Drive backup Images
03-01-2008
#! /bin/bash
#
# OS: Unix/Linux
# Name: hda-to-hdc
# Ver: 03/01/08
# Purpose: Full disk image copy
# By: Jan Zumwalt - www.neatinfo.com
#
# REMARKS:
# I use the fllowing echo commands that some may not be
# familure with...
#
# -e = enable interpretation of backslash codes
# -n = disable newline at end of line (i.e. user input prompt)
# \t = tab
#
# This program uses (and offers to create) $HOME/logs/backup.log
# The dd command is used; where "if" stands for "in file"
# and "of" is the "out file". Therefore "if" is the source
# drive and "of" is the target drive.
#
# The source and target are designated by hda, hdb, hdc, hdd, etc.
# hda thru hdd are the four drives that may be connected to the
# computers IDE cables. Numbers behind these designations are the
# partitions. So, hda1 is the first drive and the first partition.
# hdb3 would be the second drive and the third partition.
#
# This program can also be used for other drives and cables such
# as SCSI or SATA. It has been several years since I used it for
# these and so I did not risk giving an example that may be
# outdated or have an error.
