Welcome to the Demo Version of the IBM DualStor Backup Program
for DOS Version 2.0!
All operations of the DualStor for DOS program are enabled with this
Demo version EXCEPT the Restore operation. You can Select the
Restore operation but after you enter the Restore parameters, you
will receive a message indicating the Restore operation is disabled.
To install this Demo version, insert the DualStor for DOS diskette
in a 3.5" floppy drive and enter 'x:setup' where x=your 3.5" floppy
drive designator (for example, a:setup).
After DualStor for DOS is installed, enter 'dualstr' from the 'x:\DUALSTOR\'
command prompt to start the DualStor application.
We hope you like DualStor! If you would like to purchase DualStor for
DOS you can call Options by IBM at 1-800-426-7299 (US Only) or IBM

1 - DUALSTOR EXECUTION
----------------------------------------------------------------------
----------
*Incremental vs. Differential Backup Methods*
The only difference between Incremental and Differential backups
is the Incremental method will reset the archive bits and the
Differential does not reset the archive bits. Both methods
will back up the same files from your hard disk based on the
archive bit. Checked files that have the archive bit set on
will be backed up.
----------
*Printing in DualStor*
At this time, DualStor can print files to disk, but not to a printer.
To work around this limitation, select Print from the File menu,
select OK, and name the file you want to save on disk. At a DOS
prompt, type PRINT FILENAME. For more information on printing from the
DOS prompt, see your DOS documentation.
----------
*AutoTape Command Prompt*
When entering a command in the AutoTape command box, be sure to use
the extension of the file being used so that the operation will work
properly. For example:
DUALSTR.EXE FULL-CDE.TPF
----------
*~BEX Files*
Files that begin with ~BEX are temporary files used by DualStor. If
you see one of these files when DualStor is not running, you can
delete them. ~BEX files will be found either in your TEMP directory or
your DualStor directory.
----------
*Ignoring Drives in DualStor*
You can tell DualStor to ignore specified drives, if you have non-
existent drives that are creating error messages or speed problems when
you run DualStor. For example, if you have a computer with a single
floppy drive (drive A:), you can have DualStor ignore your non-existent
drive. You may also want to use this setting to tell DualStor to ignore
both A: and B: drives so that they do not appear in your DualStor Drives
window. The default Drives selection would then always be your C:
drive.
To do this, add the following command to the DUALSTR section of your
DUALSTR.INI file (located in your DUALSTOR directory).
IRSKIPDISK=ab
You can list as many drive letters as you want, putting no spaces
between them, for example, IRSKIPDISK=abcd (to ignore your A:, B:,
C:, and D: drives).
You can achieve the same thing by putting a SET statement in your
AUTOEXEC.BAT file. The syntax is:
SET IRSKIPDISK=abcd
----------------------------------------------------------------------
2 - DUALSTOR AND DOS
----------------------------------------------------------------------
*DualStor in the Windows and OS/2 Presentation Manager Environments*
Do not attempt to run DualStor from a DOS window or full screen in
either Windows or OS/2. If you do so, the program will either halt or
run very slowly. You can purchase a DualStor product that is designed
specifically for your operating environment. Consult your dealer for
information about DualStor for Windows or DualStor for OS/2.
----------
*DOS Memory Management and DualStor*
To get the best performance with DualStor you should use Upper
Memory Blocks (UMBs). Refer to the chapter, 'Optimizing Your
System' in your DOS documentation for information on using
UMBs.
If you have UMB enabled and you are experiencing memory
management problems with DualStor for DOS try entering the
following command at the DOS prompt before starting DualStor.
SET NOUMBSUPP=1
You could add the following statement to your AUTOEXEC.BAT instead.
SET NOUMBSUPP=1
----------
*Disk Caching and DualStor*
You will also find that DualStor will run more quickly and smoothly
when there is a disk caching program installed on your system. Disk
caching improves performance by storing parts of the program in the
computer's memory rather than only on disk.
Most users now load a disk cache when their computer starts up.
A disk cache program may be included with your DOS product and
there are a number of third party programs as well. If you have more
than 640K memory available, we recommend that you use part of this
memory for a disk cache.
Note: DualStor does not require the use of a disk cache. However, if
you do not use disk caching, you may notice that DualStor takes longer
to load than expected.
----------
*Setting the TZ Environment Variable
The TZ environment variable is not compatible with either DualStor for DOS
or Windows. Having the line 'SET TZ=' in your AUTOEXEC.BAT file will cause
the time based functions in DualStor to be inaccurate (ex. elapsed time will
be 00:00:00 and the transfer rate will be incorrect). It is recommended that
the TZ set variable be removed from AUTOEXEC.BAT before performing a
backup or restore.
If you did create backup sets with TZ enabled you will need to 'SET TZ='
again before you can recover your data with DualStor.
----------------------------------------------------------------------
3 - DUALSTOR JOB (PARAMETER) FILES
----------------------------------------------------------------------
*Using Parameter Files from PS2Tape and PMTape*
If you have parameter files created for PS2Tape or PMTape, they will
work with DualStor by copying them into the DualStor directory.
