representative.
PDALIGN
Specifies the number of minutes before the
optimized duplication times out. Indicated in
minutes. The value expressed

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.
N/A N/A SEGKSIZE
Determines the smallest size file (in KBs) that
NetBackup segments. Files smaller than the
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.
From 1 to the
practical system
limit 16 MINFILE_KSIZE
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.
1 (on) or 0 (off) 1 MATCH_PDRO
Determines the maximum bandwidth that is
allowed for optimized duplication. The value is
specified in KBytes/second. 0 (no limit) to the
