SEPTEMBER 1997 - MIRROR IMAGE BACKUP/RESTORE - BETA 9.05a

This BETA image backup utility is NOT FOR GENERAL USE. It is only available
to owners of Valitek PSTý who wish to test this software for proper operation.
This software has not undergone thorough field testing. So it is possible 
that it contains undetected bugs. Below is a list of general notes which 
should be studied before attempting to use this image backup program.

NOTE: Be certain to test the connection to the drive using the SYSTEM TEST/
VERIFY CONNECTION option before starting a backup. Also, be sure your DAT
tapes have been partitioned before starting a backup.

1) To run this software you must boot your computer using a DOS 6.xx or
   Windows 95 start-up disk.

2) Pay attention to the hard-disk cylinders, heads, sectors/track, and 
   capacity numbers when they are displayed by the software. If they differ
   a lot from what you expected you should try to find out why there is a 
   discrepancy. There are a variety of hard-disks, controllers, and
   interfaces. Every combination has not been tested. 

3) This software should work correctly regardless of what operating system
   is on the hard-disk being backed up provided that the basic hardware is
   DOS compatible standard PC clone hardware.

4) This software treats each backup as a complete unit. You can not restore
   individual files from this image backup. It is recommended that critical
   backup applications be duplicated using the standard Valitek File Backup
   software version 3.Xx if possible.

5) This backup method preserves the contents of the Slack Area, Deleted
   Files, Deleted Directories, Boot Sector, Partition Table, unused
   sectors and clusters.

6) Whenever possible the restore destination hard-disk should be configured
   identically to the source hard-disk. Minimally, the number of heads and
   the sectors-per-track must be the same. You may be able to achieve a
   successful restore if the destination drive has more cylinders than the
   source drive. The destination drive must be at least as large as the drive
   which was backed up. Certain characteristics of the destination drive may
   be modified by changing the DRIVE TYPE in your computer's CMOS SETUP
   options.

7) The backup approach used by this program is to make a copy of all physical
   sectors of a physical drive unit. Each physical drive unit must be backed
   up individually. Your computer will generally designate your drive units
   as 0 and 1. Your C: drive will generally be located somewhere on physical
   drive 0. But it is not necessarily the only logical partition on unit 0.
   Unit 0 may, for example, also contain D: E: and F:.

8) Generally, all of the sectors on a disk should be backed up when doing an
   image backup. A partial backup of specific sectors is usually not very
   useful. However, if you do require a partial backup you can accomplish this
   by tagging specific sector groups with the 'T' key and pressing F5.

9) The Image Backup (ver. 9.XXx) and File Backup (ver. 3.Xx) use compatible
   tape formats, but they perform entirely different operations. If the backup
   created with this Image Backup program is mistakenly restored using the
   File Backup software it will create files on your disk with names such
   as ø0008000, or ø00A8000, rather than writing the information as raw
   sector data.

10) The VERIFY TAPE option in the MAIN menu is still useful to verify the
   integrity of a backup, even an Image Backup.