Parameter files are now called job files and can be created more
easily using options in the DualStor Jobs menu. Be sure that your
existing parameter files have names different from the five job files
created during DualStor installation (FULL.TPF, DIFFR.TPF, INCR.TPF,
REST.TPF, and TAPEINFO.TPF), so you don't overwrite any of them.
Because of enhancements to job file capabilities, some of the syntax
for job file commands has changed. Your existing parameter files will
still run, but first you should review Appendix B in your User Manual
for detailed information on the new job file command syntax.
----------
*Logging a DualStor Operation*
All DualStor operations, including operations launched from job files,
are logged in a DualStor Session Log. If you want to create a log file
in a specific location with a specific name, open the job file using a
text editor and add the following command:
/l log_name
The /l command is a job file "option" available in backup and restore
modes. The log file will be saved in your DualStor directory or you
can specify a full path. For example:
/l c:\bulogs\backup.log
The log file will list files that were included and/or excluded from
the operation depending on the logging settings specified in DualStor.
DualStor creates the log file after you exit the program. See Appendix
B in the DualStor User Manual for more information on job file
editing.
----------
*Mode Variables*
There is only one mode variable allowed in each Job file (i.e. *.tpf)
Mode variables are !backup, !restore, !init, !util, and !shortcuts.
----------
*Encryption and Password Options*
The Encryption and Password options are not available for use with
Job files. Therefore, if you check the Encryption option in your
Settings pull-down, Backup defaults window it will not be enabled
(it will be grayed out) when you save a Job file.
----------
*Date Specification*
When using the '/d' option in a DualStor Job file you must have a
space on both sides of the date_spec value.
----------------------------------------------------------------------
4 - DUALSTOR AND NETWORKS
----------------------------------------------------------------------
*Novell Volume Restrictions*
Novell volume restrictions will only be backed up if you use QIC tapes
with the DualStor file system or you use Servo (AccuTrak) tapes.
Volume restrictions are not backed up using QIC tapes with the
QIC-Compatible file system (QIC-80 and QIC-113). See your DualStor
User's Guide for more information on file systems.
----------------------------------------------------------------------
5 - COMPATIBILITY WITH OTHER SOFTWARE AND HARDWARE
----------------------------------------------------------------------
*Intel Premiere II PCI Motherboard*
If you have a Pentium system with the Intel P90 motherboard
(Premiere II PCI, codename Plato) and you are experiencing
slow transfer rates, 'DMA Overruns', or excessive shoe-shining
(tape spins backward and forward continuously) when performing
DualStor backup operations, you should first call the Intel Bulletin
Board at 916-356-3600 and search on 'BIOS' for information that
could resolve these problems.
----------
*Removing Other Software Device Drivers*
If you were using another tape backup software product previous
to DualStor for DOS you should remove any of its device driver
entries from your CONFIG.SYS before trying to execute DualStor
for DOS.
----------
*DMA Channel 2*
Prior to executing DualStor for DOS make sure you have no
entries in your CONFIG.SYS that are using DMA Channel 2.
----------
*National Semiconductor Floppy Controller DP8473*
If the DualStor for DOS software detects this floppy
controller on your system, the DualStor software will
use a maximum transfer rate of 500Kbps (vs. 1Mbps).
This is due to this floppy controller not containing a
FIFO.
----------
*Compatibility with QICstream*
QICstream backup software cannot read DualStor backup sets that are
compressed.
----------
*Compatibility with Colorado Memory System Backup Software*
CMS's Colorado Backup software cannot read DualStor backup sets that
are compressed.
----------
*4100MC and IBM Model 9577*
The 4100MC controller card in an IBM Model 9577 will cause DualStor
to work improperly. To avoid this problem, connect your tape drive to
your computer's floppy controller rather than the 4100MC card. See
your tape drive's installation guide for more information.
----------
*SCSI Hard Drives and the Adaptec 1540 Controller*
If you are using:
* a tape drive with a floppy controller AND
* a SCSI hard drive with an Adaptec 1540 controller,
you must set the IROPT environment variable. To set IROPT, enter the
following command at the DOS prompt before you start DualStor:
SET IROPT=Y
Note that the Y must be in upper case. You may include this command as
part of your AUTOEXEC.BAT file.
----------
*SpeedSTAR VGA Monitor Problem*
If you are using DualStor with a SpeedSTAR VGA monitor card that has a
DBIOS version 4.23, you cannot run in 43/50 line mode and graphics
mode simultaneously. Select Font from the View menu, check the
graphics mode check box, and leave 43/50 line mode unchecked.
----------------------------------------------------------------------
6 - DUALSTOR 2.0 CHANGES FROM VERSIONS 1.x
----------------------------------------------------------------------
*Default Backup Set Names*
If you mark specific directories and/or files for backup as opposed to
marking an entire hard drive, the default backup set name will be
"Partial-X" where 'X' is the drive designator of the hard drive on
which the directories and/or files marked for backup reside. DualStor
versions 1.x used a default backup set name of "Full-X".
