Assuming for the moment that the system has an IDE hard drive, the simplest way is to add a second IDE drive, and use Norton Ghost to duplicate the drive, by booting from a DOS/Win95/Win98 diskette. Do not attempt to change the partition size, as this function of Ghost is not supported.
If you have a SCSI system, then you can use the same process if:
1 you have a DOS driver for the SCSI host adapter,
2 you have a disk with the same number of heads and sectors per track.
3 you know how to install a scsi disk
There are ways to do this using SCO unix, read the installation manual about adding a second hard drive, run mkdev hd, but skip the divvy section, and use "dd" to copy /dev/hd0a to /dev/hd1a
You could also purchase Microlite Edge from
Home of Microlite BackupEDGE / RecoverEDGE, and then use its backup and recovery features.
