Installing with Norton Desktop for Windows
==========================================

     If you have Norton Desktop for Windows and you install Norton
Backup for Windows, the Scheduler icon will appear in the Norton
Desktop Applications group instead of the Norton Backup group.      

COMPATIBILITY WITH NORTON BACKUP FOR DOS (VERSION 1.2 and 2.0)
==============================================================

     If you are a user of Norton Backup for DOS and are currently in 
the middle of a FULL/INCREMENTAL or FULL/DIFFERENTIAL backup cycle,
you should not have to interrupt that cycle and start over. In fact,
you should be able to use either product to create your next backup
volume.
     Symantec strongly recommends that you confirm you'll be able
to do this by using Norton Backup for Windows to restore some files 
that were backed up with Norton Backup 1.2 or 2.0 for DOS. If you
encounter any errors while restoring, there may be some limitation(s)
--either hardware or software--that inhibits compatibility with older
Norton Backup volumes. If this is the case, you should start the cycle
over by making a full backup of all your drives before resuming your
routine.
     Use enhanced ECC to make backup sets with Norton Backup for DOS that
can be restored with Norton Backup for Windows 1.2
     

Data Verification
-----------------
     If data verification in your setup file was set for "Read Only" in
Norton Backup for DOS, be sure to check your settings in Norton Backup
for Windows when you first load that setup file. The "Read Only" option
does not exist in Norton Backup for Windows and the setting will default
to "Read and Compare."  Change this setting if you prefer one of the
other options.


Macro Compatibility
-------------------
     If you plan to use setup files that were created with Norton Backup
for DOS, you will need to re-create any macros that were associated
with those setup files.


FLOPPY DRIVE SETUP
==================

Automatic Floppy Configuration
------------------------------
     The first time you run Norton Backup for Windows, your floppy drive
types will be determined automatically.  This automatic configuration is
usually accurate; however, if you see that the drive types have been
determined incorrectly, you can change the settings manually.  Follow these
steps:

    1) If you are not already in the Configure window, click the Configure
       button in the top row of buttons.

    2) Click "Floppy Configuration."

    3) In the dialog box that opens, use the list boxes to select
       the correct floppy drive types for drive A: and B:.
    

If Your Compatibility Test Fails 
--------------------------------
     If your compatibility test fails, the DMA Operation setting will
automatically be set to Most Compatible. Run the compatibility test
again to verify that reliable backups can be made on your system.
Once the DMA Operation setting is set to Most Compatible, you will be 
unable to change this setting manually, as you could in previous
versions. 
     If you change your hardware, it is recommended that you repeat the
compatibility test. Once you are in the Compatibility Test dialog you can
temporarily change the DMA Operation setting to fastest by using the DMA
Operation During Test list box. If the computer passes the test at the
Fastest setting, then the DMA Operation setting will automatically be set
to use the Fastest setting.


Using a 360K Diskette in a 1.2M Drive
-------------------------------------
     Performing backups to 360 K diskettes in a 1.2 MB floppy drive is
not recommended, and will almost surely result in lost data when attempting
to restore.  However, Norton Backup for Windows does support backups to 360 K
diskettes in 1.2 MB floppy drives in order to allow file transfer between
older and newer computers.  The best method to do this is to format the 
diskettes in the 360 K drive, then back up using the "DOS Drive and Path"
setting in the Backup To list box, and the 360 K component size setting in
the Advanced Backup Options dialog box.  Even when this procedure is used,
these diskettes should not be relied upon as the sole backup of a hard disk.

Floppy Drive Contention
-----------------------
     Norton Backup for Windows allows you to switch to other applications
while backing up or restoring data. To ensure that access to the floppy
drives or tape drive is not interrupted during this process, Norton Backup
hides these drives from all other applications.  Programs that display a
list of available drives will not display drives A: and B: during these
background operations.  For the same reason, you should not try to access
your floppy drives directly.  For example, typing FORMAT A: in a DOS window
while using Norton Backup to backup to a floppy drive will produce an "invalid
drive specification" system message. Normal use of the drive will return
once the backup is finished.
     Note that this even applies during tape backups, because the tape 
drives also use the floppy drive controller in your computer.

Floppy Drives Not Supported
---------------------------
     Currently Norton Backup for Windows does not support a 2.88 floppy 
drive or external drives with drive letters above C:. You can back up to 
such drives by selecting them as DOS drive and path.

TAPE DRIVES
===========
          
     Norton Backup supports QIC 117 (interface standard) and QIC
     40 or QIC 80 (format standard) tape drives.

     QIC 02 or other interface tape drives are not supported. Most
     high speed/compression adapters are not currently supported.

Supported Tape Drives
--------------------- 

     Archive 5240 (XT only), 5540, 5580, 3580 (PS/2):
     Some 5240s  have hardware incompatibilities. Norton Backup
     only  supports tape drives that come with serial numbers
     starting with BB or above.  Serial numbers starting with AA
     or AB are not supported.

     Core Light QIC 80:
     Some versions of Core Light's software may not be compatible
     with Norton Backup. You should therefore verify that backups
     made with Core Light's software can be restored with Norton
     Backup. You may want to keep the Core Light software on your
     computer in the event you may need to restore old backups 
     that were not made with Norton Backup.

     Colorado DJ-10 or DJ-20:
     Also known as the "JUMBO 120" (40Mb) or "JUMBO 250" (80Mb).
     The following cards are not supported: the FC-10 Speed Card,
     the TC15, and the TC15M.
        
     Irwin 40sx and 80sx:
     Archive is the manufacturer of these drives. They are identical to the 
     Archive 5540 and Archive 5580.

     Mountain 4000, 8000, 4740(PS/2):
     Summit is the manufacturer of these drives. They are identical to the 
     Summit 4000, 8000, 4740(PS/2) tape drives. These drives can be installed
     as a B-drive or you can use a "third connector" cable.  
          
