Environment Variable Description Used In Default Value
TYPE Species 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 Species the path to be used for the backup. The path must be a
directory.
Backup None
LEVEL Species the dump level for the backup operation. The valid values
are 0 to 9.
Backup 0
HIST Species how le history is to be generated. The valid values are:
• d – Species that node/dir-format le history will be generated
• f – Species that le-based le history will be generated
• y – Species that the default le history type (which is the
node/dir format) will be generated
• n – Species that no le history will be generated
Backup y
DIRECT Species whether the restore is a Direct Access Retrieval. The valid
values are Y and N.

Y
UPDATE Species whether the dump level and dump time for a backup
operation should be updated on the NDMP server so that subsequent
backups can reference the dump level from previous backups. The
valid values are Y and N.
Backup Y
EXCLUDE Species 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 Species 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 Species whether the restore operation should overwrite existing les
with the backup data. The valid values are Y and N.
Restore Y
LISTED_INCREMENTAL Species 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
