SYMANTEC CORPORATION - PETER NORTON GROUP Readme for Norton Backup Version 3.0 for Windows WELCOME TO THE NORTON BACKUP! ============================= This document contains important information not included in the user documentation. For easiest reading, maximize this window by clicking the Maximize button (Alt+Spacebar, X). This file contains the following sections: 1. Performing an Automatic Backup the First Time 2. Unattended Backup and Norton Desktop's Screen Saver 3. Installing DOS 6.0 After Norton Backup for Windows 4. Norton Emergency Restore 5. Compatibility with Norton Backup for DOS (Ver. 1.2 & 2.2) 6. Configuring SCSI Devices 7. Networks/NetWare Bindery 8. Network Tape Sharing 9. Floppy Drives and DOS Path 10. SCSI/QIC-02 Tape Devices 11. QIC-40/80 and IDE Tape Drives 12. Supported AccuTrak Tape Drives 13. InfoServer 14. Windows Standard Mode 15. System Font 16. Correctable Errors 17. Compressed Drives 18. Hardware/Software Incompatibilities 19. Limitations 1. PERFORMING AN AUTOMATIC BACKUP THE FIRST TIME ================================================ The first time you perform an automatic backup, Norton Backup stops to ask for a description of the backup set. Confirm the name in the text box or type in a new one, then be sure to check the Always Use This Description check box before you click OK. Thereafter, Norton Backup will not prompt you for a backup-set description. 2. UNATTENDED BACKUP AND NORTON DESKTOP'S SCREEN SAVER ======================================================= If you have an unattended Backup scheduled to take place and a password is set in Norton Desktop's Screen Saver, you should configure Screen Saver to disable the "Wake on Mouse Clicks" option. This will allow the scheduled backup to occur unattended. 3. INSTALLING DOS 6.0 AFTER NORTON BACKUP FOR WINDOWS ===================================================== DOS 6.0 installs an older version of the VFINTD.386 into the DOS directory and then modifies the SYSTEM.INI file (DEVICE=C:\DOS\VFINTD.386). If you install MS-DOS 6.0 after Norton Desktop 3.0, the next time you launch Norton Backup 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 Norton Backup will save the existing SYSTEM.INI as SYSTEM.NBW and make the necessary change to the "DEVICE=" line in 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=[NDW install path]\VFINTD.386. 4. NORTON EMERGENCY RESTORE =========================== The following tape drives and configurations are NOT supported by Norton Emergency Restore on the Norton Desktop Fix-It Disk: -IBM PS/2 model 40 used with the Archive 5240 tape drive as a B: drive -Colorado AB-10 adapter card used with a Colorado Jumbo 120 or DJ-10 tape drive that has a firmware version of 39 or earlier -SCSI and QIC-02 tape drives -IDE tape drives -Irwin AccuTrak tape drive series 5. COMPATIBILITY WITH NORTON BACKUP FOR DOS (VER. 1.2 & 2.2) ============================================================ If you are a user of Norton Backup for DOS and are currently in the middle of a FULL/INCREMENTAL or FULL/DIFFERENTIAL backup cycle, you should not have to interrupt that cycle and start over. In fact, you should be able to use either product to create your next backup volume. Symantec strongly recommends, however, that you confirm you'll be able to do this by first using Norton Backup for Windows to restore some files that were backed up with Norton Backup 1.2, 2.0, or 2.2 for DOS. If you encounter any errors while restoring, there may be some limitation(s)--either hardware or software--that inhibits compatibility with older Norton Backup volumes. If this is the case, you should start the cycle over by making a full backup of all your drives before resuming your routine. 5.1 Setup Files --------------- If you are planning on using the same Setup files for both Norton Backup for DOS and Norton Backup for Windows, use include and exclude statements to describe file selections. Manual file selections made in the Windows product cannot be read by the DOS product. 5.2 Data Verification --------------------- If data verification in your setup file was set to "Read Only" in Norton Backup for DOS (versions 1.0 and 1.2), be sure to check your settings in Norton Backup for Windows when you first load that setup file. The "Read Only" option does not exist in Norton Backup for Windows and the setting will default to "Read and Compare" or "Compare After Backup." Change this setting if you prefer a different option. 5.3 Macro Compatibility ----------------------- If you plan to use setup files that were created with Norton Backup for DOS, you will need to re-create any macros that were associated with those setup files. 