NAME
       empolbak - perform on-line backup of an Empress database

SYNOPSIS
       empolbak [-b] [-f] [-v] [blocksize] [file] database

DESCRIPTION
       Online backup is a procedure designed to allow the database administra-
       tor to back up the database to an offline medium without  stopping  all
       database  activity.  empolbak  is responsible for performing the backup
       and for coordinating all updates including those involved  in  transac-
       tions.

       Note  that all options must be specified before the arguments of any of
       the options, and that the arguments must be specified in the same order
       as the options.

       -b        Use  the  next argument as the blocking factor for tape back-
                 ups; each block is 512 bytes.

       -f        Use the next argument as the name of the backup file or  tape
                 device.

       -v        Verbose.   Normally,  empolbak  does its work silently.  When
                 this option is specified, empolbak displays each phase of the
                 backup as it is started, as well as the name of each database
                 file as it is archived.
