Use this tab to establish the storage device related settings on the selected subclient.
The following tabs are displayed:
Use this tab to select or view storage policy settings on the selected subclient.
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, click 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.
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.
Number of Data Backup Streams
Displays the number of streams used for backup operations. To change the number of streams, select or type the desired number in the list. For DB2 MultiNode, be sure to set the appropriate number of streams for each database partition by double-clicking the appropriate Stream space and typing the desired number.
Use this tab to establish the options for data transfer.
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.
Click to disable software compression.
Note that hardware compression has priority over the software compression. Hardware compression is established in the Data Path Properties dialog box. The above software compression option will take 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.
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.
Indicates the processes used by the client to transfer data based and whether bandwidth throttling is enabled or not.
- Network Agents
Specifies the number of data pipes/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. On non-UNIX computers, the default value is 2 and a maximum of 4 can be established if necessary. On UNIX computers the default value is 1 and a maximum of 2 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 therefore 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 will be 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.
Note that throttling is done on a per Network Agent basis.
Use this tab to establish the options for deduplication on the subclient.
Specifies whether deduplication for the subclient is enabled or disabled, and if enabled whether the signature generation (a component of deduplication) is performed on the client or MediaAgent computer.
Note that deduplication is supported on disk storage devices. So the deduplication options are applicable only if the subclient is associated with a Storage Policy containing disk storage.
Click to enable signature generation on the client computer.
Click to enable signature generation on the MediaAgent computer.
