Environment Variable Description Used In Default Value
TYPE Species the type of backup and restore application. The valid values
are:
• dump: NDMP server generates inode-based le history
• tar: NDMP server generates le based le history

Restore
dump
FILESYSTEM Species the path to be used for the backup. The path must be a
directory.
Backup None
LEVEL Species the dump level for the backup operation. The valid values
are 0 to 9.
Backup 0
HIST Species how le history is to be generated. The valid values are:
• d: Species that node/dir-format le history will be generated
• f: Species that le-based le history will be generated
• y: Species that the default le history type (which is the
node/dir format) will be generated
• n: Species that no le history will be generated
Backup y
DIRECT Species whether the restore is a Direct Access Retrieval. The valid
values are Y and N.

Restore
Y
UPDATE Species whether the dump level and dump time for a backup
operation should be updated on the NDMP server so subsequent
backups can reference the dump level from previous backups. The
valid values are Y and N.
Backup Y
EXCLUDE Species a pattern for matching to directory and le names that are
not to be backed up. This environment variable is a list of strings
separated by commas. Each entry is matched against nodes
encountered during backup. The string can contain an asterisk (*) as
the wildcard character, but the asterisk must be the rst or last
character of the pattern. A maximum of 32 comma-separated strings
are supported.
Backup No exclude

RECURSIVE Species whether the restore should be recursive. The valid values
are Y and N. If this environment variable is set to N, only les that are
the immediate children of the restore target are restored.
Restore Y
RESTORE_OVERWRITE Species whether the restore operation should overwrite existing les
with the backup data. The valid values are Y and N.
Restore Y
LISTED_INCREMENTAL Species whether an additional directory listing is added to the
backup stream during incremental backup so that the restore
operation can handle les and directories deleted between the
incremental backups. This environment variable controls behavior
similar to the "listed incremental" option of the tar application. The
valid values are Y and N.
During backup, if this variable is set to Y, an additional directory listing
is added to the backup data stream. Because of the additional
processing required, this option could impact the backup data stream
size and performance.
During restore, if this variable is set to Y and the backup data stream
was generated with this variable set to
Y, the NDMP server will
handle deleting les and directories that are deleted between
incremental backups. Setting this variable to Y requires additional
processing time and increases the backup data stream size (the size
of the increase depends on the number of elements in the backup
