NOTE: Your environment should allow ICMP (ping) traffic between the FluidFS controllers’ private IP addresses (not the
access VIPs) and the backup server.
Supported NDMP Environment Variables on page 435 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 21. Supported NDMP Environment Variables
Variable Name Description Default
TYPE Specifies the type of backup/restore application. Valid values are dump
and tar, and are case sensitive.
dump – NDMP server generates inode-based file history.
tar – NDMP server generates file-based file history.
dump
FILESYSTEM Specifies the path to be used for backup. The path must be a directory. Not applicable
LEVEL Specifies the dump level for the backup operation. Valid values are 0 to 9.
0
HIST Specifies how file history is to be generated. The supported values are d,
f, y, and n.
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.
Y
DIRECT Specifies whether the restore is a Direct Access Retrieval. Valid values are
Y and N.
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. Valid values Y and N.
Y
EXCLUDE Specifies a pattern for file or directory names that are not to be backed up.
The pattern is a comma-separated list of file 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 Specifies whether the restore should be recursive or not. Valid values are
Y and N. If this variable is set to N, only the files that are the immediate
children of the restore target are restored.
Y
RESTORE_OVERWRITE Specifies whether the restore operation should overwrite existing files 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 specifies whether an additional directory listing
N
