   1.  Installing your Backup Software
-------------------------------------------------------------------------------------

A.  CONFIG.SYS Changes
    ------------------
    When you install your backup software, one or more device
    statements will be added to your CONFIG.SYS file in the
    following format:
    'DEVICE=<install path> <driver name>'.
    
B.  Memory Requirements
    -------------------
    Your backup software requires a minimum of 6MB free
    memory to function. At least 12MB free memory
    is recommended for optimal performance. It is not
    recommended that you mix memory chips
    (SIMMs) in your system configuration. Use chips
    of the same type.
    
C.  Installing to a Network
    -----------------------
    Avoid installing this version of your backup software
    on a drive that is not available at boot up, such as a
    LANServer or NetWare mapped drive.
    
D.  Using OS/2 Version 2.1
    ----------------------
    If you are using OS/2 version 2.1, upgrade with the
    OS/2 "Service Pak" before using your backup software. If
    you do not upgrade your OS/2 system, you will not be able to
    complete the install process, the Installer will crash,
    and your system will require rebooting.
    
E.  Creating Emergency Restore Diskettes
    ------------------------------------
    You should create Emergency Restore diskettes in case you
    have to recover from a system crash or other emergency
    situations. To create the diskettes, the Installer uses
    OS/2's Rexx utilities. If the Rexx utilities are not on
    your system, refer to the advanced installation instructions
    in your OS/2 installation guide.
    
F.  Uninstalling and Reinstalling
    -----------------------------
    If you accidentally delete any of your backup software desktop
    objects, from an OS/2 prompt, go to the directory where you
    installed the backup software and type 'PDESK CREATE'. The deleted desktop
    objects will be re-created in the backup folder.
    
    If you have accidentally deleted one or more of your backup
    software files, you should uninstall by dragging the backup
    folder to the shredder.  After files are uninstalled, shut
    down and reboot OS/2, then reinstall your backup software
    to the same directory. Your catalog database will remain
    intact as long as you reinstall to the same directory.
    
    If you have trouble with the above procedure, you can use
    the UNINST.CMD provided on your installation diskette.
    
    NOTE:If you create or move a backup definition object onto
    the desktop, or to a folder other than the Backup folder
    or the More... folder, you must manually delete the object
    before uninstalling the product. If you uninstall the product
    before deleting these backup definitions, you must complete
    the uninstall by manually deleting the objects and running
    the UNINST.CMD script.
    

   2.  Device Configuration
-------------------------------------------------------------------------------------
A.  Using a High-Speed Controller Card
    ----------------------------------
    A 3020 tape drive can be connected to a 1MB or 2MB
    high-speed controller card. Performance is optimal
    with a 2MB card. A 3020 tape drive functions as a
    3010 drive when connected to a 500KB controller
    card. The 3020 tape drive cannot read a 3020 formatted
    tape if connected to a 500KB controller card. In
    this case, re-format your tapes as 3010 to use in the
    3020 drive.
    
    A 3010 tape drive can be connected to a 1MB or 2MB
    high-speed controller card, but functions at a maximum
    rate of 1MB.
    
    A QIC-80 tape drive can be connected to a 1MB or 2MB
    high-speed controller card, but functions at a maximum
    rate of 1MB.
    
B.  Device Driver and Other Conflicts
    ---------------------------------
    When you connect your tape drive to a secondary high-speed
    controller in a system with a 82078 chip, DMA channel 2
    may not be sharable between the floppy disk controller and
    the high-speed controller. Change the jumper setting on the
    high-speed controller to another DMA channel, otherwise
    this conflict can cause backups to fail.
    
    If you attempt to use your backup software while a screen
    saver is active and you get DMA errors or other errors,
    manually disable the screen saver before running a backup.
    
C.  CITOBASE Errors and Other Conflicts
    ---------------------------------------
    If you receive the error message "The system cannot find
    file CITOBASE", try the following fixes before calling:
      1. Reinstall the backup product.
      2. Open the config.sys file and confirm that there is a ".;" in
         the LIBPATH statement.
    If you receive the error message "Cannot start c:\qbos2\pdesk.exe",
    open the directory in which you installed the backup software.
    Type 'pdesk start_here'.
    
    NOTE:Do not, at any time, remove the ".;" from the LIBPATH
    in the config.sys file.
    
