Installing Seagate Backup After Other Backup Programs ------------------------------------------------------------------------------------- You may experience difficulty running Seagate Backup if some device files from other backup programs are found in your SYSTEM.INI file. If you can't start Seagate Backup, 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. 2. Exabyte 2MB High-Speed Controller DMA Conflict ------------------------------------------------------------------------------------- Because of several potential addressing conflicts, the Exabyte 2MB High-Speed Controller Card DMA setting should only be set to DMA Channel 1. 3. Video/DMA Conflict Problems ------------------------------------------------------------------------------------- Seagate Backup uses direct memory access (DMA) channels to read and write data. Sometimes using a tape device that is connected to the floppy controller causes conflicts with the Windows 3.1 video drivers. During the compatibility test, Seagate Backup determines if your system has a video/DMA conflict and if so, goes through a series of tests in an effort to ensure your system runs reliably with Seagate Backup. After each test a message will inform you that tests are still being performed. If Seagate Backup has attempted every test and your system will still not work reliably, a message will inform you of the problem. NOTE: If you experience video/DMA conflicts, try disabling the Video Caching option (sometimes referred to as Video Shadowing) in your CMOS setup. If your system locks up when using the backup program, switch to the Windows Standard VGA driver. If the Windows Standard VGA driver works, contact your video board manufacturer for an updated driver. 4. 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 Seagate Backup, 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. 5. Hardware Compression Not Supported ------------------------------------------------------------------------------------- Seagate Backup for Windows, Version 5.3, does not support the hardware compression function found on some high-speed controller cards. 6. Installing With Third-Party Windows Shells ------------------------------------------------------------------------------------- If you use a third-party Windows shell program such as PCTools or Norton Desktop for Windows, Seagate Backup may not install correctly. If you experience difficulty installing Seagate Backup 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. 7. 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. 8. 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. 9. 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 If you are running Windows 3.1, 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. If you are running Windows 95: 1. Double-click the My Computer icon. 2. Double-click the Control Panel icon. 3. Double-click the System icon. 4. Click the Device Manager tab in the System Properties window. The device Manager tab appears. 5. Select the hardware that you want to change settings for, then click Properties. The Properties window appears. 6. Click the Resources tab in the Properties window. 7. Deselect Use Automatic Settings. 8. To change your Input/Output Range, Interrupt Request, or Direct Memory Access settings, highlight the item and click Change Setting. Make any changes and click OK. 9. Close the System control panel. 10. Shut down your computer. 11. If necessary, make any changes to your high-speed controller card's settings and install it in your system. See your hardware manual for instructions. 12. Restart your computer and Windows 95. Symptoms of an IRQ conflict include Seagate Backup not finding the tape controller and network problems when backing up to tape. 10. Potential Conflict with Screen Savers ------------------------------------------------------------------------------------- Some screen savers will not activate while a backup, compare, or restore is running and Seagate Backup is minimized. For optimum performance, we recommend that you disable your screen saver while using Seagate Backup. However, if you wish to use your screen saver, you must first make sure Seagate Backup is not minimized. 11. Encrypted Backup Sets ------------------------------------------------------------------------------------- Seagate Backup cannot restore backup sets encrypted by other backup programs. You must use the original software to restore them. 12. 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. 13. Files Not Backed Up by Seagate Backup ------------------------------------------------------------------------------------- Seagate Backup 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 (Windows 3.1x only) WIN386.SWP 14. Changes to Files During Installation ------------------------------------------------------------------------------------- Windows 3.x The following lines are added to the [386Enh] section of your SYSTEM.INI file: DEVICE=C:\WINDOWS\SYSTEM\DRVWCDB.VXD DEVICE=C:\WINDOWS\SYSTEM\DRVWPPQT.VXD DEVICE=C:\WINDOWS\SYSTEM\DRVQ117.VXD Windows 95 The following files are placed in your C:\WINDOWS\SYSTEM\IOSUBSYS directory and are loaded by the Windows 95 at start up time: DRVWCDB.VXD DRVWPPQT.VXD DRVQ117.VXD 15. 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. 16. Verify Your First Backup ------------------------------------------------------------------------------------- When you make your first backup with Seagate Backup, it is highly recommended that you use the Compare After Backup option. During the Verify phase, Seagate Backup 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 Seagate Backup 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. 17. Troubleshooting High-Speed Controllers ------------------------------------------------------------------------------------- To properly set up your system, you should avoid using an interrupt request (IRQ) that is used by another device (i.e., mouse, sound card, network card, scanner, etc.). Some common IRQs that may already be used in your system include: IRQ 3 COM 2, 4 ports IRQ 4 COM 1, 3 ports Symptoms of an IRQ conflict include Seagate Backup not finding the tape controller and network problems when backing up to tape. IRQ usage can be determined by using the Microsoft Diagnostics Program. Exit Windows and type MSD at the DOS prompt. 