   1.  Verify Your First Backup
-------------------------------------------------------------------------------------
When you make your first backup with Conner Backup Exec, it
is highly recommended that you use the Verify After Backup
option. During the Verify phase, Conner Backup Exec compares
each file on the tape with the original on your hard drive to
ensure that they are identical. While verifying will increase
the time of the backup, it will confirm that your computer
system, tape drive, and Conner Backup Exec are working
together correctly.

If compare fails, run a hard disk utility program to determine
whether the hard drive is free of errors and try the backup again.


   2.  Before You Run Your First Scheduled Backup
-------------------------------------------------------------------------------------
Before you run your first scheduled backup, you should run
a short backup with Verify After Backup selected (see above).
When the window advising you to not use your floppy drives
during backup appears, select "Disable This Message." This
will allow your scheduled backup to proceed uninterrupted.


   3.  Tape Format Incompatibilities
-------------------------------------------------------------------------------------
Conner Backup Exec cannot format AccuTrak tapes.


   4.  Installing Conner Backup Exec After Other Backup Programs
-------------------------------------------------------------------------------------
You may experience difficulty running Conner Backup Exec
if some device files from other backup programs are
found in your SYSTEM.INI file. If you can't start
Conner Backup Exec, try commenting the following devices out
of your SYSTEM.INI file:

    CMSWTAPE.386
    CMSDTAPE.386
    CPBVXD.386
    FASTBACK.386
    IRW286.DRV
    NOVABKP.386
    VIRWT.386
    VITD.386
    DCVXD.386

To do this:

  1. Open the SYSTEM.INI file using a text editor.
  2. Search for the device name(s), e.g., DEVICE=CPBVXD.386
  3. Type a semicolon (;) at the beginning of the line.


   5.  Installing DOS 6.x After Conner Backup Exec for Windows
-------------------------------------------------------------------------------------
DOS 6.x installs an older version of the VFINTD.386 into the
DOS directory and then modifies the SYSTEM.INI
(DEVICE=C:\DOS\VFINTD.386). If you install MS-DOS 6.x after
Conner Backup Exec 5.0a, the next time you launch Conner Backup Exec you
will be sent a warning dialog. This dialog notifies you that
the VFINTD.386 is the incorrect version. If you click OK in
this dialog Conner Backup Exec will save the existing SYSTEM.INI as
SYSTEM.QBW and make the necessary change to the "Device=" line
in the SYSTEM.INI. You can also make the changes manually by
performing the following steps:

  1. Open the SYSTEM.INI file using a text editor.
  2. Search for the VFINTD line (DEVICE=C:\DOS\VFINTD.386).
  3. Change the line to: DEVICE = [qbwin install path]\VFINTD.386.


   6.  Setup Disk Space Estimates
-------------------------------------------------------------------------------------
To insure that the user always has enough disk space to
install Conner Backup Exec, the Setup program displays the
maximum amount of space that will be required for installation.
This estimate is affected by the actual options selected
for install and also includes some space that is necessary
in order to run the setup program.


   7.  Compressed Drives
-------------------------------------------------------------------------------------
If you are using compression software such as Stacker or
DoubleSpace, do not back up the compressed file (for example,
stacvol.* or the dblspace files), back up the logical drive
instead. Because these compressed files are typically very
large, attempting to restore may cause problems if you do not
have enough disk space to restore the compressed file.


   8.  Laptop/Notebook Video Conflicts
-------------------------------------------------------------------------------------
Some laptop and notebook computers may have video conflicts
that cause the tape drive to move the tape back and forth
excessively  ("shoe-shining").

If you experience this, try minimizing the Conner Backup Exec icon
and making the Program Manager window active and moving it over
the top of the icon while the program is writing to or reading
from the tape. The Conner Backup Exec window will activate itself
when the backup or restore is finished, and this action should
speed up your session.


   9.  Power Management Conflicts
-------------------------------------------------------------------------------------
Some Desktop computer systems and laptops have power
management systems that take a "snapshot" of RAM and
store it on the hard drive when they power down. This
may create a conflict if it occurs during a backup or
restore or a tape formatting operation.

