Storage Device

Use this dialog to establish the storage device related settings on the selected subclient.

The following tabs are displayed:

  • Data Storage Policy

  • Data Transfer Option

  • Deduplication

Data Storage Policy Tab

Use this tab to select or view storage policy settings on the selected subclient.

Storage Policy

Displays the storage policy to which this subclient is currently associated. To associate a storage policy to a new subclient or to change the storage policy associated with an existing subclient, select one in the list.

Incremental Storage Policy

Displays the name of the Incremental Storage Policy associated with this subclient, if the storage policy has the Incremental Storage Policy option enabled.

Data Paths

Click to view or modify the data paths associated with the primary storage policy copy of the selected storage policy.

Create Storage Policy

Click to launch the Create a Storage Policy wizard. Once the storage policy has been created, it will be displayed in the list of storage policies to which the selected subclient can be associated.

Data Transfer Option Tab

Use this tab to establish the options for data transfer.

Software Compression

Indicates whether software compression for the subclient or instance is enabled or disabled, and if enabled, whether it is performed on the client or MediaAgent computer.

  • On Client

    Click to enable software compression on the client computer.

  • On MediaAgent

    Click to enable software compression on the MediaAgent computer.

  • Use Storage Policy Settings

    Enable software compression to be controlled by the storage policy instead of subclient properties.

  • Off

    Click to disable software compression.

Hardware compression has priority over software compression. Hardware compression is established in the Data Path Properties dialog. The above software compression option takes effect when the data path is associated with a disk library, or when hardware compression is disabled in the data path associated with tape libraries.

Note

If the subclient is associated with a storage policy copy that is deduplicated, then the compression settings on the storage policy copy takes precedence. See Copy Properties (Deduplication) - Advanced tab for compression settings on deduplicated storage policy copy.

Resource Tuning

Indicates the processes used by the client to transfer data, based on whether bandwidth throttling is enabled.

  • Network Agents

    Specifies the number of data pipes and processes that the client uses to transfer data over a network. Increasing this value may provide better throughput if the network and the network configuration in your environment can support it. The default value is 2, and a maximum of 4 can be established if necessary.

  • Throttle Network Bandwidth (MB/HR)

    Specifies whether the backup throughput is controlled or not. (By default this option is not selected and the throughput is not controlled.) When selected, use the space to specify a value for the throughput. By default, this is set to 500. The minimum value is 1 and there is no limit to the maximum value. (In this case the backup throughput is restricted to the maximum bandwidth on the network.)

Use this option to set the backup throughput, based on the network bandwidth in your environment. Use this option to reduce the backup throughput, so that the entire network bandwidth is not consumed, especially in slow links. Increasing this value will end up consuming the bandwidth with the maximum throughput limited to the network bandwidth capability.

Throttling is done on a per Network Agent basis.

Deduplication Tab

Use this tab to establish the options for deduplication on the subclient.

Enable Deduplication

Use this option to enable or disable deduplication for the subclient.

When enabled, you can choose to generate the signature (a component of deduplication) on the client or on the MediaAgent computer.

Note

  • The deduplication is supported on disk storage devices. Therefore, the deduplication options are applicable only if the subclient is associated with a storage policy containing disk storage.

  • For source-side deduplication, the signature generation always occurs on the client.

On Client

Click to enable signature generation on the client computer.

On MediaAgent

Click to enable signature generation on the MediaAgent computer.
