----------------------------------------------------------------------
1 - DUALSTOR EXECUTION
----------------------------------------------------------------------
*Undocumented Copy/Paste Capability*
In the Session Logs window, the Control menu includes a copy
capability not documented in the User Manual. Select text -- either by
clicking on one or more lines with your mouse or by using the Select
All option -- and then select Copy. The selected text will be copied
to the clipboard and can be pasted into another application that has a
paste command.
----------
*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.
----------
*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:
DUALSTRW.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 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 B
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 DUALSTRW section of your
DUALSTRW.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 the A:, B:,
C:, and D: drives).
You could add the following statement to your AUTOEXEC.BAT instead.
SET IRSKIPDISK=abcd
----------------------------------------------------------------------
2 - DUALSTOR AND WINDOWS
----------------------------------------------------------------------
*Floppy Drive Access*
To access a floppy drive while DualStor is running in the background,
do so from within Windows, using either the File Manager or the "Run"
command on the Program Manager's File menu. You will not be able to
access a floppy drive from the DOS prompt while DualStor is running.
----------
*Accessing Windows Setup*
If you are running DualStor and want to access Windows Setup, you must
first exit DualStor. Otherwise, your system may hang when you attempt
to exit DualStor after finishing with Windows Setup.
----------
*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.
----------
*DualStor and LANtastic Security Files*
To perform a full backup or restore of LANtastic security files:
1. Connect your tape drive directly to the LANtastic file server.
2. Make sure DualStor for Windows is installed on the server.
3. In DOS, go to your Lantastic install directory (the default is
C:\LANTASTI) and type SERVER/REMOVE.
This will disconnect all workstations from the server so that
files are not open on the network during backup or restore
(DualStor does not back up or restore open files).
4. Perform a backup or restore in DualStor as you normally do.
This procedure is only necessary when you back up or restore LANtastic
security files. Otherwise, you can use normal procedures recommended
in the DualStor User Manual, such as connecting your tape drive to a
network workstation.
----------
*IBM Models 8580 and 8590 and LANtastic*
If you are using an IBM model 8580 or 8590 with LANtastic, you need to
contact Artisoft technical support 602-293-6363 for information on
removing a server without causing a general failure error.
----------------------------------------------------------------------
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 Windows you should remove any of its device driver
entries from your SYSTEM.INI before trying to execute DualStor
for Windows.
----------
*DMA Channel 2*
Prior to executing DualStor for Windows make sure you have no
entries in your SYSTEM.INI that are using DMA Channel 2.
----------
*National Semiconductor Floppy Controller DP8473*
If the DualStor for Windows 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.
----------
*IBM Model 9577 and 4100MC Card*
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.
----------
*DualStor and Migrating Windows Applications to OS/2*
If you have DualStor for Windows installed on your system and
you install OS/2, do not migrate the DualStor for Windows to the OS/2
Desktop. DualStor for Windows will not work properly in the Win-OS/2
session. If you did migrate DualStor for Windows to the OS/2 Desktop,
you should delete the DualStor for Windows folder.
----------------------------------------------------------------------
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.