When using Conner Backup Exec, it is recommended that you turn
OFF all power management features. If you're using
a laptop, avoid running power management features
by using an outlet rather than batteries.


  10.  Hardware Compression Not Supported
-------------------------------------------------------------------------------------
Conner Backup Exec for Windows, Version 5.0a, does not support
the hardware compression function found on some high-speed
controller cards.


  11.  Installing With Third-Party Windows Shells
-------------------------------------------------------------------------------------
If you use a third-party Windows shell program such as PCTools
or Norton Desktop for Windows, Conner Backup Exec may
not install correctly. If you experience difficulty installing
Conner Backup Exec under a shell, temporarily change your Windows shell
to the Program Manager before starting the setup program. To
change to the Program Manager, open your SYSTEM.INI file,
type a semicolon (;) in front of your current SHELL command in
the [boot] section, then type SHELL=PROGMAN.EXE on the following
line. For this change to take effect, you must restart Windows.
Remove these changes after installation to restore your
previous configuration.


  12.  Parallel Port Drive Configuration
-------------------------------------------------------------------------------------
If your parallel port tape drive does not automatically
configure, first ensure that the power to the drive is on. If
it is, turn it off, then on, and try configuring it again. See
below for more suggestions.


  13.  Maximum Parallel Port Cable Length
-------------------------------------------------------------------------------------
Your parallel port tape drive should be connected directly to
your system's parallel port. If you use the pass-through
connector on the drive to connect a second device such as a
printer, the maximum cable length for both devices is
approximately 10 feet (3 meters).

If you have difficulty using your tape drive when a second
device is connected to the pass-through connector, disconnect
the second device and its cable while using the tape drive.

If you experience data loss when using a printer connected to
the pass-through connector, shorten the printer's cable if
possible or disconnect the tape drive while printing.


  14.  IRQ Conflicts
-------------------------------------------------------------------------------------
You may experience a conflict in IRQ selection if you are
configuring a parallel port tape drive on a system that
includes a sound card. SoundBlaster cards and compatibles use a
default IRQ of 7, which is also used by a printer port (LPT1).
If this conflict occurs, you can:

    *  Change your sound card's IRQ if possible. Some cards do
       not allow this change and some games may not work
       correctly.

    *  Check your system documentation to see if your parallel port
       can be configured to use a different interrupt.

Devices that may conflict with printer port interrupt:

       Sound Cards
       Scanner Cards
       Network Cards
       Bus Mice
       Other printer ports
       Other devices

If you are running Windows 3.1, IRQ usage can be determined by
using the Microsoft Diagnostics Program. Exit Windows and type
MSD at the DOS prompt. Note that MSD cannot always diagnose
printer port IRQ conflicts. Printing does not require a hardware
interrupt and will function normally even if an interrupt
conflict exists.

If you are running Windows 95:

1.  Double-click the My Computer icon.
2.  Double-click the Control Panel icon.
3.  Double-click the System icon.
4.  Click the Device Manager tab in the System Properties window.
    The device Manager tab appears.
5.  Select the hardware that you want to change settings for,
    then click Properties.
    The Properties window appears.
6.  Click the Resources tab in the Properties window.
7.  De-select Use Automatic Settings.
8.  To change your Input/Output Range, select a setting from the
    Setting based on box.
9.  To change your Interrupt Request or Direct Memory Access
    settings, highlight the item and click Change Setting. Make
    any changes and click OK.
10. Close the System control panel.
11. Shut down your computer.
12. If necessary, make any changes to your high-speed controller
    card's settings and install it in your system. See your
    hardware manual for instructions.
13. Restart your computer and Windows 95.

Symptoms of an IRQ conflict include Conner Backup Exec not
finding the tape controller and network problems when
backing up to tape.