----------
*Column Headers*
Column headers were added to the tops of the file windows. These
column headers identify the column by name (ex. "Name", "Date",
etc.). The columns can be sized by dragging the separator line
between each column (the separator line to the left of "Name"
is not enabled). Click the left mouse button on any column to sort
the entire list by that column.
----------------------------------------------------------------------
7 - MISCELLANEOUS
----------------------------------------------------------------------
*Verify after Backup*
It is a good practice to check the 'Verify after Backup' option on when
selecting your Backup Parameters. This will cause DualStor to
perform a byte-by-byte comparison between the data backed up on
the tape and the data on the hard drive increasing your confidence
in the backup. It may, however, double the time of your backup.
If you want to set this option on permanently for all of your backups,
simply select the Settings pull-down, Backup..., and check the
'Verify after Backup'.
----------
*Passwords*
If you are using the QIC file system with the Password option, only 8
characters are significant even though DualStor will accept 15
characters. All 15 characters are significant when using the DualStor
file system.
----------
*Hardware Compression*
The DualStor User's Guide shows a Hardware Compression radio button
on the Backup Set Parameters windows but you will not see it in the
application itself as DualStor does not support any tape drives that
support Hardware compression.
----------------------------------------------------------------------
8 - ERRORLEVEL RETURN CODES FOR BATCH FILES
----------------------------------------------------------------------
You can use ERRORLEVEL to check the return codes of a DualStor
tape operation if you are using job files and batch files.
The values returned by DualStor in ERRORLEVEL are as follows:
0 = No errors, successful completion
1 = No tape cartridge in drive
2 = Tape is full, cannot write
3 = Tape is write protected
4 = Mount failed or incompatible tape
5 = Invalid command line arguments
6 = Fatal disk error
7 = Not enough memory available to run
8 = No tape drive present
9 = User aborted operation
10 = Fatal tape error
11 = Critical verify failure, backup set deleted
12 = Internal software error
13 = Disk full on restore
14 = Disk full in \temp directory
15 = No files selected
16 = DUALSTR.MSG file not found
17 = Non-critical verify warning (Verify miscompares seen in Session log)
The following line is an example of the contents of a job
file to retension the tape first. The 'Do not wait for errors'
option is set on. Let's call the job file RETEN.TPF:
!util /w 0 /r
The following line is an example of the contents of a job
file to backup the C: drive. It will scan checked files, not wait
on error, name the backup set and backup the C: drive. Let's call
the job file MYBACKUP.TPF:
!backup /m /w 0 /n "MYBACKUP" /s C:\*.*
The following DOS batch file is an example of how you might
use the DualStor return codes and the above DualStor job
files. Let's call the batch file TAPEOPS.BAT:
rem --------Beginning of Sample Batch program-------------------
@echo off
rem
rem Log Retension tape start message to TAPEOPS.LOG file
echo Execute DualStor job file to retension tape >>.\tapeops.log
DUALSTR reten.tpf
rem next statement checks for errorlevel = 1 or greater
if errorlevel 1 goto checkrc
echo Retension tape successful >>.\tapeops.log
rem
rem Log Backup start message to log file
rem Execute DualStor job file to backup C: drive >>.\tapeops.log
DUALSTR mybackup.tpf
rem next statement checks for errorlevel = 1 or greater
if errorlevel 1 goto checkrc
echo Backup of C: successful >>.\tapeops.log
goto end
rem
rem Check which error DualStor found and go process the error
:checkrc
if errorlevel 16 goto nomsgfl
if errorlevel 15 goto noflsckd
if errorlevel 14 goto diskfull
if errorlevel 13 goto diskfull
if errorlevel 12 goto softerr
if errorlevel 11 goto verfyerr
if errorlevel 10 goto tapeerr
if errorlevel 9 goto userabrt
if errorlevel 8 goto nodrive
if errorlevel 7 goto memerr
if errorlevel 6 goto diskerr
if errorlevel 5 goto invcl
if errorlevel 4 goto inctape
if errorlevel 3 goto wptape
if errorlevel 2 goto tapefull
if errorlevel 1 goto notape
rem
rem Here is examples for a few of the return codes:
rem
:inctape
echo Either the mount failed or the tape is incompatible,
echo Check the tape condition and restart TAPEOPS.BAT
pause
goto end
rem
:notape
echo There is no tape in the drive, please insert a tape and
echo restart TAPEOPS.BAT
pause
goto end
rem
:end
echo End of TAPEOPS.BAT >>.\tapeops.log
rem ------------End of Sample Batch program---------------------
TAPEOPS.BAT, RETEN.TPF, and MYBACKUP.TPF would all reside in the
directory where DualStor is installed. The above example would
be executed by typing 'TAPEOPS.BAT' on the command line at the DualStor
directory DOS prompt (\DUALSTOR\TAPEOPS.BAT).