6. CONFIGURING SCSI DEVICES =========================== 6.1 Resolving Configuration Problems ------------------------------------ If you are having trouble configuring your SCSI drive, try the following: 1. Make sure that the drive supports the tape being used. 2. Make sure the chain is properly terminated (if using only one device, it must be terminated). 3. Make sure the terminators are not plugged in backwards. 4. If an external device is the last device in the chain, make sure that it is powered on (in order for the terminators to be effective). 5. Try turning off sync negotiation. 6. Try turning off parity. 7. Try turning off disconnect. 8. Make sure 1-3 devices (including the adapter) are supplying termination power. 9. Remove all but 1 device from the chain. 10. Minimize cable length (1 foot). 11. Remove disk cache programs. 12. Verify that each SCSI device on the chain is set to a unique SCSI ID. 6.2 Hanging When Searching for Devices -------------------------------------- If your system hangs while searching for SCSI devices, it may be due to an address conflict with the SCSI host adapter or a SCSI ID conflict. Verify the addresses or SCSI IDs being used and try again. 6.3 Multiple SCSI Adapters -------------------------- If you are using a Future Domain driver and also have a path to WINASPI.DLL, strange characters may be displayed on the screen when using Norton Backup for Windows. To solve this you can either temporarily rename or delete the WINASPI.DLL file. 6.4 PS/2 Model 30/Mountain Mach II Card --------------------------------------- Using the default address settings on the Mountain Mach II card in a PS/2 Model 30 will cause the system to lock up. The default DMA setting on the high-speed controller and the hard drive are both 3. Change the DMA setting on the card before configuring with Norton Backup. 7. NETWORKS/NETWARE BINDERY =========================== 7.1 Maximum Path Size Supported ------------------------------- Currently, Norton Backup does not support paths that are greater than 63 characters. 7.2 Restoring NetWare Bindery ----------------------------- After restoring netware bindery to a server, it is a good idea to run BINDFIX from the server. Use the BINDFIX command at the SYS:SYSTEM prompt to update the bindery with any user changes that may have occurred since the backup. For more information, refer to the Novell NetWare Utilities Reference manual. 7.3 Trustee Information ----------------------- Trustee information cannot be restored if you select a Restore To option other than Original Location. 8. NETWORK TAPE SHARING ======================= The minimum requirements to run Share are IPX 3.10 or IPXODI 1.2. It is recommended that you use IPXODI. If you experience network connection losses or timeout errors during a share session, verify that the versions of IPX and Net Shell are correct. 8.1 Share Retries ----------------- For networks with heavy traffic, the "Share Retries" setting can be added to the NDW.INI file. This will allow you to adjust the number of times Norton Backup will attempt to share a device. By default, Norton Backup will attempt to share the device every half a second 220 times. This setting can be adjusted according to your network's traffic. To add this setting to the NDW.INI file: 1. Open the NDW.INI file using a text editor. 2. Search for the [NBACKUP] section. 3. Add the following line to the end of the [NBACKUP] section: share retries = x (where x represents the desired value). 8.2 Windows Standard Mode ------------------------- Currently, when running in Windows Standard mode there may be problems allocating enough memory to use the Share feature. Attempting to share can cause the "Unable to create DMA buffers" message and Norton Backup will quit on machines with 2 to 4 MB of installed memory. 9. FLOPPY DRIVES AND DOS PATH ============================= 9.1 Using a 360K Diskette in a 1.2 MB Drive ------------------------------------------- Performing backups to 360K diskettes in a 1.2 MB floppy drive is not recommended, and will almost surely result in lost data when attempting to restore. However, Norton Backup for Windows does support backups to 360K diskettes in 1.2 MB floppy drives in order to allow file transfer between older and newer computers. The best method to do this is to format the diskettes in the 360K drive, then back up using the "DOS Path" option in the Backup To combination box, and the 360K component size setting in the backup options (General category). Even when this procedure is used, these diskettes should not be relied upon as the sole backup of a hard disk. 9.2 Floppy Drive Contention --------------------------- Norton Backup for Windows allows you to switch to other applications while backing up or restoring data. To ensure that access to the floppy drives or tape drive is not interrupted during this process, Norton Backup hides these drives from all other applications. Programs