  15.  Potential Conflict with Screen Savers
-------------------------------------------------------------------------------------
Some screen savers will not activate while a
backup, compare, or restore is running and
Conner Backup Exec is minimized. For optimum
performance, we recommend that you disable your
screen saver while using Conner Backup Exec.
However, if you wish to use your screen saver,
you must first make sure Conner Backup Exec
is not minimized.


  16.  Encrypted Backup Sets
-------------------------------------------------------------------------------------
Conner Backup Exec cannot restore backup sets encrypted by
other backup programs. You must use the original software to
restore them.


  17.  Files Not Backed Up by Conner Backup Exec
-------------------------------------------------------------------------------------
Conner Backup Exec does not log or back up a number of files
to avoid potential system conflicts if they are restored.

  Compressed Volume files:

     DBLSPACE.0??
     DRVSPACE.0??
     STACVOL.*

  Windows swap files:

     386SPART.PAR (Windows 3.1 only)
     WIN386.SWP


  18.  Formatting Tapes on 386 Machines
-------------------------------------------------------------------------------------
If you encounter difficulties formatting tapes on a slower 386
machine or receive a message stating "The tape controller is not
responding correctly," make sure your turbo switch is on.


  19.  Changes to SYSTEM.INI and WIN.INI
-------------------------------------------------------------------------------------
The following lines are added during installation:

WIN.INI [Extensions]
    set=[qbwin install path]\qbwin.exe^set

SYSTEM.INI [386enh]
    device=[qbwin install path]\vfintd.386

WIN.INI [Windows]
    load=[qbwin install path]\qbwsched.exe


  20.  Using Removable Media Drives
-------------------------------------------------------------------------------------
For your backup software to recognize and use a removable media
drive such as a Bernoulli drive, the drive must be locked.


  21.  Restoring Files with NetWare Delete Inhibit or Rename
       Inhibit Attributes
-------------------------------------------------------------------------------------
During a Restore, you cannot overwrite files which have
the NetWare Delete Inhibit (D) or Rename Inhibit (R)
attribute set. To restore these files, you must first manually
remove the Delete Inhibit or Rename Inhibit attribute.


  22.  3020 Drive Requirements
-------------------------------------------------------------------------------------
To achieve optimal performance with a 3020 drive, a 1Mbit
controller or higher (2Mbit) is required.


  23.  Controller Conflicts
-------------------------------------------------------------------------------------
The Promise 2300 EIDE VLB controller must run in fast
mode (/f parameter) in order to work with floppy tape drives.


  24.  Possible Video Conflicts
-------------------------------------------------------------------------------------
Problems have occurred with various video drivers and the video
compatibility test in Windows. If your software hangs during the
Compatibility Test, try to get an update of the video driver
from the card manufacturer. Conflicts have occurred with Diamond
Stealth 64, ATI Ultra Mach 32/64 cards, and other cards using
the Cirrus Logic chip set.


  25.  EZ-Drive Disk Manager
-------------------------------------------------------------------------------------
The following information applies to systems
with high-capacity hard drives using the Micro
House EZ-Drive disk manager:

Before starting Conner Backup Exec for Windows, make
sure that the Micro House EZ-Drive Virtual Driver
is installed by running the SETUP.EXE program on
the EZ-Drive installation diskette. This setup program
adds the line "device=MH32BIT.SYS" to the [386Enh]
section of your SYSTEM.INI file.

Then follow the steps below:

1.  Click the Windows Control Panel's "Enhanced" icon.
2.  Select the Virtual Memory... button.
3.  Select the Change>> button.

Ensure the "Use 32-Bit Disk Access" check box is checked.
This check box must remain checked in order to use
Conner Backup Exec for Windows.


If you continue to encounter problems using Conner Backup Exec
for Windows, and if you are using a QIC floppy tape or
parallel port tape drive, follow the steps below:

1.  Open Conner Backup Exec.
2.  Select the Configure button.
3.  Select the Settings button.
    The Settings dialog appears.
4.  Select the Most Compatible setting in
    the DMA Operation combo box.

This results in lower performance, but may be necessary on some
systems for proper operation.
