Configuring deduplication | 63 |
Reconfiguring the deduplication storage server and storage paths |
|
| Table | pd.conf file values (continued) | |
Setting | Default value | Possible values | Action |
OPTDUP_ENCRYPTION | 1 | 1 (on) or 0 (off) | Determines if the data to replicate is encrypted |
|
|
| before it is sent out over the network. |
DONT_SEGMENT_TYPES | N/A | Any file extension | Allows a list of file name extensions to be |
|
|
| specified. Files in the backup stream that have |
|
|
| these extensions are given a single segment if |
|
|
| smaller than 16MB. Larger files are deduplicated |
|
|
| using the maximum 16MB segment size. |
|
|
| Example: |
|
|
| DONT_SEGMENT_TYPES = mp3,avi |
|
|
| This setting prevents NetBackup from analyzing |
|
|
| and managing segments within the file types |
|
|
| that do not deduplicate globally. |
BANDWIDTH_LIMIT | 0 | 0 (default - no limit) | Determines the maximum bandwidth that is |
|
| to the practical | allowed when backing up or restoring data |
|
| system limit | between the media server and the deduplication |
|
|
| pool. The value is specified in KBytes/second. |
|
|
| The default is no limit. |
MAX_IMG_MBSIZE | 50,000 | 0 to 50,000 | This keyword is reserved for internal use. |
|
|
| Note: Do not change this setting unless directed |
|
|
| to by a Symantec representative. |
Reconfiguring the deduplication storage server and storage paths
Only one deduplication storage path can exist on a media server. Therefore, you cannot rerun the StorageServerConfigurationWizard. An activated NetBackup Deduplication Engine rejects all configuration attempts that abandon its previously defined storage and backup images. You must manually deactivate the engine and physically delete the storage directory.
Two aspects to the configuration exist: the record of the deduplication storage in the EMM database and the physical presence of the storage on disk (the populated storage directory). Deleting the deduplication storage server does not alter the contents of the storage on physical disk. To protect against inadvertent data loss, NetBackup does not automatically delete the storage when you delete the storage server.
