NAME
       NSR Layout - NetWorker file layout

DESCRIPTION
       The NetWorker server filesystem has a directory called /nsr that con­
       tains log files, on-line indexes and configuration information.  This
       directory can be created in any filesystem with /nsr set up as a sym­
       bolic link to the actual directory.  The format of this directory is
       as follows:


       /nsr/logs
              Contains server logging messages.  The files in this directory
              are in ASCII format.

       /nsr/res
              Contains the configuration files for various components of the
              NetWorker server. For example, the Jukebox daemon nsrjbd
              stores its configuration in /nsr/res/nsrjb.res.

       /nsr/cores
              Contains directories that correspond to the NetWorker server
              daemons.  Each directory may contain core files from NetWorker
              server daemons that have abnormally terminated.

       /nsr/mm
              Contains the media index.  Information about the contents of
              this index file can be printed with the nsrls(8) command.  See
              the mm(8) and mminfo(8) manual pages on how to view and manip­
              ulate the media index information.

       /nsr/index
              This directory contains subdirectories with names that corre­
              spond to the NetWorker clients that have saved files.  Each
              index directory contains files that allow the NetWorker server
              to provide an on-line database of the client's saved files.
              The most important file is the db file which contains the Net­
              Worker save records and access indexes to those records.  This
              index file grows with the number of files saved by the Net­
              Worker service.  Administrators should plan to use about 200
              bytes per saved file instance placed in this index.  An index
              may grow to a maximum of 1GB in size, with the first 40KB
              allocated for internal use.

              The format of the db file is subject to change, and is acces­
              sible only through an RPC interface to nsrindexd(8).  However,
              the command nsrls(8) can be used to obtain some useful statis­
              tics from this file.

              The existence of the db.SCAVENGE file indicates that the asso­
              ciated db file may need to be checked.  The nsrck(8) command
              is used for checking and rebuilding index files.  While check­
              ing is taking place, the db.SCAVENGE file may contain the save
              records that will be used to rebuild db.  If the filesystem

              does not have enough free space to contain db.SCAVENGE, then
              the file will be a symbolic link to a temporary file in some
              other local filesystem.

              The file db.RECOVER is where nsrck ``rebuilds'' a fresh index.
              Upon completion this file is renamed to db.

              The /nsr/index directory may also contain zero sized, zero
              permission files used as persistent, stable records of
              client's savesets to be removed from the on-line indexes.

       The executables for the NetWorker system are usually installed in the
       directory /usr/etc, though another location may be chosen when the
       nsrize(8) installation script is run.

       When executables for more than one architecture are installed, the
       non-native architectures are by default put in the directory
       /export/exec/arch/etc, where arch refers to a given architecture
       name.  A different location to install non-native executables can be
       chosen at installation time.


FILES
       /nsr                NetWorker indexes and log files.

       /usr/etc            Where NetWorker executables for the native archi­
                           tecture are normally installed.

       /export/exec/arch/etc
                           Where NetWorker executables for non-native archi­
                           tectures are normally installed.