     Tallgrass FS120 & FS300:
     Summit is the manufacturer of the FS300. The FS300 drive is
     identical to the Summit 8000. Early Tallgrass FS120's were 
     produced by Summit as 4440s. These drives have a circuit board
     that extends past the chassis 1.5 inches.
  
     Recent FS120's are produced by Archive. They are referred to
     by Tallgrass as Irwin Hornet drives, they are actually Archive
     5540s. The circuit board on these drives are exactly the same
     length as the chassis. 

     Tecmar QIC 40:
     Wangtek is the manufacturer for the Tecmar QT40i, see the following
     section.

     Wangtek QIC 3040F5 & 3080F5:
     Make sure you set up these drives correctly.  The jumpers are factory
     set for use as a B: drive. If the tape drive is to be configured as the
     third device, you must change the jumper at the back of the tape drive.

     Wangtek documentation refers to a unique setting for using
     Wangtek drives (3080F5) as a third device on Compaq machines. This will 
     not work with Norton Backup. Use the phantom drive setting instead.


    Tape Drives Not Supported
    -------------------------

    Accutrak 
    Accutrak tape drives, including IBM PS/2 internal tape drives,
    are not compatible at this time.

    CMS Enhancement T2120
    Is not supported at this time.

    DC6000
    DC6000 tape drives are not compatible, they are manufactured by
    Archive, Wangtek, Cipher, Tanberg, Sankyo Seiki.

    Everex 60F and 120F     
    Everex describes the 60F tape drive as QIC 40 compatible. The tapes
    formatted by this machine are QIC40 compatible, however they are not
    QIC 117 interface compatible. Tapes can be interchanged between 
    Everex Software and Norton Backup, but data cannot be exchanged (the
    data format is not compatible.)

    HARDWARE INCOMPATIBILITIES
    ==========================

    Norton Backup is not compatible with the IDE Hard/Floppy disk drive
    controller on some Northgate computers.

    The Zenith Supersport has a DMA bus conflict condition with Norton
    Backup. Norton Backup is not certified to run on this machine.

FILE SELECTION
==============

Manual File Selection
---------------------
     When you select a directory in the tree pane, Norton Backup for
Windows stores the selection by directory name. When you select files
in the tree pane, Norton Backup for Windows stores the selections by
filename. Therefore, selecting all the files in a directory is not the
same as selecting that directory.  For example, if you were to select
your Norton directory and back it up, and at a later date add more 
files to it (such as data files), then those new files would be
included in future backups. On the other hand, if you were to select 
all the files in your Norton directory (as opposed to selecting the
directory itself), any new files added to that directory since the 
last backup will not be backed up.

Setup Files
-----------
     If you are planning on using the same Setup files for both Norton
Backup for DOS and Norton Backup for Windows, use include and exclude 
statements to describe file selections. Manual file selections made
in the Windows product cannot be read by the DOS product.

Directory Tree File Selection
-----------------------------
     You can use the directory tree to quickly select groups of related
directories. When you collapse a branch on the tree the directory displays
a plus sign on the folder. If you select a directory at this point, you
will be selecting all of its subdirectories as well.


ESTIMATED NUMBER OF DISKS FOR A BACKUP
======================================

     More accurate estimates are now made for the number of disks 
needed for a backup, and backup time. These estimates are based on
the compression setting, the data verification setting and your
computer's processor type. 

ADDITIONAL COMMAND LINE OPTIONS
===============================

     Here are some additional command line options not listed in the Norton
Backup documentation:

/m	The minimize switch allows you to start Norton Backup
	as a background operation and display it as an icon.

/p	The password switch allows you to specify your password as 
	part of the command line in the scheduler. This will make it
        possible to run unattended password protected backups.

/b	The backup path switch allows you to specify a different DOS path
	destination for your backup from the DOS path in the setup file.

For more information on these and other command line options, refer
to the Norton Backup for Windows Online Help.

Data Verification vs. Compare Function for Floppy Drives and DOS Path
=====================================================================

     To safeguard your data you should take the time to check that
the data written to your diskettes matches the data on your hard
disk. You can do this through Data Verification while the backup is 
in progress or by using the Compare function after the backup is
complete.

Data Verification
-----------------
     If you back up with the Data Verification option on, Norton
Backup will verify the data by reading it back from the backup 
medium after writing it and comparing it to data in memory.  

Compare Function
----------------
     Compare is a separate function designed to provide maximum
data security.  It checks the data in the backup set against the
source data on the hard disk using the following procedure: 

o    Reads the data on your backup medium exactly as if it were
     going to restore the data to the hard disk.

o    Compares this data to the data found on the hard disk.

o    Verifies that they are identical or displays a message if
     the files do not match.

LIMITATIONS
===========
1.    Characters that can be typed directly from the keyboard can be used
      for passwords.  Do not enter characters in your password by holding 
      the Alt key and typing a three-digit number on the numeric keypad.  

      If you do use these special characters in a password, you will have to
      use the Emergency DOS Restore Diskette or Norton Backup for DOS to
      restore your backup set.


2.    You can back up 2047 directories per drive.  Each directory can 
      contain a maximum of 1638 files, including file names, subdirectories,
      and volume labels.

      If you receive a message that Norton Backup for Windows cannot log
      a drive because it contains either too many directories or too many
      files in a single directory, you can work around this problem as
      follows:
      
      If the drive is a local drive (as opposed to a network drive), use
      the DOS SUBST command to create a new drive letter which maps to 
      that directory you would like to back up.

      If the large drive is a Novell Netware file server, use the MAP 
      command with the ROOT option to map a drive letter to a subdirectory
      on the volume.
