nsrndmp_recover

SYNOPSIS

       nsrndmp_recover [ -c client ] [ -s server ] [ -R recover-target ] {  -r
       raw  device    -S  ssid    -m  mount point [  -v { on|off } ] [ paths [
       paths...  ] ]  | -F }

DESCRIPTION

       nsrndmp_recover is used to coordinate recover operations with NetWorker
       and  a  Network  Data Management Protocol(NDMP) system. Only the super-
       user may run this  command.   There  are  two  ways  to  recover  data:
       destructive  recovers  and  file-level  recovers.  Destructive recovers
       occur when a raw partition is specifed by the -r option  along  with  a
       save  set id (-S) option.  Only a single save set can be specified at a
       time since the target raw device pathname must be specified.  Users may
       opt  to  use  the administrative user interface, nwadmin(1), to perform
       the destructive recover operation through the save set recover  window.
       Users  can  determine  save  set  ids  using the user interfaces or the
       mminfo(1) command.  File level recovers are specified by the -F  option
       in conjunction with the use of the nwrecover(1) or recover(1) commands.
       Users should not specify this option.

       The status of a recover can be monitored using  the  X  Window  System-
       based  nwadmin(1)  program  or the curses(3X) based nsrwatch(1) program
       for other terminal types.  Only volume information is available at this
       time.  The amount of data that has been recovered is not provided.

       nsrndmp_recover  is not responsible for moving data on the NDMP system.
       All such activity is  handled  by  the  NDMP  system.   nsrndmp_recover
       receives  messages  from  the  NDMP system and processes them appropri-
       ately.  Such messages could request a new tape be mounted or to post  a
       log  message.  Refer to the NDMP specification and documentation avail-
       able at www.ndmp.org for more details.

       In order to recover data for another system, make sure  the  user  per-
       forming the nsrndmp_recover operation is on the remote access attribute
       list of the client resource. See nsr_client(5).

OPTIONS

       -c client
              Client is the name of the machine that saved the files.

       -F     Specifies that a file-level recovery is going to  be  performed.
              This   option  should  only  be  specified  by  nwrecover(1)  or
              recover(1).

       -m mount point
              The mount point of the raw device specified by  the  -r  option.
              The  filesystem  will be unmounted for the recover operation and
              mounted after the operation is complete.

       -r raw device

       -s server
              This option selects which NetWorker server to use.

       -S ssid
              This mandatory option is used to specify save set recover  mode.
              This  mode  can  be  used  to implement fast batch file recovery
              without requiring the NetWorker file index entries.  ssid speci-
              fies  the  save  set  id for the save set to be recovered.  When
              there are multiple clone instances for a save set,  the  cloneid
              can also be specified to select the particular clone instance to
              be recovered from.
                    When no path arguments are specified, the entire save  set
              contents  will  be  recovered. One or more path arguments can be
              specified to limit which  directories  and  files  are  actually
              recovered.  If path arguments are supplied, then the begining of
              each path name as it exists in the save set must  exactly  match
              one  of  the  path  before it will be recovered. Shell like file
              name, matching using meta characters like '*', '?', and '[...]',
              is not supported.

       -v on|off
              This  option specifies the value of the verify flag. If the ver-
              ify flag is turned on then, prior to sending to ndmp server  for
              recovery, the paths would be verified as having existance in the
              index database for the given Save set  id.  Only  those  entries
              that  are  found in the index database would be sent to the NDMP
              server for recovery. On other hand if verify flag  is  off  then
              paths  would be sent across to the NDMP server without verifica-
              tion.  The default value of this flag is on.

DIAGNOSTICS

       Skipping file due to incomplete save set: /core
              The user has marked a file that is associated with an incomplete
              save  set.   The  user  should run nsrim -X to resynchronize the
              file index and media database.

       Entry /core not found in index, skipping
              The user specified directory / file (/core) in  path  arguments,
              which  could not be found in the index database. The user should
              run nsrndmp_recover with -v off from the command  line  if  this
              check is wished to bypass. This can be useful if the indexes are
              lost and the data exists in backup media.
