DESCRIPTIONnsrndmp_save coordinates the backup process with NetWorker and a target
Network Data Management Protocol(NDMP) system. Only the super-user may
run this command. The user must specify a backup type, client-name,
server, and path.
The behavior of the backup depends on the NDMP system being protected.
Certain environment variables may be needed depending upon the target
system. Documentation for such backups should be consulted for more
The status of a backup can be monitored using the Java based NetWorker
Management Console or the curses(3X) based nsrwatch(8) program for
other terminal types.
nsrndmp_save is not responsible for moving data on the NDMP system.
All such activity is handled by the NDMP system. nsrndmp_save receives
messages from the NDMP system and processes them appropriately. Such
messages could request a new tape be mounted or a file index entry to
be created. Refer to the NDMP specification and documentation avail‐
able at www.ndmp.org for more details.
Details about handling media are discussed in nsrmm(8) and
In order to save data for another system, make sure the user performing
the nsrndmp_save operation is on the remote access attribute list of
the client resource. See nsr_client(5).
Specifies the client name for starting the save session. This
is useful on clients with multiple network interfaces, and hence
multiple host names. It can be used to create multiple index
databases for the same physical client. Note that this does not
specify the network interface to use. This is specified in the
server network interface attribute of the client resource. See
-M An NDMP client will be backed up to a NetWorker storage node by
the nsrdsa_save program. This option provides most of the Net‐
Worker storage node features, such as backup to disk, multiplex‐
ing, automedia verification, and staging. The nsrndmp_save pro‐
gram spawns nsrdsa_save locally. A NetWorker storage node host‐
name should be listed in the "storage nodes" attribute of
server's client-name resource.
Save sets that are backed up by nsrndmp_save via nsrdsa_save
will be treated as regular NetWorker save set and will have save
set flags as 'N' and 's'. 'N' indicates NDMP client and 's'
indicates backed up to NetWorker storage node. See mminfo (8)
for more details.
nsrndmp_save spawns nsrdsa_save on Proxy-host. Proxy-host must
be a valid NetWorker client and should be listed in the remote
access list of client-name resource. This host will act as a
proxy to NDMP Data Server to recieve the data and save it to
NetWorker storage device. This option is valid only with -M.
Used by savegrp to spawn nsrndmp_save on Index-host. Index-host
must be a valid NetWorker client and should be listed in the
remote access list of client-name resource. This host is desig‐
nated to perform NDMP backup initiation and index processing.
This host must have 'Operate NetWorker' privileges.
Is used by savegrp(8) and savefs(8) to denote the group of the
save. See nsr_client(5) and nsr_group(5). It is also used by
the NetWorker server to select the specific media pool.
Indicates the level of the save. This option is used by save‐
grp(8) and savefs(8) to specify a particular level for a sched‐
Specifies a particular destination pool for the save.
-L When two -L options are specified, this option causes an extra
line to be printed at the end of the form ``complete save‐
time=number'', where number is the savetime of the save set cre‐
ated by this backup. Used by savegrp(8).
Specifies the tag to precede the summary line. This option is
used by savegrp(8) and savefs(8) to aid in savegrp summary noti‐
-n Indicates no save. Not supported, but provided for compatibil‐
Indicates the symbolic name of this save set. By default, the
most common prefix of the path arguments is used as the save set
name. The indexes get stored against the actual path name.
-q Indicates quiet. Not supported, but provided for compatibility.
Specifies which machine to use as the NetWorker server.
Indicates the date (in nsr_getdate(3) format) after which files
must have been modified before they will be saved. This option
is used by savegrp(8) and savefs(8) to perform scheduled saves
by consulting with the media database to determine the appropri‐
ate time value based on the previous saves for the save set and
the level of the scheduled save.
The type of backup on the NDMP server, for example celestra.
Set the date (in nsr_getdate(3) format) when the saved data will
expire. When a save set has an explicit expiration date, the
save set remains both browsable and non-recyclable until it
expires. After it expires and it has passed its browse time,
its state will become non-browsable. If it has expired and it
has passed its retention time, the save set will become recy‐
clable. The special value forever is used to indicate that a
volume that never expires (i.e. an archive or a migration vol‐
ume) must be used. By default, no explicit expiration date is
Sets the date (in nsr_getdate(3) format) after which the saved
data will no longer be browsable. By default, the server deter‐
mines the browse date for the save set based on the browse poli‐
cies in effect. This option allows overriding the existing
policies on a save-by-save basis.
