Updating an Azure VM Group

When you update an Azure VM group, you can update many settings, including the server plan, the VMs that are associated with the VM group, roles and permissions, and access nodes.

Go to the VM Group

1. From the Command Center navigation pane, go to Protect > Virtualization.

   The Virtual machines page appears.

2. On the VM groups tab, click the VM group.

   The VM group page appears.

Select a Different Plan or Policy

This section is named either "Plan" or "Policy", depending on whether the VM group is associated with a plan that was created in the Command Center or a storage policy that was created in the CommCell Console. You cannot change that selection for an existing VM group, but you can select a different plan or policy, as follows:

• When modifying the Plan setting, you can select a plan that was created in the Command Center.

• When modifying the Policies setting, you can make the following changes:

  • From the Storage policy list, you can select a storage policy that was created in the CommCell Console or a plan that was created in the Command Center.

  • You can select a schedule policy that was created in the CommCell Console.

• On the Overview tab, in the Summary section, for Plan, click the edit button .

• From the Plan list or the Policies list, select the plan or the policy.

• Click Submit.

Specify the Time Zone

To schedule operations for the VM group based on a specific time zone, specify that time zone for the VM group.

1. On the Overview tab, in the Summary section, for Time zone, click the edit button .

2. From the list, select the time zone.

3. Click Submit.

View Recovery Points

The Recovery points section shows the backups that are available by date. For information about restores, see Restoring Azure VMs and Files.

View Policies

If the VM group is not associated with a plan, the Policies section shows the storage policy and the schedule policy that the VM group is associated with.

View Schedules

If the VM group is not associated with a plan, the Schedules section shows the backups that are scheduled for the VM group.

Assign Roles to Users or User Groups

To allow a user or user group to perform data management operations on the VM group, create a security association between the user or user group and one of the following pre-defined roles:

• View: Provide read-only access to application group configuration, job history, and reporting data

• VM End User: Provide self-service backup, recover both in-place and out-of-place

Procedure

1. On the Configuration tab, in the Security section, click the edit button .

   The Security dialog box appears.

2. Enter the name of the user or user group, select the role to assign, and then click Add.

3. Click Save.

Use Cyclic Redundancy Checking Instead of Changed Block Tracking

With changed block tracking (CBT), backups write only blocks that changed after the previous backup. You can use CBT with unmanaged and managed disks. For virtual machines that have a known issue with CBT, you can turn off CBT to run backups using the cyclic redundancy check (CRC) method instead.

• On Configuration tab, in the Options section, move the Use changed block tracking toggle key to the left.

Enable Automatic Detection of VM Owners

Virtual machine owners can be assigned automatically during virtual machine discovery, based on privileges and roles defined in the Azure portal. For more information, see VM Owner Detection for Azure.

• On Configuration tab, in the Options section, move the Auto detect VM owner toggle key to the right.

Modify the Number of Readers for Parallel Operations

If you have the Agent Management permission, you can modify the number of parallel read operations that can be launched during backups. (If you don't have the permission, the No. of readers setting is hidden.)

The default number of readers, 5, is tuned and validated by Commvault to function optimally with access nodes that meet the requirements for Azure VM access nodes.

If additional CPU and RAM are provisioned to your Azure VM access nodes, you can increase the number of readers that your access nodes use.

1. On Configuration tab, in the Options section, click the edit button .

   The Edit options dialog box appears.

2. In the No. of readers box, enter the number of readers to use.

3. Click Save.

Modify the Backup Type

If you change the VM backup type between File System and Application Consistent and Crash Consistent, Commvault forces a full backup.

1. On Configuration tab, in the Options section, click the edit button .

   The Edit options dialog box appears.

2. For Virtual machine backup type, select one of the following options:

   By default, when a VM group is created, the backup type is crash consistent.

   • Application aware: Uses in-guest application plug-ins to assist in quiescing the file system and applications and in supporting granular application data recovery.

   • File system and application consistent: Uses VM restore points to perform a point-in-time application-consistent snapshot of all the managed disks of the VM.

     For the File System and application consistent backup type, consider the following:

     • When a Windows VM is running and the VM agent is in a ready state, Azure creates an application-consistent restore point.

     • When a Linux VM is running, Azure creates a file-system-consistent restore point.

     • When a Linux or Windows guest VM is not running, Azure creates a crash-consistent restore point.

   • Crash consistent: Uses an Azure software snapshot for a basic backup of the VM.

   • Application-based backups: Performs application discovery for those VMs selected within the VM group and configures backups by installing an in-guest application agent. For more information, see Application-Based Backups.

3. Click Save.

Enable IntelliSnap

Procedure

• On Configuration tab, in the Options section, move the IntelliSnap toggle key to the right.

Results

When you enable IntelliSnap on a VM group, Commvault automatically does the following:

• Creates schedule policies for the primary (snap) and backup copies.

• Enables IntelliSnap for the plan that is associated with the VM group.

• Sets the plan to retain 8 snap recovery points. (You can modify the server plan to specify a different number of snaps to retain.)

Enable File Indexing

Procedure

• On Configuration tab, in the Options section, move the Index files after backup toggle key to the right.

Specify the Time That Backup Jobs Start

You can specify the time of day that you want scheduled jobs for the VM group to start. By default, Commvault starts jobs based on the RPO (recovery point objective) settings of the plan that is specified for the application group.

If you modify the Backup job start time value, but the time that you enter is not within the time period that is set in the backup window or the full backup window for the server plan, then Commvault starts jobs at the next available time within the window.

Set the Backup job start time in the local time zone of the hypervisor. Commvault uses the Time zone setting of the VM group to ensure that jobs are started at the Backup job start time, in the local timezone of the hypervisor.

1. On Configuration tab, in the Options section, for Backup job start time click the edit button .

2. Enter the time for jobs to start.

3. Click Submit.

Disable Backups

When you disable backups, the VM group is excluded from SLA calculations.

• On Configuration tab, in the Activity control section, move the Data backup toggle key to the left.

Exclude the VM Group from SLA Calculations

You can exclude the VM group from SLA calculations.

1. On Configuration tab, in the Options section, click the edit button .

   The SLA exclusions dialog box appears.

2. Move the Exclude from SLA toggle key to the right.

3. To exclude the VM group only for a period of time, click Include after a delay, and then select the amount of time.

4. Select one of the following options:

   • Exclude permanently

   • Service provider action pending

   • Customer action pending

5. If necessary, in Reason for exclusion, enter an explanation for excluding the VM group.

Modify Tags

If you have the Tag Management permission, you can create and apply tags to the hypervisor. For more information, see Entity Tags.

1. On Configuration tab, in the Tags section, click the edit button .

   The Manage tags dialog box appears.

2. In Tag name, enter a name for the tag.

3. To assign a value, in Tag value, enter the value.

4. Click Save.

Modify the Access Nodes

By default, VM groups inherit access nodes from the hypervisor. If you want to control the access node resources that are used for the VM group (for example, dedicated resources for mission-critical applications), you can specify different access nodes.

To ensure that multiple access nodes are available to perform backups and other operations, regardless of planned or unplanned outages for individual access nodes, use access node groups (also called server groups).

Select Different Access Nodes

1. On Configuration tab, in the Access node section, click Actions, and then select Edit.

   The Edit access node dialog box appears.

2. Select the access node group or the access nodes to use for the VM group.

3. Click OK.
