NORTON BACKUP READ.ME - 5/3/90 - EJC
CLEANING YOUR SYSTEM
============================================================
Before installing Norton Backup, you should make sure that
your hard disk is free of any "lost clusters" or "cross-
linked" files. You can use the DOS CHKDSK command or the
Norton Disk Doctor program found in the Norton Utilities 4.5
Advanced Edition.
DMA FAILURE
============================================================
During installation, if the DMA test fails, your machine
might lock up. If this happens, reboot your computer, but
DO NOT run the INSTALL program again. Norton Backup has
already been fully installed when the test fails.
Even though your computer was locked, Norton Backup knows
that the DMA test failed, and will restart the confidence test.
INSTALLING NORTON BACKUP ON AN LCD MONITOR
============================================================
To use the INSTALL program on an LCD screen, use the /LCD
switch on the command line:
A:\>INSTALL /LCD
CONFIDENCE TEST
============================================================
The Confidence test is basically a macro that does a backup
and a restore. If you want to cancel the Confidence Test
after it starts, press ESC twice rapidly.
AUTOMATIC FLOPPY DRIVE CONFIGURATION
============================================================
Compaq machines made before 1988 may have problems with the
automatic floppy drive configuration. After the automatic
floppy drive configuration is complete, you should verify that
the drive types that were selected are accurate for your
computer. If they are not, insert a formatted floppy diskette
and select the Automatic Configuration button. Norton Backup
will then accurately determine the drive type.
CHANGES TO THE MANUAL
============================================================
Page 68, under "Data Verification:
The current text says "Sample Only reads every eighth
track...." It should say "Sample Only reads and compares
every eighth track..."
Page 80, after "Step 3:"
The current text says "To resume recording, press [F7]."
The text should say "To resume recording, simply close the
dialog box you are in."
Page 98, sort options:
The default setting for the display sort is "Name", not "No
Sort" as is indicated. The "No Sort" option as listed in
the manual does not exist.
COMMAND LINE SWITCH /R
============================================================
A new command line switch, /R, has been added. The format
of this switch is:
NBACKUP /R [catalog] filespec [/S]
This switch bypasses the initial file logging done by Norton
Backup, and instead restores the files specified by the
"filespec" parameter from the catalog specified.
The "filespec" parameter allows you to specify the files
that will be restored. The filespec must include a drive
letter and a filename with an extension. Wildcards can be
used (i.e., *.*, *.wk1).
The optional "/S" switch includes all subdirectories in the
search for files that match the filespec.
The optional "catalog" parameter allows you to select a
catalog to restore from. If no catalog is specified, the
catalog from the most recent backup will be used.
An example of this command line would be:
NBACKUP /R CC00420A.FUL C:\ACAD\*.DWG /S
This command line will restore all the drawing files in the
C:\ACAD directory and its subdirectories from the catalog
CC00420A.FUL.
REBUILDING CATALOGS
============================================================
If you have a backup set with missing or damaged disks, you
can use the Rebuild option to rebuild a catalog based on the
remaining set of disks. Depending on your situation, there
are two approaches to take:
1. If you have the original backup catalog and plan to
restore only the files that exist on the remaining backup
disks, you do not need to rebuild the catalog. Simply
select the files from the original catalog and start the
Restore.
2. If you do not know which files are located on which
disks, or if you want to restore all of the remaining data
in the backup set, then you will need to rebuild the backup
catalog.
There is one restriction when rebuilding catalogs. A catalog
can only be rebuilt from consecutive diskettes. In other
words, if you have a backup set of 7 diskettes and diskette
#4 is missing, then you will have to divide the remaining
diskettes into two partial backup sets. The first set would
consist of disks #1-3, while the second would consist of
disks #5-7.
You must restore each partial backup set before proceeding
to rebuild another. In the example above, you must rebuild
and restore the partial catalog created from disks #1-3
before rebuilding the partial catalog created from disks
#5-7. The reason why this must be done is because the two
rebuilt catalogs will have the same name, so one will
overwrite the other.
To rebuild a catalog, follow these steps:
1. Locate one partial backup set
2. Select "Catalog" from the Restore dialog box
3. Select "Rebuild"
4. Choose which drive to rebuild from
5. Insert the diskettes of the backup set as prompted.
6. Choose to overwrite if the catalog already exists
ERROR CODE 3
============================================================
If you receive an "Error 3" message following the configuration
test, this means that the program had an internal error, which
could have been caused by memory or hardware conflicts. You should
reboot your computer from a DOS diskette with no AUTOEXEC.BAT or
CONFIG.SYS file to eliminate any resident programs that may be
conflicting with the Norton Backup, then retry the confidence test.
DOS 4.x DOSSHELL
============================================================
Sometimes, if Norton Backup is run from DOSSHELL, the mouse
will be deactivated. If this happens, create a batch file
that loads the mouse driver, then runs Norton Backup.
DOS VERSIONS
============================================================
It is very important to use a version of DOS that is
specific to your machine. In other words, do not use Compaq
DOS on a Wyse machine, or Wyse DOS on an IBM. Microsoft
licenses MSDOS to different manufacturers, each of which can
make changes to suit their machines. The risk is too great,
because the problems involved with using a DOS version not
specific to your machine may only appear when you attempt to
restore files.
