient's properties. The Enable IntelliSnap option on the client provides the ability to configure IntelliSnap operations for any subclient; the subclient properties configuration identifies the Snap engine and the Hyper-V proxy host that can be used to mount snapshots.

Storage policy configuration enables you to create a Snapshot Copy and enable Backup Copy operations for snapshots.

Understanding the CommCell Console

The Virtual Server Agent uses three main components to perform backup and restore operations from the CommCell Console.

  • Virtualization Client - A logical entity that provides a single point of administration for Hyper-V servers hosting virtual machines to be backed up.

  • Subclient - A logical entity that identifies a set of virtual machines to be backed up.

  • Backup Set - A group of subclients defining data to be backed up by the agent.

Protecting Migrated Virtual Machines

The backups for a Hyper-V cluster can be configured so that the data in the cluster is seamlessly backed up, and incremental backup cycles are maintained, even if virtual machines migrate from one host to another (live migration). For example, if the next scheduled backup after a live migration is an incremental backup, the incremental backup is performed for the migrated virtual machine, not a full backup.

Create a Virtualization Client

You must install the Virtual Server Agent on all Hyper-V servers in a cluster.

To create a client for a cluster:

  1. From the CommCell Console, right-click Client Computers and click New Client > Virtualization > Microsoft Hyper-V.

  2. Enter the Client Name.

    You can enter the Hyper-V cluster name or any other name to identify the group of Hyper-V nodes. Do not use the host name of an existing client.

  3. Enter the credentials required to access the Hyper-V cluster. These credentials must be valid for all nodes in the cluster.

  4. Click Add to identify the nodes of the Hyper-V client.

  5. From the Exclude list, select all Hyper-V hosts as the nodes of the Hyper-V client.

    The list displays all computers that have the Virtual Server Agent installed.

    When you select all hosts in the failover cluster as nodes in the Hyper-V client, a virtual machine can be migrated to any host in the failover cluster and will still be included automatically in the next backup job. All virtual machines on all nodes will be protected, regardless of the hosts that they are actively running on.

  6. Click Include and click OK.

  7. Review the Client /Client Groups list.

    • Hyper-V nodes are selected to perform backup operations based on their sequence in the Client /Client Groups list (nodes are selected from the top of the list first).

    • You can change the position of a node by selecting the node and clicking the up or down arrow.

    • The first node serves as a coordinator proxy.

    • You can specify up to 16 proxies for each Hyper-V instance.

  8. Click OK.

Add or Remove Hosts for an Existing Client

To add or remove hosts from the cluster:

  1. From the CommCell Console, navigate to Client Computers > virtualization_client > Virtual Server > Hyper-V.

  2. Right-click Hyper-V, and select Properties.

  3. Click the Nodes tab.

  4. To add hosts:

    1. Click Add.

    2. Select a node from the Exclude list, and then click Include.

      You can also select more than one node from the Exclude list. This list displays all Hyper-V servers that have the Virtual Server Agent installed.

    3. Click OK.

  5. Review the Client /Client Groups list.

  6. To remove any node from the list, select the client name for the node, and then click Remove.

    Note

    When you remove a node from the Microsoft Hyper-V client, any virtual machines from that Hyper-V server will not be included in the backup. If you have set up the Microsoft Hyper-V client for a failover cluster, do not remove any hosts from the list of nodes.

  7. Click OK.

Configuring a Client for a Standalone Hyper-V Server

When you want to backup the virtual machines on a standalone Hyper-V server, you must install Virtual Server iDataAgent on the Hyper-V server. When you install the Virtual Server iDataAgent on any Hyper-V server, it appears as a client in the CommCell console. However, you can not use it to perform the backups. You must configure the client to perform backups for the standalone Hyper-V server. Follow the steps given below to set up a client for a standalone Hyper-V server:

Procedure

The Virtual Server Agent must be installed on the Hyper-V server.

  1. From the CommCell Console, right-click the Client Computers node and click New Client > Virtualization > Hyper-V.

  2. Enter the client name of the Hyper-V server in the Client Name box.

    A client name is the Communication Interface Name, selected during the Virtual Server iDataAgent deployment. By default, the client name is same as network interface name.

