• Create new store every - Days

  Option to create a new deduplication store based on interval of days.

• Create new store every - TB

  Option to create a new deduplication store based on store volume, in TB.

Total Number of Stores

Displays the total number of deduplication stores created.

Total size of Application Data across all the stores

Silo Options

Use this dialog box to configure the silo storage options.

Enable Backup of Deduplicated Data

Select this option to backup the deduplicated data from magnetic to tape media.

Keep Most Recent (Active) Silo in cache

Option to maintain the most recently accessed active silo data in the system cache.

Enable Space Management

Option to enable Silo space management on the magnetic media.

Enable Multiplexing

Option to enable multiplexing for silo operations. If selected, multiple data streams of data protection operations to the same media, can be run concurrently. Multiplexing is supported for Silo data protection operations.

Advanced

• Redundancy Factor

  Specifies the number of copies of the deduplicated objects/blocks to be maintained in the Deduplication Store. The default value is set to 1.

• Minimum Free Space (MB)

  Specifies the total amount of free space that must be available at all times in the volume in which the Deduplication Store is configured. If necessary, use the space to modify the amount of minimum free space.

  If the free space on the volume in which Deduplication Store is configured goes below 10% of the total space in the volume, deduplicated jobs will fail.

• Free Space Warning (MB)

  Specifies the amount of free space in the volume in which deduplication store is configured at which a warning must be generated. If the amount of free space falls below the specified amount, the system generates an event message and generates the MediaAgents (Disk Space Low) alert, if configured.

• Minimum Size of Deduplicable Object

  Specifies the minimum size of a deduplicated object. Objects below the specified minimum size will not be deduplicated. If necessary, use the space to modify the minimum size. This option is not available when deduplication is selected at the block level.

• Do not Deduplicate against objects older than

  Specifies the minimum period of time that a file (or object) is used as the primary object for any new secondary object. Setting a period will ensure that very old objects are not allowed as the 'origin' data for newer data protection jobs that are deduplicated. If necessary, use the space to modify the age of the primary file.

  To obtain optimal results, we recommended that the values for Minimum Size of Deduplicable Object and Do not Deduplicate against objects older than are not set below the default values.

• Enable software compression with Deduplication

  Select this option to enable software compression on the storage policy copy when performing deduplication.

• Deduplication Type

  Displays the details of the deduplication enabled on the copy. The deduplication details can be configured at the storage policy properties.

  • Type

    Specifies the selected deduplication type.

  • Block level Deduplication factor (in KB)

    Block size to be used for block level deduplication. This is displayed only if the Deduplication Type is selected at the block level.