that display a list of available drives may not display drives A: and B: during these background operations. For the same reason, you should not try to access your floppy drives directly. For example, typing FORMAT A: in a DOS window while using Norton Backup to back up to a floppy drive will produce an "invalid drive specification" or "drive not ready" system message. Normal use of the drive will return once the backup is finished. Note that this is also true when using a QIC 40/80 or AccuTrak tape drive that is connected to the floppy controller as a B: drive. When using high-speed controllers or adapters with a QIC-40/80, AccuTrak, IDE, or QIC-02 drive, you will be prevented from using the floppy drives only if the controller card is using DMA 2 or IRQ 6 (sharing the same addresses as the floppy diskettes). When using SCSI tape drives, floppy drive access is not restricted. 9.3 Data Verification vs. Compare Function ------------------------------------------ To safeguard your data you should take the time to check that the data written to your diskettes matches the data on your hard disk. You can do this through Data Verification while the backup is in progress, or by using the Compare function after the backup is completed. Data verification during a floppy or DOS path backup verifies the reliability of the media more than the data itself. For this reason, it is safest to also perform a Compare after the backup (using the Compare function), which will verify that the compressed form of the original data was not corrupted when transferred into memory. 9.4 Compare Function -------------------- Compare is a separate function designed to provide maximum data security. The data in the backup set is compared to the source data on the hard disk using the following procedure: 1. Reads the data on your backup medium exactly as if it were going to restore the data to the hard disk. 2. Compares this data to the data found on the hard disk. 3. Verifies that the files are identical and displays a message if they do not match. 10.

You can install them using the supplemental or custom install feature. The benefits of using WINASPI are the ability to run multiple DOS boxes and increased performance. 10.4 SCSI Wangtek 6130/Adaptec 1520 or 1542C card -------------------------------------------------- The Wangtek 6130 tape drive and an Adaptec 1520 or 1542C card are not supported configurations. 10.5 SCSI Security Erase ------------------------ Security Erase on some SCSI tape drives may take as long as 6 hours. 10.6 Incompatible Tape Cartridges --------------------------------- Using tapes that are incompatible with the drive can cause your system to "hang." Reboot your system and verify that you are using a tape cartridge that is compatible with your drive. 10.7 Low Capacity DC6000 Tape Cartridges (250 MB or less) --------------------------------------------------------- At this time, backups made with low capacity DC6000 tape cartridges (250 MB or less) can only be restored with Norton Backup. If you plan on restoring a backup set made by Norton Backup with another vendor's software, use high capacity tapes (320 MB or greater) to make the backup. 10.8 SCSI - Tapes Used With Other Backup Software ------------------------------------------------- Tapes that have been used with other backup software may cause unexpected behavior when used in Norton Backup. Initializing these tapes with Norton Backup will solve the problem. To Initialize a tape: 1. Insert the tape in the SCSI device. 2. Select Initialize from the Tape Tools menu. NOTE: If you experience this problem during the compatibility test, initialize the tape and rerun the test. 10.9 SCSI Chain Termination --------------------------- If you experience unusual problems during tape operations, insure that the SCSI chain is properly terminated. Please refer to your SCSI device installation manual for more details. 10.10 Manual Add - SCSI ----------------------- You cannot manually add a SCSI or InfoServer device in Norton Backup. The Manual Add feature, when used for SCSI and InfoServer, is for troubleshooting purposes only. However, this feature will display the number of SCSI and InfoServer drives and/or errors detected. 10.11 QIC-02 Maynard Controllers and Drives ------------------------------------------- At this time, Norton Backup does not support Maynard controller cards or drives. 10.12 Hardware Compression -------------------------- If your SCSI tape drive has hardware compression and Norton Backup does not detect it, ensure that the hardware compression switch on the tape drive itself is on. Hardware compression can be turned on and off from the Hardware Compression checkbox in the Settings dialog box (Configure window). To change the compression setting: 1. Click the Configure button. 