Managing Client Computer Groups

Once a client computer group is created, you can configure or modify the following options:

Associating or Disassociating Clients

You can associate clients to or disassociate clients from a client computer group. (If the client group has Automatic Associations selected, see Overview of Smart Client Computer Groups Using Automatic Association.)

Note: If you associate a client group to a disk or a cloud Network Storage Pool, and if you add a new MediaAgent to the client group, then it is automatically shared across all the mount paths available in the library.

  1. From the CommCell Browser, go to Client Computer Groups.
  2. Right-click the client_computer_group and then click Properties.

    The Client Group dialog box appears.

  3. On the General tab, press the Ctrl key and select the clients that you want to move, and do one of the following:
    • To associate clients to a client group, click the Include > button to move the selected clients to the Clients in this group list.
    • To disassociate clients from a client group, click the < Exclude button to move the selected clients to the All clients list.
  4. Click OK.

Associating or Disassociating Users, User Groups, and Roles

You can associate users, user groups, and roles to or disassociate users, user groups, and roles from a client computer group.

  1. From the CommCell Browser, go to Client Computer Groups.
  2. Right-click the client_computer_group and then click Properties.

    The Client Group dialog box appears.

  3. Click the Security tab.
  4. To associate users, user groups, and roles to a client group, click Add.
  5. To disassociate users, user groups, and roles from a client group, select the row containing the user/user group and role and click Remove.
  6. Click OK.

Enabling or Disabling Activity Control

Activity Control allows you to enable or disable all of the backup, restore, and data aging operations on all client computers that are members of a client computer group.

  1. From the CommCell Browser, go to Client Computer Groups.
  2. Right-click the client_computer_group and then click Properties.

    The Client Group dialog box appears.

  3. Click the Activity Control tab.

    By default, the Enable Backup, Enable Restore, and Enable Data Aging check boxes are selected.

  4. Optional: To disable an activity, clear the appropriate check boxes.
  5. Click OK.

    If the backup or restore activities are disabled, the client computer group icon is marked with a red X in the CommCell Browser.

Change the Client Computer Group Name

Use the following steps to change the name of a client computer group.

  1. From the CommCell Browser, go to Client Computer Groups.
  2. Right-click the client_computer_group and then click Properties.

    The Client Group dialog box appears.

  3. Click the General tab.
  4. In the Group Name box, type the new name of the client computer group.
  5. Click OK.

Configuring Firewall Settings

You can define the connection details for incoming and outgoing connections required to operate the client group across the firewall by configure firewall settings.

Use the following steps to configure firewall settings for a client computer group:

  1. From the CommCell Browser, go to Client Computer Groups.
  2. Right-click the client_computer_group and then click Properties.

    The Client Group dialog box appears.

  3. Click Network.
  4. In the Network Properties for Client Group: client_group_name dialog box, click the Firewall Configuration tab.
  5. Select the Configure Firewall Settings check box and select the firewall options applicable to your firewall settings.

    See Firewall for more information.

  6. Click OK.
  7. Right-click the client_computer_group and then click All Tasks > Push Firewall Configuration.

    The configuration is applied to all clients. You can verify the new firewall configuration on each client computer.

Use the following steps to configure a client to inherit the firewall settings from the client computer group.

  1. From the CommCell Browser, go to Client Computers.
  2. Right-click the client and then click Properties.

    The Client Computer Properties dialog box appears.

  3. Click Network.
  4. In the Network Properties for Client: client_name dialog box, click the Firewall Configuration tab.
  5. Clear the Configure Firewall Settings check box.
  6. Click OK.

    Future firewall changes will be applicable at the client group level.

When Configure Firewall Settings is selected, the firewall configuration of both the client computer and client group are merged in the client computer.

Configuring Network Throttling

The network traffic for clients and MediaAgents can be throttled based on the network bandwidth in your environment. This is useful if you want to limit the network bandwidth usage.

By default, network throttling is disabled. You can enable the throttling options for multiple clients by configuring this option on the client computer group. Once configured, the throttling options are applied to all data transfer and control message operations, for example, Data Protection operations including Laptop Backups, Dash copy, and Data Recovery Operations.

  1. From the CommCell Browser, go to Client Computer Groups.
  2. Right-click the client_computer_group and then click Properties.

    The Client Group dialog box appears.

  3. Click Network > Network Throttle tab.
  4. Select the Enable Network Throttling check box.
  5. Under the Client Computer Groups node, select the client computer groups to setup throttling.
  6. By default, the All clients share allocated bandwidth check box is selected to share the throttling settings among all selected clients cumulatively.

