DESCRIPTION
nsrndmp_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
details.
The status of a backup can be monitored using the Java based
NetWorker Management Console
or the
curses(3X)
based
nsrwatch(1m)
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
available at
www.ndmp.org
for more details.
Details about handling media are discussed in
nsrmm(1m)
and
nsr_device(5).
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).
OPTIONS
- -c client-name
-
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
nsr_client(5).
- -M
-
An NDMP client will be backed up to a NetWorker storage node by the
nsrdsa_save
program. This option provides most of the NetWorker storage node features, such as backup to disk, multiplexing, automedia verification, and staging. The
nsrndmp_save
program spawns
nsrdsa_save
locally.
A NetWorker storage node hostname should be listed in the "storage nodes" attribute of server's
client-name
resource.
Notes:
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 (1m)
for more details.
- -P proxy-host
-
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 receive the data and save it to NetWorker storage device. This option is valid only with -M.
- -I index-host
-
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 designated to perform NDMP backup initiation and index processing. This host must have 'Operate NetWorker' privileges.
- -g group
-
Is used by
savegrp(1m)
and
savefs(1m)
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.
- -l level
-
Indicates the level of the save. This option is used by
savegrp(1m)
and
savefs(1m)
to specify a particular level for a scheduled save.
- -b pool
-
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 savetime=number'', where number is the savetime of the
save set created by this backup. Used by
savegrp(1m).
- -m masquerade
-
Specifies the tag to precede the summary line.
This option is used by
savegrp(1m)
and
savefs(1m)
to aid in savegrp summary notifications.
- -n
-
Indicates no save. Not supported, but provided for compatibility.
- -N name
-
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.
- -s server
-
Specifies which machine to use as the NetWorker server.
- -J storage-node
-
Specifies which machine to use as the NetWorker storage node.
- -t date
-
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(1m)
and
savefs(1m)
to perform scheduled saves by consulting with the media database to
determine the appropriate time value based on the previous saves for the
save set and the level of the scheduled save.
- -T backup-type
-
The type of backup on the NDMP server, for example
celestra.
- -e expiration
-
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 recyclable.
The special value
forever
is used to indicate that a volume that never expires (i.e. an archive or a
migration volume) must be used.
By default, no explicit expiration date is used.
- -w browse
-
Sets the date (in
nsr_getdate(3)
format) after which the saved data will no longer be browsable.
By default, the server determines the browse date for the
save set based on the browse policies in effect.
This option
allows overriding the existing policies on a save-by-save basis.
- -y retention
-
Sets the date (in
nsr_getdate(3)
format) when the saved data will become recyclable.
The special value
forever
is used to indicate that a volume that never expires (an archive or a
migration volume) must be used.
By default, the server determines this date for the
save set based on the retention policies in effect.
This option
allows overriding the existing policies on a save-by-save basis.
- -W width
-
The width used when formatting summary information output.