2. Select the desired SCSI device. 3. Select the Settings command... button. 4. Set the Hardware Compression checkbox to the desired setting. NOTE: When hardware compression is turned on, software compression alternatives will not available in the Backup General options window. 10.13 SCSI Device Troubleshooting --------------------------------- If your SCSI device light begins to flashes or if Norton Backup starts to "hang" during tape operations, it's possible that the device needs to be cleaned. Please refer to the user's manual for information on the device's flash codes and cleaning recommendations. 11. QIC-40/80 and IDE TAPE DEVICES ================================== 11.1 Supported QIC-40/80 Tape Drives ------------------------------------ This section lists the QIC 40/80 tape drives that are supported by Norton Backup. MANUFACTURER MODEL NAME --------------------------------------------------------------------- Aiwa TD-803 Aiwa TD-811 Alloy Computer Products Retriever 250 Archive Corporation 5240 Archive Corporation 5580, 3580 Archive Corporation SuperHornet 51250/31250/11250 CMS Enhancements CMS-40 Colorado Memory Systems Jumbo 120 Colorado Memory Systems Jumbo 250 Compaq Computer Corp. 80/120 CORE International COREtape Light Iomega Tape250 Insider, Insider HH, PC Powered Irwin SX Series 40 MB and 80 MB Mountain Network Solutions FileSafe 4000 Mountain Network Solutions FileSafe 8000 Plus, Mountain 80 Summit Memory Systems, Inc.

The tapes formatted by this machine are QIC-40 compatible; however, the tape drive is not QIC-117 interface compatible. 11.2 QIC-40/80 High-Speed Controllers -------------------------------------- The following high-speed controller cards are supported by Norton Backup: Colorado FC-10 Colorado TC-15 Colorado TC-15MC Iomega Summit Tecmar Wangtek Irwin 4100 Irwin 4100MC Mountain MACH II Mountain MACH II MC 11.3 Supported IDE Tape Drive and Adapter ----------------------------------------- This section lists the IDE tape drive and adapter that is supported by Norton Backup. MANUFACTURER MODEL NAME ADAPTER -------------------------------------------------------------- Summit Memory Systems, Inc. SE305 Summit Adapter NOTE: Norton Backup may not be able to read or write to tapes written to by the old Summit SE305 drive until they are formatted by Norton Backup. The older Summit SE305 drive can be distinguished by the orange logo on the face plate and the model number. Old Summit Drives - FAB 03-33163-01 Rev. B New Summit Drives - FAB 03-33205-01 Rev. B 11.4 Colorado TC-15 Hardware Compression ---------------------------------------- Hardware compression can be turned on and off from the Compression drop-down list box in the Settings dialog box (Configure window). To change the compression setting: 1. Click the Configure button. 2. Select the QIC-80 device. 3. Select the Settings command... button. 4. Select the desired setting in the Compression drop-down list box. NOTE: When hardware compression is turned on, software compression alternatives will not be available in the Backup General options window. 11.5 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 and 4 ports IRQ 4 COM 1 and 3 ports Symptoms of an IRQ conflict include Norton Backup not finding the tape controller and network problems when backing up to tape. 11.6 Video/DMA Conflict Problems -------------------------------- Norton 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, Norton 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 Norton Backup. After each test a message will inform you that tests are still being performed. If Norton 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. 11.7 Hard Drive Cable Support - IDE ----------------------------------- Operating an IDE drive on the same cable as the hard drive is supported in Windows Standard mode only. 12. SUPPORTED ACCUTRAK TAPE DRIVES ================================== This section lists the AccuTrak tape drives that are supported by Norton Backup. AccuTrak drives require pre-formatted tapes. MANUFACTURER MODEL NAME ------------------------------------------------ Irwin Magnetic Systems A120, 2040 Irwin Magnetic Systems A250, 2080 Irwin Magnetic Systems A250xxST, 2120 13. INFOSERVER =============== Backups created on InfoServer tapes are only readable on InfoServer tape drives. InfoServer tape drives cannot read a backup made by a drive not connected to an InfoServer. 14. WINDOWS STANDARD MODE ========================= 14.1 Using DOS Boxes -------------------- Shelling out to DOS under Windows Standard mode is not supported when using Share, a SCSI, IDE, or InfoServer tape device. 15. SYSTEM FONT ================ 15.1 Sharing Violation ---------------------- If you have SHARE.EXE loaded, you may receive a sharing violation on the file "Arial.ttf" during backups. Because the file is being used by the system, it is open at the time Norton Backup is trying to back it up. Skip this file and continue with the backup. 