Welcome to the Demo Version of the IBM DualStor Backup Program for Windows Version 2.0! All operations of the DualStor for Windows 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 Windows diskette in a 3.5" floppy drive and enter 'x:setup' where x=your 3.5" floppy drive designator (for example, a:setup) from the Windows Program Manager File pull-down, Run option. After DualStor for Windows is installed and after you have restarted Windows, double-click on the DualStor group to open the DualStor group and then double-click on the DualStor icon to start the DualStor application. We hope you like DualStor! If you would like to purchase DualStor for Windows you can call Options by IBM at 1-800-426-7299 (US Only) or IBM Direct at 1-800-465-7999 (Canada Only). DualStor for DOS and DualStor for Windows versions 2.0 are packaged together.

DualStor part numbers: 11H1594 DualStor for DOS/Windows version 2.0 (software only) 11H1504 DualStor for DOS/Windows version 2.0 and DualStor 450 Tape Drive (hardware, software, & 1 Sony QIC-wide QW5122XL tape cartridge) 11H1568 DualStor for OS/2 version 2.0 (software only) 11H1505 DualStor for OS/2 version 2.0 and DualStor 450 Tape Drive 11H1571 Upgrade from DualStor for DOS/Windows 1.0x 11H1549 Upgrade from DualStor for OS/2 1.0x The following is the README that ships with the product. ---------------------------------------------------------------------- TABLE OF CONTENTS 1 - DualStor Execution 2 - DualStor and Windows 3 - DualStor Job (Parameter) Files 4 - DualStor and Networks 5 - Compatibility with Other Software and Hardware 6 - DualStor 2.0 Changes from Versions 1.x 7 - Miscellaneous ---------------------------------------------------------------------- 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.
