I created the following script that works. This is only the first part of the script to save space.
# This script backs up data by copying data to a directory on an
# external usb hard drive, corresponding to that day of the week
date '+ %w' > DTE
WDY=`grep . DTE`
MD=1
TU=2
WD=3
TD=5
FD=5
ST=6
SU=0
if [ $WDY -eq $MD ]
then
mount /dev/d45050 /EXTBCK
cd /usr/ims1
ls /EXTBCK/MONDAY > FLETST
if test -e /EXTBCK/MONDAY
then rm -r /EXTBCK/MONDAY/*
fi
cp -r /dir/subdir/*.* /EXTBCK/MONDAY
umount /dev/d45050
exit
else
exit
fi
As a substitute for the weekdays, I want to create a directory on the backup device equal to the current date, ie 24Jun09, using the following script.
DAY= date '+%d%b%y'
mkdir /EXTBCK/$DAY
My intention is to then copy the data to these directories instead of weekdays
However, it does not create a directory, but gives an error, file already exists error 17
Can it be done?

Hi guys. Don't worry I came right with the following script:
mount /dev/d45050 /ARCHIVE
mkdir /ARCHIVE/`date +%d%b%y`
cp /dir/subdir/* /ARCHIVE/`date +%d%b%y`
umount /dev/d45050

I am creating an archive on a usb hard drive by copying the files with the cp command into a directory equal to the current date. I want to build in a switch that will overwrite the oldest directory as soon as the disk runs out of space. Can that be done automatically?

archive
ARCHIVE(8) System Manager's Manual ARCHIVE(8)
NAME
archive - Usenet article archiver
SYNOPSIS
archive [ -a archive ] [ -f ] [ -i index ] [ -m ] [ -r ] [ input ]
DESCRIPTION
Archive makes copies of files specified on its standard input. It is normally run either as a channel feed under innd(8), or by a script
before expire(8) is run.
Archive reads the named input file, or standard input if no file is given. The input is taken as a set of lines. Blank lines and lines
starting with a number sign (``#'') are ignored. All other lines should specify the name of a file to archive. If a filename is not an
absolute pathname, it is taken to be relative to /var/spool/news.
Files are copied to a directory within the archive directory, /var/spool/news/news.archive. The default is to create a hierarchy that mim-
ics the input files; intermediate directories will be created as needed. For example, the input file comp/sources/unix/2211 (article 2211
in the newsgroup comp.sources.unix) will be copied to /var/spool/news/news.archive/comp/sources/unix/2211.
OPTIONS
-a archive
If the ``-a'' flag is used then its argument specifies the directory to archive in instead of the default.
-f If the ``-f'' flag is used, then all directory names will be flattened out, replacing the slashes with periods. In this case, the
file would be copied to /var/spool/news/news.archive/comp.sources.unix/2211.
-i If the ``-i'' flag is used, then archive will append one line to the specified index file for each article that it copies. This
line will contain the destination name and the Message-ID and Subject headers.
-m Files are copied by making a link. If that fails a new file is created. If the ``-m'' flag is used, then the file will be copied
to the destination, and the input file will be replaced with a symbolic link pointing to the new file.
-r By default, archive sets its standard error to /var/log/news/errlog. To suppress this redirection, use the ``-r'' flag.
EXIT STATUS
If the input is exhausted, archive will exit with a zero status. If an I/O error occures, it will try to spool its input, copying it to a
file. If there was no input filename, the standard input will be copied to /var/spool/news/out.going/archive and the program will exit.
If an input filename was given, a temporary file named input.bch (if input is an absolute pathname) or /var/spool/news/out.going/input.bch
(if the filename does not begin with a slash) is created. Once the input is copied, archive will try to rename this temporary file to be
the name of the input file, and then exit.
EXAMPLES
A typical newsfeeds(5) entry to archive most source newsgroups is as follows:
source-archive
:!*,*sources*,!*wanted*,!*.d
:Tc,Wn
:/usr/lib/news/bin/archive -f -i
/usr/spool/news/news.archive/INDEX
