backup Bash script
Roger
(or other folders/files) that you want. i wrote it because i only have a
need to only back up certain files repetiously rather than use a tape
device (which is dog slow) to backup 200mb - 2 gigs of data.....i'd rather
just buy an entire seperate hdd to clone it to! there is a another bash
script very well written but is mainly for tape drives <bummer>
what would be nice is a seperate newsgroup for bash, but the only one i've
come across is gnu.bash.bugs and some other programming groups. since i
use mandrake constantly, decided, 'why not give back to the mandrake
community eh???'
directions are the usual, copy/edit/save it to file with an editor. chmod
+x filename to make it executable.
here it is:

#
# Description of Backup Bash Script:
# To do only an incremental backup of config files and other necessary files
# using
# a bash script. Maybe could also be automated by directly linking
# in as a daily/weekly/monthly cron job! This script was only intended to
make
# minimal sized backups since there are other harddrive utilities that will
# backup entire partitions with greater ease and conservation of space,
# including tape backup options.
#
# Some things that would be nice:
# 1) To have a seperate file list that will list the files or directories to
# backup. This may also easily create one archive instead of multiple
# archives(?). Although I like being able to decompress the *.tar.gz
files
# that I want to preveiw and backup. (One file can get quite large!)
#
# Why the username added to the archive filename?
#
# Obvious. A host computer may have more than one user using the backup
script.
# Adding the username to the filename enhances readability including the
# following 'Why the date?' reason!
#
# Why the date added to the archive filename?
#
# Because I don't trust computers. If by chance, I copy my archive to
another
# HDD or other media, the computer may redo the dates (as in MS Windows
case).
#
# Why not a recovery routine?
#
# I do not plan to have a restore option since 'ark' is nice and neat.
# With the gui of 'ark', one can easily preveiw their text files w/o
untar'ing!
# To unzip and untar with 'ark' is easily done, but to zip/tar on routine
# backups is a hinder with ark.

try comp.unix.shell
and i just recently rewrote my backup script
here here we go.
>--------------begin of file------------------------
#!/bin/bash
#/home/faux/shell/BAckUP mounts a partition
#called /BACkUP so that incase i do something like rm -fr /
#that data will still be safe
#see the second script in this post for it
#the partition is unmounted by cron latter
#for some reason if i try to unmount the partition
#inside the scirpt it gives a error and lots of bad things
#can happen
#
#
#these scripts runs once a day in cron
