Administrator Guide

NOTE: Your environment should allow ICMP (ping) trac between the FluidFS controllers’ private IP addresses (not the access
VIPs) and the backup server.
Table 19. 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 19. 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.
N
