Use this dialog box to manage the File System Subclient properties.
Client Name
Displays the name of the Client computer to which this subclient belongs.
Billing Department
Displays the name of the billing department, when the subclient is associated with a billing department.
iDataAgent
Displays the name of the DataAgent to which this subclient belongs.
Backup Set
Displays the name of the Backup Set to which this subclient belongs
Subclient Name
Displays the name of this Subclient. You can use this space to enter or modify the name of the subclient.
Subclient Policy
Select a subclient policy from the list to associate with this backup set.
Use VSS
Select the Use VSS check box to use the Volume Shadow Service (VSS) for backups. Select one of the following options to specify which files you want to backup using VSS.
-
For all files
Select this option to use a software snapshot to perform the backup.
A software snapshot creation may fail if the VSS service is unavailable or it is unable to quiesce a volume. Select one of the following options to control the actions in such scenario:
-
Fail the job
If you select this option the backup job will fail and not continue in the case where the software is unable to create the snapshot. Use this option, if you want to perform the backup using only the software snapshot.
-
Continue and reset access time
If you select this option, the File System iDataAgent will perform the backup from the live volume . After backing up the file, the access time will be reset back to its original time before the backup occurred. Use this option, if you are archiving files based on access time. Note that resetting the access time may slow down the backup operation.
-
Continue and do not reset access time
This is the default option. The File System iDataAgent will perform the backup from the live volume. After backing up the file, the access time will NOT be reset back to its original time. Use this option, if you are NOT archiving files based on access time.
-
-
For locked files only
Select this option to use a software snapshot to perform the backup of locked files. Some applications and system programs lock certain files while in use (open). If you do not select this option, files that are locked are skipped during the backup job.
Note: To back up individual Distributed File System Replication (DFSR) nodes, select this option as the files may be locked during the replication process. However, the DFS-R configuration is backed up during a system state backup.
-
Backup from Live Volume
This is the default option. By default, the Windows File System iDataAgent will perform the backup from the live volume and not from the Snapshot of the volume.
Data Transfer Option
Use this tab to establish the options for data transfer.
Software Compression
Indicates whether software compression for the subclient 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
Click to use the settings enabled on deduplicated storage policy copy.
This option applies when subclient is associated with a storage policy copy that is deduplicated. See Copy Properties (Deduplication) - Advanced tab for compression settings on deduplicated storage policy copy.
-
Off
Click to disable software compression.
Note that hardware compression has priority over the software compression. 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.Resource Tuning
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. 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 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.
Deduplication
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.
Storage Policy
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, click one in the list.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.