  3. Enter credentials required to access the Hyper-V server.

  4. From the Storage Policy list, select a storage policy to associate with the virtualization client.

    The storage policy you select is also associated with the default subclient that is created automatically for the virtualization client.

  5. Click Add.

  6. From the Exclude list select the Hyper-V server.

  7. Click Include and click OK.

  8. Click OK.

A Hyper-V instance and a defaultBackupSet is automatically created on the client. The default subclient in the defaultBackupSet is automatically configured to back up all the virtual machines on the standalone Hyper-V server.

Automatically Adding Unprotected Virtual Machines to the Default Subclient

By default, all the virtual machines from a Hyper-V Cluster are automatically included in the default subclient of any backupset. This behavior is designed to ensure all virtual machines are backed up. However, following virtual machines will be excluded from the default subclient:

  • Virtual machines which are included in a user defined subclient. This will avoid the duplicate backup of any virtual machine.

  • Virtual machines on the Hyper-V server where Virtual Server iDataAgent is not installed.

  • Virtual machines excluded by filters defined for the default subclient.

We recommend that in a Hyper-V instance, do not modify these settings for all default subclients. At least one default subclient must have the capability to serve as a catch-all entity for Hyper-V data. If you disable this feature for all the default subclients, some data in the Hyper-V Cluster may not get backed up.

If you do not want all virtual machines to automatically be included in the default subclient, you can do so as described in the following sections.

  1. From the CommCell Browser, navigate to Client Computers > virtualization_client > Virtual Server > Hyper-V > backup_set.

  2. Right-click the default subclient and then select Properties.

  3. Click the Content tab. The Contents of subclient list displays All unprotected VMs as the content Type.

    That entry indicates that all virtual machines from the Hyper-V cluster, if they are not included in any other subclient in the given backup set, will be added automatically to the default subclient.

  4. Use the Add or Browse button to add one or more entries to back up specific VMs or sets of VMs. You can select specific virtual machines or add rules to identify virtual machines by categories such as virtual machine, host, or volume.

  5. To remove the default coverage for all virtual machines not covered by other subclients, select All unprotected VMs from the list and click Delete.

  6. Click OK.

If you remove all the entries from the Contents of subclient list, the All unprotected VMs will appear again in the list.

To enable backup jobs for non-default subclients to complete successfully when no virtual machines are discovered for non-default subclients, configure the AllowEmptySubclient additional setting on the Virtual Server Agent proxy.

Selecting Virtual Machines for Backup

You can browse and manually select virtual machines or any other Hyper-V objects for backup. You can easily navigate to the required object using the Browse option and select it as a content of a subclient. You can select objects, such as hosts, virtual machines, volumes, and cluster shared volumes. When you select a Hyper-V object, all its child objects are automatically selected for backup. For example: If you select a host, all the virtual machines on the host are automatically selected for backup.

Note

You can include Unicode characters for virtual machine path names.

The Browse dialog box provide following views for an Hyper-V cluster:

View

Description

Hosts View

This view will be useful when you want to select hosts and clusters for backup. This is the default view.

VMs View

This view will be useful in the following scenario:

  • You want to backup multiple virtual machines and they exist on different hosts.

  • You want to backup a specific virtual machine and you know the host where the virtual machine exist.

Storage View

This view will be useful when you want to backup all the virtual machines from a cluster shared volume or a local volume.
Hosts View

Follow the steps give below to browse the Hosts, Clusters and their child objects and then select the required objects.

  1. From the CommCell Browser, navigate to Client Computers > virtualization_client > Virtual Server > Hyper-V > defaultBackupSet.

  2. Right-click the subclient and select Properties.

  3. Click the Content tab.

  4. Click Browse. The Hosts view is displayed by default.

  5. Expand any object to view the child objects.

Wildcards

You can use wildcards to define patterns for content and filters for a subclient or backupset. You can use wildcards when defining a rule for a VM Name Pattern, Guest OS, Guest DNS Hostname, Host, or when defining disk filters.

