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 Species 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 Species the path to be used for backup. The path must be a directory. Not applicable
LEVEL Species the dump level for the backup operation. Valid values are 0 to 9.
0
HIST Species how le history is to be generated. The supported values are d, f,
y, and n.
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.
Y
DIRECT Species whether the restore is a Direct Access Retrieval. 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. Valid values Y and N.
Y
EXCLUDE Species 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 Species 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 Species 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 species 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 aect the backup data stream size and performance.
