Pre & post processing capability

• Pre & post processing is typically used on clients for doing things like shutting down a database prior to a backup, and bringing up a database after a backup.



• The "Backup command:" field in a client definition must be "savepnpc".



• "savepnpc" is a standard program on NetWorker clients which will execute a named script prior to the client backup (pre-processing) and execute another named script after the client backup (post-processing).



• The scripts must be named in a configuration file resident on the client named /nsr/res/groupname.res where groupname is the name of the group to which the client belongs on the server.



• The format of the groupname.res file is
  
  

         type: savepnpc;
         precmd: /somedir/some_pre_script;
         pstcmd: /somedir/some_post_script;
         timeout: "4:00am";
       

  This timeout value means that if the backup has not completed by 4:00am, execute the post-command anyway. An alternative form for the timeout line is
  
  

         timeout: "3 hours";
       

  This form of the timeout means that if the backup has not completed by 3 hours after the pre-command completes, execute the post-command anyway.
  
  Timeout lines are optional - if one is not used, the post-command will not execute until the backup completes, regardless of how long it takes.