The following table describes how to use wildcards when defining the subclient content or filters:

NOTES

If a subclient's content consists of wildcard characters and no eligible virtual machines are found for backup, the backup operation completes successfully even though no VMs are backed up.

Letters used in wildcard expressions are matched regardless of case; for example, 'a' matches both 'a' and 'A'.

Wildcards

Description

Examples

*

Any number of characters

This wildcard is used to match all objects where the object name contains a specific pattern.

For a VM name pattern, *test* matches any virtual machine whose name contains the string 'test' (at the beginning, end, or middle of the name).

?

Any one character

This wildcard is used to match any object for which a single character in the object name is variable.

DC? matches any object that starts with DC followed by a single additional character (such as DC1, DC2, DCa. or DCX).

[ ]

Set or range of characters

Not supported for host names.

[a-m]* matches any object whose name begins with the letters 'a' through 'm'.

[ ! ]

The negation of a set or range of characters

This wildcard matches objects for which the name does not include the specified set or range of characters.

Not supported for host names.

For example, [!AEIOU]* would match all object names that start with a letter other than A, E, I, O, or U.

[!A-C]* would match all names that do not start with the letters 'A' through 'C'.

Automatic Discovery of Virtual Machines for Backup

The Automatic Discovery feature enables you to discover virtual machines based on the specified criteria. This is feature is useful in environments where virtual machines are added, removed, or relocated on a frequent basis. You can set criteria to automatically include virtual machines into a subclient.

Notes

If an automatic discovery rule for a subclient identifies an entity that cannot be found, a backup job for the subclient fails. For example, if a rule points to a host that has been retired, that is treated as a failure during discovery, and the backup job fails.

To enable backup jobs to continue when an entity is not found, add the bAllowMissedContent additional setting on the Virtual Server Agent proxy and set the value to true.

To generate a warning message when a content entity or rule does not return any results, add the bWarnEmptyContentRule additional setting on the Virtual Server Agent proxy and set the value to true.

For steps to add an additional setting, see Adding or Modifying Additional Settings from the CommCell Console.

The following sections explain how to define rules for automatic selection of virtual machines:

Backup Set Filtering

Filters can be configured in backup set properties to exclude virtual machines or virtual machine disks from backups for all subclients under the backup set. The same types of filtering that are available for subclients are also available for backup sets.

For each subclient under a backup set, the filtering specified for the backup set is combined with the filtering for the subclient to determine which content is excluded from backups. Any filtering defined in a backup set is also visible in the subclients under the backup set.

If a virtual machine is explicitly added to the content of a subclient, the virtual machine will be discovered by its GUID. If the display name changes later, the machine is still included in the subclient as long as its GUID remains the same. Any virtual machines identified in a subclient and discovered by their GUIDs will not be filtered from backups.

For subclients that are upgraded from Commvault Version 9 and have virtual machines or disks marked using the Do Not Backup option, those items are automatically added to the filters for subclients and backup sets.

You can use wildcard characters when adding a pattern to define a rule for a VM Name Pattern, Guest OS, Guest DNS Hostname, Host, Datastore, or virtual machine disk. For more information, see the "Wildcards" section on this page.

You can create the following types of filters:

  • Virtual Machine Filters:

    • With a Specific Display Name

    • From a Specific Host

    • Based on a Name Pattern

    • With a Specific Operating System Group

    • From a Specific DNS Hostname

  • Disk Filters:

    • With a Specific Device Node

    • Based on a Disk Name Pattern

      • VM Name/Pattern - Enter a pattern (for example, Test* to exclude VMs for which the VM name begins with "Test").

      • Guest OS - Enter the exact name of the operating system or a pattern to identify an operating system group (for example, Microsoft* to filter any virtual machine that has a version of the Windows operating system).

        Note

        The virtual machine must be powered on at the time of the backup.

        Hyper-V integration services must be installed and updated on the virtual machine.

      • Guest DNS Hostname - Enter a pattern to identify a hostname or domain (for example, myhost.mycompany.com to exclude a specific host or *mycompany.com to exclude all hosts on that domain).

        Note

        The virtual machine must be powered on at the time of the backup.

