NAME
     nsr_layout - NetWorker file layout

SYNOPSIS
     type: NSR layout

DESCRIPTION
     The NetWorker server filesystem has a directory called  /nsr
     that  contains log files, on-line indexes, and configuration
     information.  This directory can be created in any  filesys-
     tem with /nsr set up as a symbolic link to the actual direc-
     tory (this is determined at installation time).  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 server stores
          configuration files in /nsr/res/nsrdb.

     /nsr/mm
          Contains the media index.  Information about  the  con-
          tents  of  this  index  file  can  be  printed with the
          nsrls(1m) command.  See the  nsrmm(1m)  and  mminfo(1m)
          manual  pages  on  how to view and manipulate the media
          index information.

     /nsr/index
          This directory contains subdirectories with names  that
          correspond  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
<snip>

   The files in the db6 directory include the files listed
          below.   Note that these files are for the internal use
          of the server and are not to be modified or changed for
          any purposes.

          <savetime>.rec
               These files contain the  index  records  for  each
               file  saved at the savetime, where <savetime> is a
               hexadecimal representation of the time.

          <savetime>.k0
               These files contain the keys on the <savetime>.rec
               file based on file name.

          <savetime>.k1
               These files contain the keys on the <savetime>.rec
               file  based  on  inode.   These may be zero length
               files if the client file index is  for  a  windows
               client.
