hi
i need to make some scripts:
1) a script that will add an zip archive each week to a tape.
2) a script that will tell when there is no room on the tape to put archives
3) a script that will search/extract a specific archive from that tape, when requested.

can you help me, please ? i'm quite a newbie on scripting. I tried 2 times for script no 1), but none of it seems to work right because when i try to extract, nothing is where it sould be or cannot be extracted. These are my scripts:

counter - is a file in my scripts directory where i store the backup track number on tape
mailul - is a file in my scripts directory where i store mail body to be sent

TRY no 1:

#!/bin/sh
#-- Declarare variabile----------------------------
data=`date +%d-%m-%Y`;
cale=/BACKUP;
src=/home/journaling/Maildir/cur
t=`cat counter`;
num_file=$data-$t

#-- Arhivare ------------------------------------
/usr/bin/zip -r -P password /BACKUP/$num_file.zip $src
count=0

#-- First time backup ----------------------------
if [ $t -eq 1 ]; then
echo " S-a creat arhiva $num_file.zip " >> $cale/mailul;
echo " Initializez primul backup pe banda " >>$cale/mailul;
mt -f /dev/st0 tell;
nice -19 dd if=$cale/$num_file.zip of=/dev/nst0;
mt -f /dev/st0 weof 1;
>counter;
echo "1" >> counter;
echo " In data `date +%d-%m-%y` ,ora `date +%T` backup created " >> $cale/mailul
#-- Next time backup ----------------------------
else
mt -f /dev/nst0 eod;

echo " In data `date +%d-%m-%y` ,ora `date +%T` backup $t created on tape " >> $cale/mailul
(( t += 1 ));
mt -f /dev/st0 weof $t;
>counter;
echo "$t" >> counter;
fi

#-- Send mail, create log -----------------------------------
cat $cale/mailul| mail mymail@mydomain -s "Journaling BACKUP"
cp $cale/mailul $cale/log-$num_file

#-- empty mail body ----------------------------------------

cp $cale/mailul $cale/log-$data
