Introduction - Replication Software for PC Servers and Workstations
===================================================================
Enables swift multiple replication of ANY PC Server or Workstation
regardless of operating system, from any drive letter obtained on
the Network.

Reduces the labor time it takes to replicate servers from hours
to seconds.

Enables non-technical operators to restore any number of servers
or workstations simultaneously via the network.

Creates a complete hard drive image which is stored as a file
containing every byte on the hard drive, including; FDISK,
FORMAT, CMOS, Configuration, Operating System, and all
applications and related data contained on the drive.

SnapBack DUP software is a simple, trouble-free application
designed to create a precise image backup of a Server or
Workstation hard drive, for the purpose of swift, accurate,
system replication.  The user interface is designed so that a
novice can perform a complete backup that contains every byte on
the drive.  Simply insert a floppy, turn on the computer, and
replicate a complete system automatically.  No need to even
format the drive!  Additionally, the images are stored as files
on the network so you can easily manage multiple images and have
instant access to any number of Server or Workstation images.

SnapBack DUP makes building complex systems a Snap!  Since there
is no operating system, network, or restoration experience
required, any number of workstations or servers containing new
unformatted hard drives can be built by a novice with only a
single floppy.

SnapBack DUP is backed by our eight years of SCSI technology
experience and excellent technical support.  You can be assured
that SnapBack DUP will deliver the performance and reliability
you need to create, store, and replicate your network servers and
workstations.

Installing SnapBack DUP
=======================
NOTE:  You must INSTALL and run SnapBack DUP from DOS 6.x or
below.  Do not run from a multitasking operating system such as
OS/2, Windows, Windows 95, etc.  If you attempt to INSTALL from
within Windows 95, the default configuration files must be
changed to operate properly.  If you are running Novell Netware
MAP ROOT, and Microsoft Windows 95's DOS 7, you will have to
change the default drive in the SnapDup configuration to point to
the correct drive.  If you backup from within Windows 95, your
disk may be changing during the backup, and you will not have an
accurate image.

Insert the diskette in drive A:  ( or B:  ) and change to that
drive letter and type INSTALL.  When install asks for the
destination drive, choose your NETWORK drive letter, not your
local drive C:.  This is very important, as SnapBack DUP is
designed to be run from the network drive, not the local drive,
because you can only restore FROM your network drive.

Making Your Backup Master
=========================
Go to the network drive you installed SnapBack DUP in.  Go to the
directory \SNAPDUP and type in SNAPDUP.  SnapBack DUP will now
ask you to name a new backup image, or use an existing one.  Just
put a meaningful name for your backup set in the name field.  We
will use this name to identify your backup image and assign a
unique backup image filename.  We store both names in a file
named USERS.CTL.  We then name all backup images done in this
session by this filename.  If you need to make multiple backup
masters, then you must enter SNAPDUP again and specify a
different backup image filename.

Next, if you have not made a boot floppy, SnapBack DUP prompts
you to do so.  We suggest you skip this step until you are ready
to make master boot floppies for production restores (see
explanation of MAKEBOOT.EXE below).  When you get to the main
menu, there will be a window to the right side of the screen
called configuration settings.  This window tells you about the
current settings, and the destination of the image file, make
sure it points to your network drive.

To change the destination, go to configuration, then to Change
Default Drive, and select the drive where you want the image
stored.  Make sure to save the settings, if you plan to use these
settings for all future backups.  To do a backup, select Backup
from the main menu, then select the option you want.  It is not
necessary to select the unpartitioned area of the drive unless
you want every single byte of the hard drive in the image file.
If everything works properly, you should now be doing a backup.

Restoring
=========
Before attempting to restore, create a boot floppy image using
MAKEBOOT.EXE.  We have included this program, which will assist
you in making a boot floppy that can connect to the network with
no operational hard drive.  If you are going to be using the AUTO
restore feature, which will NOT PROMPT THE USER BEFORE BEGINNING
THE RESTORE, then you should make an AUTOEXEC.BAT file that
specifies the backup image filename to be used (see below).  A
copy of the floppy is then automatically copied to the network
for later use.  If necessary, you can then use COPYFLOP.EXE,
which makes a new boot floppy from the saved network boot floppy
image.  These programs may not work properly under Windows 95's
DOS 7.

To invoke automatic restore operations, start SnapBack DUP with
an AUTOEXEC.BAT containing the following:

SNAPDUP /RESTOREAUTO /F:(your image filename) This will prompt
the user before beginning the restore.

SNAPDUP /RESTOREAUTO /DANGERNOWARNING /F:(your image filename)
Does NOT prompt the user before beginning the restore.

Naming and Using Backup Images
==============================
SnapBack DUP uses the backup image filename generated at login.
This filename is also displayed on the main menu and will be used
in both the backup or restore operations.  To insure that you
name your images properly and restore the correct images, always
specify an image name using the /F:  switch when invoking
SnapBack DUP.  This specifies which filename to use for any
backup or restores used in this session.  Using the /F:  switch
also insures that you are restoring the proper image.  When
specifying the filename, only give the first 8 characters, do not
include the period or extension. ie:  SnapBack /F:90123aac or
SnapBack /F:Comp1.  The Filename must be 8 characters or less.

Configuration File
==================
SnapBack uses a file called SNAPBACK.NET to store drive
configurations.  This file is created by the install program, but
may be modified in the SnapBack configuration menu or with any
text editor.  For example, to burn a CD-ROM, the format of this
file is:

Network Drives                            Local Drives or CD-ROM's
[Network]                                 [Network]
Master = Server/Volume:                   Master = Drive x:
Floppy = Server/Volume:                   Floppy = Drive x:
Start = Server/Volume:                    Start = Drive x:

[Network] is a sub heading, IT IS required.

MASTER = is the drive where all user information is stored i.e.,
the drive backup image filename, user name, configuration
settings, etc.

FLOPPY = is the drive where all bootable floppy images are stored

START = is the drive where all backup images are stored.

SERVER/VOLUME:  is the server name and volume name, for example:
Master = CDP/SYS:  would specify that the files go to server CDP,
on volume SYS.  This is so SnapBack can find the right drive,
regardless of the drive mappings.

DRIVE X indicates the drive letter where the files are stored.
For example:  Master = Drive E:  would put the files on drive E:

Management Tool (NETSTAT.EXE)
=============================
Netstat is a Windows tool which provides statistics and log
files for each backup and restore operation.  This can be used
for monitoring production and insuring that the restores were
successful, and accounting on an annual and monthly basis.
