Environment Variable Description Used In Default
Value
TYPE Specifies the type of backup and restore application. The valid
values are:
● dump – NDMP server generates inode-based file history
● tar – NDMP server generates file-based file history
Backup
and
Restore
dump
FILESYSTEM Specifies the path to be used for the backup. The path must be a
directory.
Backup None
LEVEL Specifies the dump level for the backup operation. The valid values
are 0 to 9.
Backup 0
HIST Specifies how file history is to be generated. The valid values are:
● d – Specifies that node/dir-format file history will be generated
● f – Specifies that file-based file history will be generated
● y – Specifies that the default file history type (which is the
node/dir format) will be generated
● n – Specifies that no file history will be generated
Backup y
DIRECT Specifies whether the restore is a Direct Access Retrieval. The
valid values are Y and N.
Backup
and
Restore
Y
UPDATE Specifies 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 Specifies a pattern for matching to directory and file 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 first or
last character of the pattern. A maximum of 32 comma-separated
strings are supported.
Backup No exclude
pattern is
specified by
default
RECURSIVE Specifies whether the restore should be recursive. The valid values
are Y and N. If this environment variable is set to N, only files that
are the immediate children of the restore target are restored.
Restore Y
RESTORE_OVERWRITE Specifies whether the restore operation should overwrite existing
files with the backup data. The valid values are Y and N.
Restore Y
LISTED_INCREMENTAL Specifies whether an additional directory listing is added to the
backup stream during incremental backup so that the restore
operation can handle files 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 files 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 data set). If this feature is not important in your
environment, this variable should not be set.

BASE_DATE Specifies whether a token-based backup is performed. Token-
based backup is used by Tivoli Storage Manager as an alternative
