Table 15. Supported NDMP Environment Variables describes the NDMP environmental variables that are supported by FluidFS. Refer
to the Data Management Application (DMA) documentation for a listing of the variables supported by DMA. If DMA does not set any
of the variables, the NDMP server operates with the default value.
Table 15. Supported NDMP Environment Variables
Variable Name Description Default
TYPE Species the type of backup/restore application. Valid values are dump and
tar, and are case sensitive.
dump – NDMP server generates inode-based le history.
tar – NDMP server generates le-based le history.
dump
FILESYSTEM Species the path to be used for backup. The path must be a directory. Not applicable
LEVEL Species the dump level for the backup operation. Valid values are 0 to 9.
0
HIST Species how le history is to be generated. The supported values are d, f,
y, and n.
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.
Y
DIRECT Species whether the restore is a Direct Access Retrieval. Valid values are Y
and N.
Y
UPDATE Species 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. Valid values Y and N.
Y
EXCLUDE Species a pattern for le or directory names that are not to be backed up.
The pattern is a comma-separated list of le or directory names, up to 32.
Each name will be used to match to nodes encountered during backup. A
name can contain an asterisk (*)as the wildcard character. The comma (,) or
backslash (\ )characters in a name should be escaped with a backslash.
No default
RECURSIVE Species whether the restore should be recursive or not. Valid values are Y
and N. If this variable is set to N, only the les that are the immediate children
of the restore target are restored.
Y
RESTORE_OVERWRITE Species whether the restore operation should overwrite existing les with
the backup data. Valid values are Y and N.
Y
LISTED_INCREMENTAL Controls behavior similar to the listed incremental option of the tar
application. This variable species whether an additional directory listing is
added to the backup stream during incremental backup so that the recovery
operation can handle les and directories deleted between the incremental
backups.
During backup, if this variable is set, an additional directory listing is added to
the backup data stream. Because of the additional process required, this
addition could aect the backup data stream size and performance.
