Setting	Default value	Possible values	Action
PDALIGN			This keyword is reserved for internal use.
			Note: Do not change this setting unless directed
			to by a Symantec Technical Support
			representative.
OPTDUP_TIMEOUT	N/A	The value expressed	Specifies the number of minutes before the
		in minutes	optimized duplication times out. Indicated in
			minutes.
SEGKSIZE	N/A	N/A	This keyword is reserved for internal use.
			Warning: Changing this value can reduce
			capacity and decrease performance. Modify this
			setting only if directed to do so by Symantec
			support representative.
MINFILE_KSIZE	16	From 1 to the	Determines the smallest size file (in KBs) that
		practical system	NetBackup segments. Files smaller than the
		limit	threshold are combined into a single large
			segment to reduce the overhead of managing
			many small segments. However, such segments
			have less chance of being deduplicated.
			Caution: Large numbers of files smaller than
			the threshold may adversely affect backup
			performance.
MATCH_PDRO	1	1 (on) or 0 (off)	Specifies that NetBackup should use the
			PureDisk Remote Office Agent dynamic
			segmentation deduplication algorithm. Enabling
			it means that the data that is backed up is
			globally deduplicated with each other. If disabled
			(set to 0), PDDO uses a static 128KB
			segmentation algorithm for deduplication.
			Caution: Changing the default segmentation
			algorithm most likely causes the next set of
			backups to not deduplicate with the existing
			storage pool data. Subsequent backups then
			deduplicate using the PDRO algorithm.
OPTDUP_BANDWITH	0	0 (no limit) to the	Determines the maximum bandwidth that is
		practical system	allowed for optimized duplication. The value is
		limit	specified in KBytes/second.