D.  Using Laptops or Notebooks
    --------------------------
    Some laptops use power management features. This may create
    a conflict during a backup, a restore, or a tape formatting
    operation. To avoid this conflict, while using your backup
    software, turn all power management features OFF and plug
    your laptop into an outlet instead of using the battery.
    
E.  Using Parallel Port Tape Drives
    -------------------------------
    Connect a parallel port tape drive 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 cable,
    if possible, or disconnect the tape drive while printing.
    
    If your parallel port tape drive will not configure, you may
    have an interrupt request (IRQ) conflict between the tape
    drive and a sound card.  SoundBlaster cards and compatibles
    use a default IRQ of 7, which is also used by the printer
    port (LPT1). A printer does not require a hardware interrupt
    and operates normally even if an interrupt conflict exists.
    Other cards and devices can also conflict with the parallel
    port, such as a scanner card, a network card, or a bus mouse.
    
    To resolve this conflict, change either the IRQ of the
    conflicting card, or the IRQ of the parallel port. Check
    your system or card documentation to verify that this change
    can be made.
    
    NOTE: Some games may not work correctly if the sound
           card's IRQ is changed.


   3.  Using Compressed Drives
-------------------------------------------------------------------------------------
If you are using compression software such as Stacker, do not
back up the compressed file (for example, stacvol.*). Back up
the logical drive instead.


   4.  Naming and Renaming Tapes
-------------------------------------------------------------------------------------
When prompted to enter a tape name, always enter a unique name.
Otherwise, if tapes of the same name are used for a multi-tape
backup, the backup software will not be able to distinguish
between the two tapes.  You may want to choose tape names
such as "Finance #1" and "Finance #2" to identify tapes in
a series.


   5.  Backing Up Network Files
-------------------------------------------------------------------------------------
A.  NetWare Requester for OS/2
    --------------------------
    If you are using a version of NetWare Client for OS/2 prior
    to 2.11, your backup software will not overwrite read-only
    files during a restore. You can either upgrade the NetWare
    Client or use the 'attrib -r' command to remove the read-only
    attribute from these files.
    
    NetWare bindery files are not backed up with this version of
    backup software.
    
B.  LANServer Files
    ---------------
    LANServer access control lists are not backed up with this
    version of backup software.


   6.  Scheduling Backups
-------------------------------------------------------------------------------------
When you schedule a backup, your system must be ON for the
Scheduler to launch the backup automatically. While your
computer is OFF, backups which would have been launched
will be skipped, and you will not be notified about missed
events. When your computer is running again, the Scheduler
will resume with the next scheduled event.


   7.  Files that are Not Backed Up
-------------------------------------------------------------------------------------
Files that are busy or locked when your backup software
attempts access will be skipped and not backed up. Certain
files are not logged or backed up to avoid potential
conflicts if restored:

    File Name                    File Type
    ---------                    ---------
    EA_DATA.SF                   OS/2 extended attributes file

      NOTE:Your backup software does not back up this file,
            but does back up extended attributes.

    SWAPPER.DAT                  OS/2 swap file

    QBOS2.ACF, .CFG, .APF, .CFX  Backup software configuration files

      NOTE:Your backup software only skips the QBOS2.* files
            if they are in the run directory.

    *.RPT                        Report files

      NOTE:Your backup software only skips the *.RPT files
            if they are in the run directory.

    A*.TMP                       Temporary files created for storage
                                 in a temporary or current directory

      NOTE:Your backup software skips the A*.TMP files that are
            in the working directory (i.e. either the TEMP or
            current directory).

NOTE:If you are attempting to delete any of the QBOS2.* files, you
must first shut down the backup server in the task list in order
to access and delete these files.


   8.  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.


   9.  Configuration Corruption
-------------------------------------------------------------------------------------
If you experience a power interruption, system failure,
or system hang while using your backup software, certain
files may become corrupted. If the configuration file is
corrupted, you may not be able to start a backup or other
processes. Delete the file QBOS2.CFG, then reconfigure your
drive from the Tape Device object Settings page. If you
continue to experience problems, the catalog database
may also be corrupted. Delete the file QBOS2.ACF and the
file will be re-created with your next backup. Tape
information in the corrupted file will be lost, but you
can restore data from those tapes with the Select Files
from Tape option.


  10.  Tape Tools:Erase Tape
-------------------------------------------------------------------------------------
The Erase Tape tool does not prompt for a tape name. If you
want to rename your tape, select Rename Tape from the Tape
Device object Tape Tools menu.


