Instance Properties (Storage Device)

Use the Instance Properties (Storage Device) tab to view or change the storage policy used to back up data via the command line for the selected instance, select a storage policy for backing up logs on the selected instance, or view or select a default storage policy for the selected instance.

• For DB2 DPF, use the Create DPF Client (Storage Device) tab to view or change the storage policy.

• For Oracle RAC, use the Create RAC Client (Storage Device) tab to view or change the storage policy.

Data Backup

• Default Storage Policy

  Specifies the default storage policy for the selected instance. You can use this space to select another storage policy. Click Data Paths to administer data paths for the storage policy. A changed storage policy will apply only to new subclients (i.e., those subclients that you subsequently create).

Command Line Backup

• Storage Policy used for user command backup of data

  Specifies the storage policy used for command line backups and restores. You can use this space to select another storage policy. A changed storage policy will apply only to new command line backup jobs (i.e., those command line backup jobs that you subsequently start).

• Command Line Storage Policy

  Specifies the storage policy used for command line backups and restores. You can use this space to select another storage policy. A changed storage policy will apply only to new command line backup jobs (i.e., those command line backup jobs that you subsequently start).

• Storage Policy used for sap user command

  Specifies the storage policy used by the SAP third-party command line command to back up data. You can use this space to select another storage policy.

• Default Storage Policy

  Specifies the default storage policy for the selected instance. You can use this space to select another storage policy. A changed storage policy will apply only to new subclients (i.e., those subclients that you subsequently create).

• Show Data Paths

  Click to display the details of the data paths associated with the primary storage policy copy of the selected storage policy.

Log Backup

• Storage Policy used for all Logical Logs / Archive Log backups

  Specifies the storage policy used by the subclients in this instance to back up logical log files. You can use this space to select another storage policy.

• Storage Policy for All Log Files

  Specifies the storage policy used by all backup sets in this instance for backing up log files. You can use this space to select another storage policy. A changed storage policy will apply only to new backup sets (i.e., those backup sets that you subsequently create).

  Notes

  • If you run a log backup operation from the CommCell Console, then data storage policy associated with the default subclient is used.

  • If you run a command line log backup operation from a third party application, then log storage policy associated with the instance is used.

• Number of Archive Log Backup Streams

  Click to specify the number of backup streams to be used for backing up Archive Log files. The maximum number of streams is determined by the value established for the Storage Policy. You can use this space to change the number of Archive Log Backup Streams.

Data Transfer Option

• Software Compression

  Select the software compression to be used for "Command Line Backup" in case hardware compression is not available or not selected on the destination storage policy copy.

• On Client

  Use the client's software compression functionality.

• On MediaAgent

  Use the MediaAgent's software compression functionality.

• Use Storage Policy Settings

  Click to use the settings enabled on deduplicated storage policy copy.

  This option applies when the 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

  Do not use software compression.

  The 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.

  Note

  For non-deduplicated storage policy copy, select On Client or On MediaAgent options to turn on compression, depending upon your environment.

• Resource Tuning

  Specify the number of processes (1-4) that the client uses to transfer data. Improvement in performance is resource dependent.

• Throttle Network Bandwidth (MB/HR)

  Specify the number of processors from available options.