        Hyper-V integration services must be installed and updated on the virtual machine.

    4. Click OK to add the filter.

  5. Add filters for virtual machine disks:

Displaying Backed Up Virtual Machines in the CommCell Console

Prerequisites

  • The virtual machine must be powered on at the time of the backup.

  • The Hyper-V integration services must be installed and updated on the virtual machine.

If these prerequisites are not satisfied, the virtual machine will appear as a client computer. However, the hostname and DNS will not appear in the Client Computer Properties dialog box.

Note

If you remotely install any software on a virtual machine and any required information such as the host name is missing from the database, the installation fails. If you interactively install any software on the virtual machine and any information such as the client name or host name is different, the virtual machine is treated as a new client and a duplicate client is created. To avoid duplicate client entries caused by different client or host names, use the install software option for the client level in the CommCell Console rather than interactively installing software to the virtual machine guest operating system.

Configuring Backups for Virtual Machines Hosted on SMB Shares

You can back up and restore virtual machines residing on Server Message Block (SMB) 3.0 shares.

Note

The VSA Proxy for Cluster Shared Volumes feature does not support backup of virtual machines hosted on SMB.

Prerequisites

The following requirements must be met before backing up any virtual machine from the SMB shares. If there are multiple nodes, fulfill these requirements for every node of the scale-out file cluster.

  • The Application server and file server must be running on Windows Server 2012 or later.

  • The File Server VSS Agent Service server role must be enabled on the file servers.

  • Application servers and file servers must be connected to an Active Directory domain residing in the same Active Directory forest.

  • The user account for the virtualization client must be part of the following administrator groups on the Hyper-V host:

    • Local Administrators group

    • Hyper-V Administrators group

    For a Hyper-V cluster, the user account must have full Cluster Permissions (Read and Full Control).

IntelliSnap requirements:

  • IntelliSnap backups of virtual machines on SMB shares are only supported for SMB 3.0 and the following storage arrays:

    • NetApp version 8.2 or later

    • Nutanix 4.6 or 4.7

  • For IntelliSnap, the MediaAgent must be running on Windows Server 2012 R2 or later.

  • The NetApp Vserver where the virtual machine resides must be added on the storage array. For more information on configuring NetApp Vserver, see Getting Started for NetApp.

    For instructions on configuring the virtual machines on NetApp Array, see Configuring Storage Virtual Machines on NetApp Arrays.

  • To reduce the number of snapshots of the SMB share during backup operations, configure the bForceSingleProxyBackup additional setting.

    To the VSA proxy that acts as the coordinator node for backups, add the bForceSingleProxyBackup additional setting as shown in the following table.

    For instructions about adding additional settings from the CommCell Console, see Adding or Modifying an Additional Setting.

Crash Consistent Backups for IntelliSnap

By default, IntelliSnap backups on Cluster Shared Volume storage are application-consistent. You can configure your subclient to run an application-consistent or a crash-consistent IntelliSnap backup.

For instructions, see Enabling Crash-Consistent Backups.

Notes:

  • For Hyper-V virtual machines residing on SMB shares, IntelliSnap backups are always crash-consistent, irrespective of the subclient configuration.

  • For a Cluster Shared Volume that resides on SMB shares, IntelliSnap backups are application-consistent.

Changed Block Tracking for IntelliSnap

Enable Changed Block Tracking (CBT) to optimize incremental backups of virtual machines by reading only the allocated and modified portions of virtual disks. Incremental backups can use Commvault CBT, native Microsoft CBT, or Cyclic Redundancy Check (CRC):

  • For Hyper-V virtual machines running on Windows Server 2012 R2 editions, Commvault CBT enhances backup performance of VHDX-format disks.

    The Commvault CBT mechanism is provided as a CVCBT driver along with the Virtual Server Agent (VSA) software. If CBT is enabled and if both the VSA proxy and the virtual machine proxy are running on a Windows Server 2012 R2 node, Commvault changed block tracking is used. The driver is supported on all editions of Windows Server 2012 R2 (Hyper-V Core, Standard and Datacenter editions). The VHDX files can reside on local volumes, cluster shared volumes, or SMB shares. CBT is not supported for backups on remote SMB (Server Message Block Protocol) shares.