VIDEO PROBLEMS
============================================================
If, after exiting Norton Backup, your screen appears to be
in an incorrect video mode, use the DOS MODE command to clear
any problems. Type "mode co80" for color screens, "mode bw80"
for monochrome. Typing CLS at your DOS prompt should also
clear most problems.
DANGER TO DISK MOTORS
============================================================
Don't run Norton Backup unattended. One reason why Norton
Backup is so fast is because it keeps floppy drives spinning
instead of starting and stopping them every time a disk
needs to be changed. This is not harmful to the drive, but
if there is a long delay between changing disks, the
needless spinning of the drive could potentially damage the
drive motor.
CONCURRENT DOS
============================================================
Norton Backup has not been certified to run under Concurrent
DOS.
MEMORY RESIDENT PROGRAMS
============================================================
Norton Backup optimizes the use of your hardware to improve
backup speed. If you are experiencing strange results while
attempting to do a backup or restore, it is likely that you
have a TSR, disk cache, or expanded memory manager which is
causing an incompatibility. Try removing these programs and
retry Norton Backup. If you still experience problems, then
call our Technical Support Group.
LARGE FILE SIZE DISPLAY
============================================================
If you have selected files that add up to more than 10
megabytes, their size will be represented as "-----" on the
file selection menu.
NBACKUP ENVIRONMENT VARIABLE
============================================================
The Norton Backup will store and search for catalogs in its
own directory, which is the directory where the Backup files
reside. You can tell Backup to use another directory for
holding the catalogs with the NBACKUP environment variable.
For example, if you want the Norton Backup to put the
catalogs in the directory C:\ED\BACKUPS, you should insert
the following line in your AUTOEXEC.BAT file:
SET NBACKUP=C:\ED\BACKUPS
RESTORING FROM A DOS DEVICE
============================================================
When you backup files to a DOS device, you need to enter a
full path (drive letter and directory) as your backup
destination. Norton Backup will then add two subdirectories
to this path. There will be a subdirectory with the name of
the active setup file, and below it, another subdirectory
with the name of the session catalog.
For example, if you backup files from drive C: to F:\BACKUP,
using the default setup file (DEFAULT.SET), Norton Backup
will backup the files to F:\BACKUP\DEFAULT\CF00125A.FUL (For
an explanation of the session catalog name, CF00125A.FUL, see
the manual, page 53).
To restore the backed up files, you must specify the FULL
path, including the directories added by Norton Backup. So,
even though you backed up the files using F:\BACKUP, you
must specify F:\BACKUP\DEFAULT\CF00125A.FUL to restore them.
KEYBOARD DIFFERENCES FOR THE HELP SCREENS
============================================================
When you are on the "Topics" menu on the help screen, you
need to use the TAB and Shift-TAB keys to select topics. The
highlight bar may appear to do strange things if you use the
arrow keys. The arrow keys scroll the entire menu, and the
highlight bar will remain on the selected topic as you
scroll the screen. If you scroll the selected item off of
the screen, the highlight bar will fall onto the next item.
DOS BUFFERS
============================================================
Because the number of BUFFERS specified in the CONFIG.SYS
file is so important to the success of the Norton Backup,
the install program will now check the BUFFERS statement and
ask if you want it to be changed.
DOS INDEX
============================================================
A DOS Index of less than 100% during backup indicates that
there are too few DOS buffers. If you find that the DOS Index
is consistently falling below 100%, try increasing the BUFFERS
value in your CONFIG.SYS file to 40 for an AT class computer,
and 20 for an XT class computer.
REGISTRATION WINDOW
============================================================
The Registration window is for personalizing your copy of
Norton Backup. This does not copy protect Norton Backup or
affect the program in any other way.
SETUP FILES
============================================================
The maximum number of setup files (.SET files) that Backup
can select from is 50. You can have as many .SET files as
your disk will hold, but Norton Backup will only use the 50
oldest (by date) files.
NORTON BACKUP DISTRIBUTION DISKS
============================================================
One 3 1/2" disk and two 5 1/4" disks are included with the
Norton Backup. The 5 1/4" disks contain the following
files:
Disk 1: INSTALL.EXE Disk 2: NB2.DAT
INSTALL.DAT INSTALL.HLP
INSTALL.OVL
INSTALL.HLP
NB1.DAT
READ.ME
The .DAT files contain all of the Norton Backup program
files in compressed format. The INSTALL.EXE program will
automatically decompress the files.
After Norton Backup has been installed, you should have the
following files:
NBACKUP.CFG Holds the configuration settings
NBACKUP.EXE Norton Backup loader
NBACKUP.HLP The help section of Norton Backup
NBACKUP.OVL Main Norton Backup program module
NBCONFIG.HLP Configuration help section
NBCONFIG.OVL Configuration program module
NBINFO.OVL System analysis module
NB_FLP_B.OVL Backup program module
NB_FLP_R.OVL Restore program module
After running a backup or a restore, there may be two files
in your Norton Backup directory. These files, called
NBACKUP.TMP and RESTORE.TMP, contain information about the
configuration used for the most recent backup and restore.
This information can be useful if you need to contact
Technical Support.
