# Original script by Robert Shingledecker for John Andrews Damn Small Linux
# October 2003
#
# rapidweather version 4, dated February 2, 2004
# Modified by rapidweather to use a hard drive  partition for the backup/restore files.
# Useful for machines without a USB memory stick.
# Requires a partitioned hard drive, or a second hard drive.
# Can backup MozillaFirebird and your other files of almost any size.
# Place this file on a floppy by itself, mount the floppy in DSL to run.
# Put your own filetool.lst in the root directory of the Linux OS in your backup/restore partition.
# This partition will become the /storage directory:
# This script will create the /storage directory in the DSL filesystem for backup/restore.
# carefully modify this file to mount  the /Storage directory on the  partition you want to use. 
#
# Here is the partition I am using: 
# using /dev/hda11, a ext2 linux partition. 
# put this in line 40 below:
# 
# A simple script to save/restore configs, directories, etc defined by the user
# in the file filetool.lst
# Upon first successful run of this script a default filetool.lst will be
# copied to the BACKUP_DEVICE. Then the user can control which files/dirs will
# save/restore
#
HOME=/home/damnsmall

# Because it might exist, I am going to un-mount and remove the Storage directory
# so this script can proceed normally.
sudo umount /storage
sudo rmdir /storage

# Functions
# Get mounted backup device for save/restore of configs, etc.

# For a restore/backup I have to create the Storage directory within the DSL filesystem.  
sudo mkdir /storage
# Then, I'll mount it.