    When you run IntelliSnap backups, the CBT driver monitors the virtual disks and maintains a bitmap (.cvf) file of the blocks that have changed. During subsequent backup copy operations, these bitmap files are read and only the changed data blocks are copied.

  • Backups of VHD-format disks and virtual machines running on Windows Server 2008 R2 or Windows Server 2012 continue to use the Cyclic Redundancy Check (CRC) mechanism to back up the parts of virtual disks that have changed since the last full backup. With CRC, the amount of data that is transferred to the MediaAgent is less, but the backup operation must read and compute the CRC checksum against all disk blocks. The time required for the disk I/O operations increases the total time of incremental backups to nearly as long as full backups.

Windows Server 2016

  • For Windows Server 2016 or later, Commvault CBT uses Microsoft's Resilient Change Tracking (RCT) feature to track changed blocks on the virtual disks.

  • Changed Block Tracking is supported only for backup copy jobs. Though the checkpoint is taken and the reference point is then saved during the IntelliSnap backup operation, changed block tracking is applied only when a backup copy job is run.

  • For virtual machines running in a Windows Server 2016 Hyper-V cluster, the use of checkpoints for backups simplifies the backup process. For each virtual machine, the backup takes a checkpoint that includes only that virtual machine. Once the backup is completed, the checkpoint is converted to a reference point with a unique ID and saved with the backup. Changed block tracking uses the reference point to identify changes since the last backup. The reference point is retained until the next backup is completed and a new checkpoint is generated.

  • In a mixed mode cluster where some nodes have not yet been upgraded from Windows Server 2012 R2 to Windows Server 2016, Windows Server 2016 operations are not supported until all nodes in the cluster are upgraded to 2016 and the functional level of the cluster is switched to Windows Server 2016 mode. Backups and restores use the same processes as Windows Server 2012 R2. With this, the behavior of changed block tracking varies:

    • If both the VSA proxy and the virtual machine proxy are running on a Windows Server 2012 R2 node, Commvault changed block tracking is used. Otherwise, incremental backups use the VSS backup method with CRC for changed block tracking.

    • If a virtual machine fails over from a Windows Server 2012 R2 node to a Windows Server 2016 node, incremental backups use the VSS backup method with CRC for changed block tracking. If the virtual machine fails back to a Windows Server 2012 R2 node, CBT resets and the next incremental backup includes all of the virtual machine data (equivalent to a full backup).

  • In a new Windows Server 2016 cluster, virtual machines are version 8 or later. In a cluster that has been upgraded to Windows Server 2016, virtual machines using older versions can still run, but cannot use all Windows Server 2016 host features. For example, all virtual machines running on a Windows Server 2016 node must be upgraded to version 8 or later before they can use Windows Server 2016 changed block tracking. In a Windows Server 2016 node that includes older version VMs, incremental backups include all of the virtual machine data (equivalent to a full backup).

Limitation

For Native Microsoft Changed Block Tracking to be validated successfully, you must specify a Windows 2016 host as the backup copy host. Older operating systems can be used to perform backup copy operations; however, traditional CRC backups will be performed during incremental backup jobs.

For more information about Changed Block Tracking for Hyper-V, see Changed Blocked Tracking.

For instructions on enabling or disabling CBT, see Enabling or Disabling Changed Block Tracking.

Configuring Backups Using Hardware VSS Provider from Storage Vendor

You can perform backups using the hardware VSS Provider offered by the storage vendor. Using a hardware VSS Provider can improve the performance of backup operations; for Hyper-V clusters, it reduces the amount of time that cluster shared volumes are caught in redirected-access mode.

Perform the following steps to configure the VSSProvider additional setting to use the vendor's hardware VSS provider:

  1. From the CommCell Browser, go to Client Computers.

  2. Right-click a client computer, and then click Properties.

  3. On the General tab of the Client Computer Properties dialog box, click Advanced.

  4. Click the Additional Settings tab.

  5. Click Add.

  6. On the Add Additional Settings dialog box, provide the following information:

    • Name: Type VSSProvider.

