DESCRIPTION

You can use the Deduplication command with the Default and Show options to display the default values for each of the Deduplication parameters and the current parameter values, respectively. You can use the Deduplication Tune command to adjust the following parameters:

Table: Deduplication parameters and default values

Setting	Default value	Possible values	Action
BACKUPRESTORERANGE	N/A	Classless Inter-Domain Routing format or comma-separated list of IP addresses	Specifies the IP address or range of addresses of the local network interface card (NIC) for backups and restores.
BANDWIDTH_LIMIT	0	0 (no limit) to the practical system limit, in KBs/sec	Determines the maximum bandwidth that is allowed when backing up or restoring data between the media server and the deduplication pool. The value is specified in KBytes/second. The default is no limit.
COMPRESSION	1	0 (off) or 1 (on)	Specifies whether you want compression. Default is set to compress files. If you do not want compression, change the value to 0.
DONT_SEGMENT_TYPES	N/A	Any file extension	You can specify a list of comma-separated file name extensions. Files in the backup stream that have the specified extensions are given a single segment if smaller than 16 MB. Larger files are deduplicated using the maximum 16-MB 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.
ENCRYPTION	0	0 (off) or 1 (on)	Specifies whether to encrypt the data. Default is set to not encrypt files. If you want encryption, change the value to 1. If you set this parameter to 1 on all hosts, the data is encrypted during transfer and in the storage.
LOCAL_SETTINGS	0	0 (allow override) or 1 (always use local settings)	Specifies whether to allow the pd.conf settings of the deduplication storage server to override the settings in the local pd.conf file.
LOGLEVEL	0	An integer, 0 to 10 inclusive	Specifies the amount of information that is written to the log file. The range is from 0 to 10, with 10 being the most logging. Note: Only change this value if a Veritas representative directes you to do so.
MAX_IMG_MBSIZE	50,000	0 to 50,000, in MBs	The maximum backup image fragment size in megabytes. Note: Only change this value if a Veritas representative directes you to do so.
MAX_LOG_MBSIZE	500	0 to 50,000, in MBs	The maximum size of the log file in megabytes.
OPTDUP_BANDWIDTH	0	0 (no limit) to the practical system limit, in KBs/sec	Determines the maximum bandwidth that is allowed for optimized duplication. The value is specified in KBytes/second.
OPTDUP_COMPRESSION	1	0 (off) or 1 (on)	Specifies whether to compress optimized duplication data. Default is set to not compress files. If you want compression, change the value to 1.
OPTDUP_ENCRYPTION	0	0 (off) or 1 (on)	Specifies whether to encrypt the optimized duplication data. Default is set to not encrypt files. If you want encryption, change the value to 1. If you set this parameter to 1 on all hosts, the data is encrypted during transfer and on the storage.
OPTDUP_TIMEOUT	N/A	expressed in minutes	Specifies the number of minutes before the optimized duplication times out. Indicated in minutes.
WS_RETRYCOUNT	3	Integer	This parameter applies to the PureDisk Deduplication Option only. It does not affect NetBackup deduplication. The WSRetryCount parameter lets you configure the amount of retries that are attempted in case the Web service fails or times out.
WS_TIMEOUT	120	Integer	This parameter applies to the PureDisk Deduplication Option only. It does not affect NetBackup deduplication. The WSTimeout parameter lets you increase or decrease the timeout value for Web service calls made from NetBackup media servers to PureDisk storage units.

OPTIONS

Deduplication Defaults: Display the default values for the Deduplication parameters.

Deduplication Show: Display the current values for the Deduplication parameters.

Deduplication Tune BACKUPRESTORERANGE Addresses: Specify the IP addresses or range of addresses of the local network interface card for backup and restore. The Addresses variable contains an IP addresses list or a range of addresses.

Deduplication Tune BANDWIDTH_LIMIT Limit: The maximum bandwidth that is allowed when backing up or restoring data between the media server and the deduplication pool. The limit variable contains the maximum bandwidth limit. The value for this variable is in KBytes/second.

Deduplication Tune COMPRESSION Comp: Whether you want compression. The Compression variable lets you enable or disable compression. You enter either Enable or Disable.

Deduplication Tune DONT_SEGMENT_TYPES Append FileTypes: Append new file types to the list of file types that NetBackup does not analyze or manage segments. The FileTypes variable lists the file types.

Deduplication Tune DONT_SEGMENT_TYPES Change FileTypes: Change the whole list of file types. The FileTypes variable lists the file types.

Deduplication Tune ENCRYPTION Value: Specify whether you want to encrypt the data. Use the Value variable to enable or disable encryption. The values that you can enter are Enable or Disable.

Deduplication Tune LOCAL_SETTINGS Override: Whether to allow settings of the deduplication server to override the local settings. The Override variable determines whether to allow an override to occur. The values that you can enter in this field are AllowOverride or UseLocalSetting.

Deduplication Tune LOGLEVEL Value: The amount of information that is written to the log file. The Value variable sets the range from 0 to 10. A value of 10 provides the most logging.

Deduplication Tune MAX_IMG_MBSIZE Value: Set the maximum backup image fragment size. The Value variable contains the maximum size of the backup image fragment in megabytes. You can enter a value between zero and 50000.

Deduplication Tune MAX_LOG_MBSIZE Value: Set the maximum size of the log file. The Value variable contains the maximum size of the log file in megabytes. You can enter a value between zero and 50000.

Deduplication Tune OPTDUP_BANDWIDTH Value: The maximum bandwidth that is allowed for optimized duplication. The Value variable contains the maximum bandwidth in KBs/sec.

Deduplication Tune OPTDUP_COMPRESSION Value: Whether to compress the optimized duplication data. The Value variable lets you enable or disable compression. The values for this field are: Enable or Disable.

Deduplication Tune OPTDUP_ENCRYPTION Value: Whether to encrypt the optimized duplication data. The Value variable lets you enable or disable encryption. The values for this field are: Enable or Disable.

Deduplication Tune OPTDUP_TIMEOUT Time: The number of minutes before the optimized duplication times out. The Time variable is the number of minutes before the optimized duplication times out.

Deduplication Tune WS_RETRYCOUNT Count: The amount of retries that are attempted in case the Web service fails or times out. The Count variable is the amount of retries that are attempted in case the Web service fails or times out.

Deduplication Tune WS_TIMEOUT Time: The timeout value for Web service calls made from NetBackup media servers to PureDisk storage units. The Time variable is the timeout value for Web service calls made from NetBackup media servers to PureDisk storage units.