18. Supported SCSI Controllers ------------------------------------------------------------------------------------- The following SCSI controller cards are supported by this software: Adaptec AHA-1510 Adaptec AHA-152x Adaptec AHA-1530P Adaptec AHA-1540B Adaptec AHA-1542B Adaptec AHA-1542C Adaptec AHA-1640 Adaptec AHA-2842A Adaptec AHA-2930 Adaptec AHA-294x Adaptec AHA-3940 Adaptec AHA-3940w Adaptec AHA-398x Adaptec AHA-78xx AMD PCI SCSI Buslogic BT445C Buslogic FlashPoint LT (BT930) Future Domain TMC-1670SVP Future Domain TMC-1680 Western Digital 7296A 19. Performance Issues on QIC-3020 Parallel Port Tape Drives ------------------------------------------------------------------------------------- If you have a QIC-3020 Parallel Port tape drive you may experience a performance limitation, especially on systems with unidirectional parallel ports. This combination may not transfer data from the tape drive to the system fast enough to allow the tape to run continuously, or "stream." However, if you reformat the tape using the QIC-3010 format, the tape will run at half the speed of a QIC-3020 and stream more of the time. This will result in faster net restore times and less wear on the tape drive, but will cut the tape's capacity in half. 20. Support for Tape Drives Using Hardware Compression ------------------------------------------------------------------------------------- Some SCSI tape drives contain specialized hardware which performs compression significantly faster than that performed by software using the system processor. Because of this large performance gain, hardware compression is always used in preference to software compression on these drives. If hardware compression is being used during a backup, the progress screen displays Hardware Compression as the compression type. If a tape is used in a drive that does not support the identical hardware compression as the original drive, the backup sets will be unreadable. In order to be compatible, the backup must be made with hardware compression disabled in the Settings Screen. NOTE: By default, this program uses hardware compression. If you do not want to use hardware compression, disable the hardware compression option. 21. Controller Conflicts ------------------------------------------------------------------------------------- The Promise 2300 EIDE VLB controller must run in fast mode (/f parameter) in order to work with floppy tape drives. 22. ASPI SCSI Manager Requirements ------------------------------------------------------------------------------------- An installed and configured ASPI Manager for the system SCSI controller is required for use of Seagate Backup with SCSI tape drives and optical drives. Refer to your SCSI controller or system manual for availability of an ASPI manager for your controller. 23. PD Conflicts Can Result in Data Loss ------------------------------------------------------------------------------------- CAUTION: Do not select files from your PD cartridge for backup if the PD drive has been selected as the backup device. All files on the PD cartridge are erased before the backup begins. If you are using a PD cartridge for backup and another application accesses the same PD cartridge during the backup, all existing files may be deleted from the cartridge. Due to the asynchronous nature of the File Manager display, files may still appear to be on the PD cartridge after they have been deleted. Once you remove and reinsert the cartridge or reboot your system, the files will not appear. 24. Conflict with QuickBooks for Windows ------------------------------------------------------------------------------------- If you run Intuit's QuickBooks for Windows, restart Windows before running Seagate Backup. There is a conflict between Intuit's QuickBooks for Windows and Seagate Backup. 25. Known Incompatibilities ------------------------------------------------------------------------------------- The following incompatibilities exist between Seagate Backup for Windows 95 and other programs: 1) Seagate Backup is incompatible with all Norton Utilities. Make sure that these programs are not running during backup and restore operations. Additionally, the Norton file FSVUNDO.DAT is not automatically excluded by Seagate Backup during operations and may cause an error during file verify. 2) Installing Seagate Backup on to a disk drive that has been compressed with Stacker95 may cause the system to lock up. The program should not be installed on hard drives using this compression. 26. Archive Bit ------------------------------------------------------------------------------------- The archive bit on a file is removed immediately after it is backed up. If the user cancels a backup operation in mid-progress, the archive bit for some files will be removed even though the files are not backed up. If a backup is canceled, it is recommended that a full backup be performed immediately to guarantee that all files are safely stored. 27. Updated Version of Third Party Drivers ------------------------------------------------------------------------------------- Please make sure you have the most recent versions of third party drivers for Windows 95 installed. An example of these would be drivers for SCSI controllers. 28. Possible problems with IDE chipsets ------------------------------------------------------------------------------------- Windows 95 On some PC's, the Windows 95 operating system software is unable to properly recognize and configure the IDE chipset, which controls the IDE hard disk, CD-ROM, and IDE tape drive. If this is the case, Windows 95 forces access to IDE devices to occur sequentially, sometimes referred to as serialized access. Serialized access implies each IDE operation must complete before the next access can begin. Normally the delays caused by sequential operation are not obvious because hard drive and CD-ROM accesses complete quickly. However when using the IDE tape backup device, there are certain tape operations that require longer periods of time to complete, such as a tape retension. In such a case, a noticeable delay in accessing the other IDE devices occurs, causing a delay in response while the system waits for the IDE tape operation to complete. If you experience these unusual delays when using the IDE tape backup device, it may be necessary to obtain a third party IDE controller card. Windows 3.1x Under Windows 3.1x, a related problem may occur, where IDE hard drives and IDE tape drives conflict. This can be eliminated by forcing the devices to be accessed sequentially, by choosing SERIALIZE I/O in the configuration window. While this will cause performance degradation, as described above, it may be required to get some drive/controller combinations to work. 29. Long File Name Access ------------------------------------------------------------------------------------- The maximum length of a path is 260 characters. If you have a path that exceeds this length, Windows considers it invalid and Seagate Backup cannot back up the files and directories in the path. The Explorer will not allow you to view the files if the path exceeds 260 characters, however they are accessible through short file names and DOS. To view or back up the files and directories in this path, ensure the full path length does not exceed 260 characters. 30. Lost SCSI Tape Space Due to Canceled Backups ------------------------------------------------------------------------------------- If you are using a SCSI tape and you select Cancel during a backup operation, the tape space used for the backup job up to that point is unrecoverable until you initialize the tape. 31. Problems with Printer Connections to PPT Drives ------------------------------------------------------------------------------------- If your printer is connected to the PPT tape drive, please check the following: 1. Make sure the PPT tape drive's power is on. 2. During a printing operation, make sure you are not backing up to any PPT devices. 32. Restoring QIC-80, 3010, and 3020 Backup Tapes ------------------------------------------------------------------------------------- In rare cases, a valid tape may be reported as not readable by a drive. The drive will either continue to prompt for a tape to be inserted, or report an unrecoverable hardware error. To restore data from the tape in this case, use the tape drive and software that created the backup.
