Use this dialog box to view the properties of the data path and to establish the data compression, hardware encryption and chunk and block sizes for the data path.
MediaAgent
The name of the MediaAgent used by the data path.
Library
The name of the library used by the data path.
Drive Pool
The name of the drive pool used by the data path.
Scratch Pool
The name of the scratch pool used by the data path.
Enabled
Indicates whether the data path is enabled or not.
Silo
Indicates whether the data path is configured for Silo storage.
Index Cache
The name of the Index Cache used by the data path.
Hardware Compression
If selected, hardware data compression is established for all data that is backed up through the data path. Hardware compression has priority over the software compression mode, which is established in the Storage Device (Data Transfer Option) dialog box in the Subclient Properties. (This option only applies when the library associated with the data path is a tape library.)|
|
It is recommended that a full backup is performed on all the subclients associated with the storage policy copy, whenever you change the compression format to ensure that synthetic full jobs complete successfully. |
Use Hardware Encryption
If selected, hardware encryption of data will be enabled if the tape drives associated with the data path support encryption.
|
|
Enable this option only when the drives associated with the data path support encryption. If this option is enabled and the hardware does not support encryption, jobs using the data path will fail. |
Chunk size
Specifies that the data path will use the chunk size configured for the agent in the Chunk Size tab of the Media Management Configuration dialog box available in the Control Panel. (Applies only to tape media; for disk and optical media the system by default uses 2 GB as the chunk size.)
Specifies that the data path will use the specified value as the chunk size. This value will override the chunk size configured for a specific Agent, and the default for the disk and the optical media. Use the space to type the new value.
Block Size
Specifies that the data path will use a fixed block size of 64K to read/write to all media types.
Specifies that the data path will use the specified value as the block size. There are several considerations associated with changing the block size. See Performance Tunables for Media Management in Books Online for a comprehensive information on changing block sizes.
On disk libraries to Centera Clusters a block size of 32K is always used and user-defined block sizes are not applicable.