16. CORRECTABLE ERRORS ====================== If you are getting excessive correctable errors during compare or restore, check the following: 1. Make sure that the drive is grounded. 2. Make sure that the drive is clean. 3. Make sure that your "BUFFERS=" statement in your CONFIG.SYS file is set to 30 or greater. 4. After you've retrieved the data from the tape, use Tape Tools Format or [SCSI/QIC-02] Tape Tools Erase. Or, use a newer tape. Norton Backup recommends that the "BUFFERS=" statement be set to 30 or greater even if using a disk caching program. A low buffer statement may lead to excessive correctable errors and thus directly affect the performance of your backup or restore. NOTE: If the number of errors corrected is more than the errors found, make sure that the Burst Mode setting is off. To change the Burst Mode setting: 1. Click the Configure button. 2. Select the QIC-80 or AccuTrak device. 3. Click the Settings... command button. 4. If active, uncheck the Burst Mode check box. 16.1 How Many Correctable Errors are Acceptable? ------------------------------------------------ It is acceptable to have up to 50 correctable errors on a full tape. If you have tried all the steps in section 18 above, but are still exceeding 50 errors, contact technical support. 17. 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. 18. HARDWARE/SOFTWARE INCOMPATIBILITIES ======================================= 18.1 Notebook Power Management Feature -------------------------------------- Running some notebook computers with the power management option on may cause problems when using Norton Backup. To avoid power loss during backup operations, disable the power management option: Zenith - Set the Floppy Disk Drive Power Management option to "Full Auto." Gateway - Run SETPOWER /L0. Texas Instruments - Run SETPOWER /L0. If you experience problems with another brand of notebook computer, see its user's guide for information on disabling the power management option. 18.2 Alloy Retriever 40/60/60e, and 250cs ----------------------------------------- Some problems exist between older firmware and Norton Backup. 18.3 COREtape Light QIC 80 -------------------------- Some Core International software versions may not be compatible with Norton Backup. Verify that you can restore backups made with Core International software using Norton Backup. You may want to keep the Core International software on your computer in case you need to restore old backups made with that software. 18.4 Iomega AccuTrak Read Mode ------------------------------ Norton Backup does not support reading AccuTrak tapes in the Iomega 250 QIC 40/80 tape drive at this time. 18.5 Maynard ArchiveXL 5240 (XT only), 5540, 5540e, 5580, 5580e, and 3580 (PS/2) ---------------------------------------------------------- Some 5240 drives have hardware incompatibilities. Norton Backup only supports tape drives with serial numbers starting with BB or above. Serial numbers starting with AA or AB are not supported. 19. LIMITATIONS =============== 19.1 Special Characters in Passwords ------------------------------------ You can use characters typed directly from the keyboard for passwords. If doing floppy, DOS path, QIC 40-80, AccuTrak, or IDE backups, DO NOT enter characters in your password by holding the Alt key and typing a three-digit number on the numeric keypad. If you use these special characters in a password, you must use Norton Emergency Restore on the Norton Desktop Fix-It Disk or Norton Backup for DOS to restore your backup set. 19.2 Logging Drives ------------------- If you receive a message that Norton Backup for Windows cannot log a drive because it contains too many directories, you can work around this problem as described below. If the drive is a local drive (as opposed to a network drive), use the DOS SUBST command to map the directory you want to back up to a new drive letter. For example, to substitute the drive letter F: for the directory E:\SOFTWARE\DOS, type: SUBST F: E:\SOFTWARE\DOS If the large drive is a Novell NetWare file server, use the MAP command with the ROOT option to map a drive letter to a subdirectory on the volume. For example, to map the drive letter G: to a network directory called SERVERA\VOLUME1\PATHNAME, type: MAP ROOT G:=SERVERA\VOLUME1:\PATHNAME If you experience problems using the MAP ROOT command, see your Novell documentation. If you receive a message that Norton Backup for Windows cannot log a drive because it contains too many files in a single directory, the only work around is to reduce the number of files by moving them to another directory if possible. -----End of Readme-----
