Setting Up Network Bandwidth Throttling for Subclients

Network bandwidth throttling for a subclient is set on a per-network agent basis.

Setting Network Bandwidth and Network Agents for a Backup Operation

For most agents, the network bandwidth option is available at the subclient level. For some database agents, this option is also available at the instance level.

Note: All subclients support network bandwidth throttling, except subclients that use NAS agents.

To set a limit for network bandwidth and the number of concurrent network agents for a subclient backup operation, perform the following steps:

  1. In the CommCell Browser, expand Client Computers > client_name > agent > backup set or instance.

    Note: If limits are set at the instance level and the subclient level, the subclient settings override the instance settings.

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

    The Subclient Properties dialog box appears.

  3. For file system subclients, update the following:
    1. In the Subclient Properties dialog box, click Advanced.

      The Advanced Subclient Properties dialog box appears.

    2. On the Performance tab, in the Network Agents box, set the maximum number of network agents to run concurrently when performing a subclient backup.
    3. Select the Throttle Network Bandwidth (MB/HR) check box and then enter the throughput limit. The Commvault software throttles the transfer on a per-job basis.
    4. Click OK.
  4. For non-file system subclients, on the Storage Device tab, click the Data Transfer Option tab and then update the following:
    1. In the Network Agents box, set the maximum number of network agents to run concurrently when performing a subclient backup.
    2. Select the Throttle Network Bandwidth (MB/HR) check box and then enter the throughput limit. The Commvault software throttles the transfer on a per-job basis.
  5. Click OK.

Setting Network Bandwidth and Network Agents for Multiple Subclients Using Subclient Policy

For iDataAgents that support subclient policy, bandwidth throttling can be set while creating multiple subclients, by using a subclient policy.

Use the following steps to set the network bandwidth and network agents while creating multiple subclients:

  1. From the CommCell Browser, expand Policies.
  2. Right-click Subclient Policies, and then click New Subclient Policy.
  3. In the Name box, enter a name for the subclient policy.
  4. Click the iDataAgent list and then select Windows File System.
  5. Click once in the Storage Policy column cell and then select a storage policy for the default subclient.
  6. Click the Association tab, and then select the backup set on the client that you want to associate with this subclient policy.
  7. Click the General tab, select the default subclient row, and then click Edit.

    The Create New Subclient dialog box appears.

  8. On the Content tab, enter the contents for the subclient by browsing to them or by entering their path. If browsing, select a file or folder as content and then click Add.
  9. Click Close when you are done adding content.
  10. On the Performance tab, perform the following steps:
    1. In the Network Agents box, enter the number of network agents that must be used to perform backup operations on the subclient.
    2. Select the Throttle Network Bandwidth (MB/HR) check box and enter the throughput limit. The Commvault software throttles the transfer on a per-network-agent basis.
  11. Click OK.

The default subclient is automatically created in all the clients with which the subclient policy is associated.
