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. If your drive supports AccuTrak tapes, you should purchase them preformatted. 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 2.1.2, 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 may 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 2.1.2, 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 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. 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. Backing Up Large Numbers of Files to AccuTrak Tapes ------------------------------------------------------------------------------------- When using AccuTrak tapes, backing up a very large number of files--approximately 30,000 to an 80MB tape or 45,000 to a 120MB tape--will result in an error. Divide the files into two or more backup sets and back up each set to its own tape. 18. NetWare Server Information and AccuTrak tapes ------------------------------------------------------------------------------------- Because of the proprietary format used by the tapes, NetWare bindery files, trustees, and extended attributes cannot be backed up to AccuTrak tapes. 19. NetWare Files With an Execute Only (X) Attribute ------------------------------------------------------------------------------------- NetWare files with an execute only (X) attribute will not be backed up, compared, or overwritten during a restore. 20. 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 WIN386.SWP NetWare System files: BACKOUT.TTS NET$SPL.QUE NET$MSG.SYS DIRSTAMP.SYS NET$OBJ.SYS* NET$PROP.SYS* NET$VAL.SYS* NET$BIND.SYS* NET$BVAL.SYS* SYS$LOG.ERR * These NetWare bindery files will be backed up or restored only if you are logged on to a server as Supervisor. See your User Guide for more information. Additionally, Conner Backup Exec will not back up a number of temporary files used by the program when these files are found in the program's directory. 21. 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. 22. 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 If the Load With Windows checkbox in the Backup Scheduler is checked, the following item is added to WIN.INI [Windows] load= line: load=[qbwin install path]\scheduler.exe This item is removed from the load= line when the checkbox is unchecked and the Backup Scheduler is closed. 23. 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. 24. 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. 25. 3020 Drive Requirements ------------------------------------------------------------------------------------- To achieve optimal performance with a 3020 drive, a 1Mbit controller or higher (2Mbit) is required. 26. Controller Conflicts ------------------------------------------------------------------------------------- The Promise 2300 EIDE VLB controller must run in fast mode (/f parameter) in order to work with floppy tape drives. 27. 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 and ATI Ultra Mach 32/64 cards. 28. 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. NOTE: See your Windows manual for more information. 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. Notice 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 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.