  11.  Menu Descriptions
-------------------------------------------------------------------------------------
Throughout the User Guide the menus are described according to
Version 2.1. There may be some slight variations from Warp
versions of OS/2.


  12.  Using Restore as a Data Transfer Tool
-------------------------------------------------------------------------------------
Restore and Emergency Restore are not designed as a data
transfer tool. System specific files, when transferred to
another system, will cause the system to be unuseable. The
Restore and Emergency Restore processes are intended solely
to restore the originally backed up system in the case of
catastrophic loss.


  13.  HPFS and FAT Partition Conflict
-------------------------------------------------------------------------------------
If you are attempting to restore from an HPFS partition to a FAT
partition, you must conform to the FAT partition format. Long
filenames cannot be restored to FAT partitions therefore you must
use the FAT partition format.


  14.  Compatibility with Other Products and Hardware
-------------------------------------------------------------------------------------
A.  Using an Adaptec 1542B SCSI card
    --------------------------------
    If you are using an Adaptec 1542B SCSI card with both a hard
    drive and a SCSI or QIC tape device connected and are
    experiencing DMA errors, add the following to your driver
    line in the config.sys file to prevent further BUS errors:
    /V /A:0 /BON /A:0 /BOFF:8
 
B.  Using Windows 95
    ----------------
    Your backup software does not back up Windows 95 partitions.
 
    Windows 95 applet tapes (these tapes came with the Windows
    95 product) cannot be restored using this backup product.
 
C.  Using Dualstor
    --------------
    Dualstor uses a proprietary format for 'compressed QIC-80
    wide' backup sets. Due to this proprietary format this product
    is unable to restore the files backed up by Dualstor. Use
    Dualstor to restore these backup sets.
 
    NOTE:Non-compressed, non-wide backup sets will be restored
    by this product without error.
 

  15.  Backing up the Windows Swap File
-------------------------------------------------------------------------------------
It is not recommended to back up the Windows swap file (386SPART.PAR).
If you do back up the swap file, upon restarting Windows, you will
receive the error 'Corrupt swap file.' Follow the directions
in the window to recover the information.
 

  16.  Using Sytron Products
-------------------------------------------------------------------------------------
A.  Using Sytos Premium
    -------------------
    NOTE:Do not delete your Sytos product.

    Backups created using Sytos Premium, version 2.0 or higher, can be
    restored using the Restore Assistant. However, Sytos backups cannot
    be restored in a parallel port tape drive. Do not use
    Sytos backup tapes with the Emergency Restore process in
    this product.

B.  Using Sytron Drivers
    --------------------
    If you are using a Sytron product, you may experience device
    driver conflicts with this product. If a device driver conflict
    occurs, rem or comment out all Sytron drivers in the config.sys file.

C.  Appending to Sytos Backups
    --------------------------
    Backups created using this product cannot be appended to a
    Sytos backup because a proprietary data formatting method is used.
    If you attempt to append, you will receive a message that the tape
    is full. Use either a different tape or overwrite the
    Sytos tape.

D.  Spanning Using Sytos Tapes
    --------------------------
    Backups created by Sytos products such as multiple backup sets and
    compressed or uncompressed backups on a single tape are restorable
    with this product. It also successfully completes selective, full,
    or multiple volume restores from a single tape.

    All options normally available with other tapes are also available
    to use with Sytos. Sytos tapes can restore to an original location
    or an alternate drive or folder. During the restore, you can choose
    to overwrite older only, never overwrite, or always overwrite files.

    Certain backup sets created with Sytos that span more than one tape may
    not restore. If you experience difficulty restoring spanned Sytos tapes,
    revert to the Sytos product for your restore.


  17.  Using CMS QIC-40 and QIC-80 Drives
-------------------------------------------------------------------------------------
Firmware versions 87 and higher are supported by this backup
software. Our software will not function optimally if you are
using a CMS QIC-40 or QIC-80 drive with firmware
(version 86 or older). Spanning in particular will not function
optimally.


  18.  Using an APS MobilStor Drive with an EPFA Chip
-------------------------------------------------------------------------------------
If you are using an APS MobilStor drive with an EPFA chip, the backup
product will not detect the drive. This product does not support the
EPFA chip. Please contact the drive company for an upgrade.