    • Category: Select VirtualServer (the default value).

    • Type: Select STRING (the default value).

    • Value: Enter the hardware VSS Provider ID of the vendor.

      To find the ID, run the following command on your client computer:

      vssadmin list providers

      An example of a provider ID (for NetApp) is ddd3d232-a96f-4ac5-8f7b-250fd91fd102.

    • Ensure that the Enable option is selected.

    • Click OK to add the additional setting.

  7. Click OK twice to save the client properties.

Your backup operations will use the hardware VSS Provider instead of the software VSS Provider from Microsoft.

Configuring Pre-processing and Post-processing for Backups

Setting Up Pre-processes and Post-processes

You can add and modify Pre-processes and Post-processes for a subclient. These are batch files or shell scripts that you can run before or after certain job phases. For example, you can use an echo command to check the level of a backup. Similarly, you can include a case statement within a script to run specific operations based on the level of the backup job.

A Save As Script file can also be run as a pre-process and post-process, if you include the absolute path of the associated input file in the script file.

See Pre-processes and Post-processes - Commands and Arguments for information on additional arguments that the CommServe sends to the Pre-processes and Post-processes.

The first line of the script must execute a command that is designed to call in the pre/post program. Ensure that you have included the appropriate command in the first line of the script.

The following is an example of a typical pre/post script:

#!/bin/bash base='basename $0' echo $0, 'date' > /extra/aah/RESULTS/$base.out exit 0

  1. From the CommCell Browser, navigate to Client Computers | <Client> | File System | Backup Set.

  2. Right-click the <Subclient> in the right pane, and then click Properties.

Deleting an Instance, Backup Set, or Subclient

The following sections describe the steps involved in deleting an instance, backup set, or subclient.

When you delete an instance or backupset, the associated data is logically deleted and you can no longer access the corresponding data from CommCell Console for recovery purposes.

Refer to Recovering data associated with deleted clients and storage policies for information on how to recover data if you accidentally delete an entity.

Deleting an Instance

Consider the following before deleting an instance:

  • When you delete a specific instance all job schedules and job histories that pertain to any of the levels within the deleted instance are deleted.

  • You cannot delete an instance if it is being backed up. Attempts to delete an instance under such conditions cause the deletion to fail. If a backup is in progress, either wait for the backup to complete or kill the backup job using the Job Controller. Once the backup is no longer in progress, you can delete the instance level.

  • You cannot delete an instance if there is only one instance present for an agent. To delete the final instance, you must remove the agent software from the client computer.

Procedure

  1. From the CommCell Browser, right-click the instance that you want to delete, click All Tasks and then click Delete.

  2. Click Yes to confirm the deletion. (Clicking No cancels the deletion and retains the node.)

  3. Type the requested phrase in the Enter Confirmation Text dialog box and click OK. This should delete the instance.

Deleting a Backup Set

Consider the following before deleting a backup set:

  • You cannot delete a default backup set.

  • Schedules associated with the backup set are also automatically deleted.

  • From the CommCell Browser, right-click the user-defined backup set that you want to delete, and then click Delete from the shortcut menu.

    A confirmation message is displayed, asking if you want to delete the backup set.

  • Click No to cancel the deletion and retain the backup set, or click Yes to continue the deletion.

You can perform the steps provided in Creating an Alert from the Alert Wizard to configure a data protection alert for virtual machines. You can configure alerts to provide notification and details about specific virtual machines when jobs are started, suspended, resumed, killed, completed, or failed. The alert notification can include tokens for the virtual machine name, host, status, and protection failure reason.

The following alerts are available for the Virtual Server Agent:

    • <VM STATUS>

    • <VM FAILURE REASON>

  • On the User(s) and User Group(s) Selection page, add users to receive notifications for the alert.

The notifications generated for the alert include information about all discovered virtual machines for the selected virtualization clients.

Notes

  • For any subclients that have backups disabled (on the Activity Control tab of the subclient properties), discovered VMs are not included in alerts.

You can choose to receive notifications in different ways. For more information, see Alert Notification Type Overview.
