Variable Name Description Default
LISTED_INCREMENTAL This environment controls behavior similar to the “listed incremental”
option of the tar application. This variable specifies whether additional
directory listing is added to the backup stream during incremental
backup so that the recovery operation can handle files and directories
deleted between the incremental backups.
During backup, if this variable is set, additional directory listing will be
added to the backup data stream. Because of the additional process
required, this could affect the backup data stream size and
performance.
During recovery, if this variable is set and if the backup data stream was
generated with this variable turned on, NDMP server will handle deleting
files and directories that are deleted between incremental backups.
Setting this variable requires additional processing time and enlarges
the backup data stream size (how much it change will depend on the
number of elements in the backup data set). If this feature is not
important to the end user, it should not be set.
N
BASE_DATE This variable is used by TSM for token-based backup, as an alternative
to using the LEVEL environment variable.
When BASE_DATE is set to “0”, a full backup is performed.
After a full backup completes, a token can be retrieved by retrieving the
DUMP_DATE environment variable. This token can then be passed in
later backup as value of BASE_DATE. The backup performed in this case
will be an incremental backup relative to the time when the token was
generated.
When BASE_DATE is set to “-1”, token-based backup is disabled.
-1
DEREF_HARD_LINK This environment variable controls whether hard link files data content
are backed up for all instances of the same file. Valid values are “Y” and
“N”. N