    If this check box is cleared, each client will throttle at the configured rate instead of a combined and shared rate.

  7. In the Throttling Schedule area, click Add to setup throttling rules.

    Example

    • Days of Week - select a day or multiple days for the schedule to run.
    • Time Interval - select Whole day or a specific time interval for the schedule to run.

    You can select one of the following to specify a throttling rate:

    • Use Absolute Throttling

      Click the Throttle Send and Throttle Receive check boxes and enter the values for each.

    • Throttle Relative to Bandwidth

      This feature lets you enter a threshold, and throttling percentage. While sending or receiving, the client monitors the rate at which it can send or receive data. As long as the threshold you enter is below the actual rate, the client sends or receives as fast as the network will allow. If the actual transmission rate falls below the threshold you set, however, the client backs off, sending or receiving data at only the throttling percentage you have set. For example, if your threshold is 500Kb/sec, and your percentage is 40%, transmission is throttled back to 200Kb/sec.

      The client imposes this constraint for a fixed period, then attempts to operate at full speed again. If it finds that conditions have improved (that is, that it can now send or receive data at a rate greater than the threshold you set), it stops throttling. If it still cannot send send or receive above the threshold rate, it continues to operate at the throttled percentage for another period, and so on, until the job completes.

      • Select If send bandwidth is less than (Kbps) to enter a sending rate threshold, and a percentage rate to throttle the sending rate to if that threshold is crossed.
      • Select If receive bandwidth is less than (Kbps) to enter a receiving rate threshold, and a percentage rate to throttle the receiving rate to if that threshold is crossed.
  8. Click OK to save the throttling rule.

    The new throttling rule appears in the Throttling Schedule area.

  9. Click OK.

Cloning a Client Computer Group

Use the following steps to clone a client computer group.

  1. From the CommCell Browser, go to Client Computer Groups.
  2. Right-click the client_computer_group and then click Clone.
  3. In the Group Name box, type a name for the clone.
  4. Update the properties of the clone.

    For information on client computer group properties, see Managing Client Computer Groups.

  5. Click OK.

Deleting a Client Computer Group

Use the following steps to delete a client computer group.

  1. From the CommCell Browser, go to Client Computer Groups.
  2. Right-click the client_computer_group and then click All Tasks > Delete.
  3. Click Yes to confirm the deletion.

    The client computer group is deleted, but the clients that were in the client computer group are still available.

Configuring User Accounts for SQL Server Agent Backups

This user account will be used for all computers within a Client Computer Group. Configure the user account at this level if different users will be conducting backup and restore operations for each Client Computer Group in your organization. This user account will override the user account configured at the CommCell level.

  1. From the CommCell Browser, navigate to the Client Computer Groups node.
  2. Verify that all the Agent clients for which you wish to configure the user account are included in the Client Computer Groups.
  3. Right-click the <Client Group> and click Properties.
  4. Click the Advanced Settings tab.
  5. Click the Override higher levels settings check box.
  6. Select one of the following:
    • Use Local System Account, if the computer's Administrator account contains the required privileges.
    • Impersonate User, if you want to use a different account that contains the required privileges. Type the User Name and Password for this account in the space provided.
  7. Click OK.

We recommend that you associate a SQL client to only one client group that has a user account configured at the client computer group level. Else, you can also set the user account at the client level or the instance level.

Configuring Operation Window

By default, all operations in the CommCell will run for 24 hours without restriction. However, it may be necessary to prevent operations from running during certain time periods of the day, e.g., during the day time when the resources are busy. To accomplish this, you can define operation rules which will enable certain operations to be run during idle periods, thereby not consuming resources such as network bandwidth, data, or storage resources during busy hours. For more information, see Operation Window.

Use the following steps to configure operation rules.

  1. From the CommCell Browser, navigate to Client Computer Groups.
  2. Right-click the client_computer_group and then click All Tasks > Operation Window.
  3. From the Operation Windows dialog box, click Add.
  4. In the Operation Rule Details dialog box, specify the following:
    1. In the Name box, type a name.
    2. From the Operation, select either an administration, data protection (either full or non-full), and/or a data recovery operations.
    3. From the Days of week, select the days of the week to exclude the operation.
    4. From the Do not run intervals pane, click Add to add a date interval that will prevent the selected operations from running.

      From the Time Intervals dialog box, select a start and end time to exclude the operations from running, then click Add. Click OK to close the Time Intervals.

  5. Click OK twice.

Viewing the Job History
