  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 group. Once configured, the throttling options are applied to all data transfer and control message operations, such as Data Protection operations including Laptop Backups, Dash copy, Data Recovery Operations, etc.

  1. From the CommCell Browser, navigate to Client Computers.
  2. Right-click the <Client Computer Group> and then click Properties.
  3. Click the Network Throttling tab.
  4. Click the Enable Network Throttling check box.
  5. Under the Client Computer Groups node, select the client computer groups to setup throttling.
  6. By default, 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. Click Add to setup throttling rules. For 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.

    The new throttling rule appears in the Throttling Schedule area.

  9. Click OK.

Deleting a Client Computer Group

Use the following steps to delete the client computer group.

  1. From the CommCell Browser, navigate to Client Computer Groups.
  2. Right-click the <Client Computer Group> that you want to delete and then click All Tasks | Delete.
  3. Click Yes to confirm the deletion.

    The client computer group is deleted, but the clients of the group are still available.

Configuring User Accounts for SQL Server iDataAgent 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.

Scheduling Automatic Updates

Use the following steps to schedule automatic updates to the members of a client computer group.

  1. From the CommCell Browser, navigate to Client Computer Groups.
  2. Right-click the <Client Computer Group> where you want to schedule the updates job and then click All Tasks | Add/Remove Software | Install Updates.
  3. Click the Reboot Client check box to have the system automatically reboot the client and/or MediaAgent computers if a reboot is required.
  4. Click the Job Initiation tab.
  5. Click Schedule to schedule the updates for a specific time.
  6. Click Configure button to set the schedule for the updates job.
  7. From the Schedule Details dialog box, select the appropriate scheduling options. For example:

    Type a name for the schedule in the Schedule Name box.

    1. Click Weekly.
    2. Check the days you want to run the updates job.
    3. Change the Start Time to 9:00 PM.
    4. Click OK to close the Schedule Details dialog box.
    5. Click OK to close the Backup Options dialog box.

    The Updates job will be executed as per scheduled.

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 day(s) 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 operation(s) from running.

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

  5. Click OK twice.
