writting a backup shell script


hi, i want to write a bash shell script to backup my cvs source code.

i have no idea to make it improving since i dunno how to write a bash script.

here is my starting of my script.

#!/bin/sh
date=`date -I`
tar cvfz cvsroot-$date.tar.gz /usr/cvsroot/

can u help me to tar my cvsroot-$date.tar.gz into directory /mnt/MIS ??
and also, i wish to backup my data for a week, then, the script will delete data after a week. and start to generate the backup file for a subsequent new week.


the algorithm will be like this.

for(day=monday; day<sunday; day++){
//monday
if(day == monday){
if(no storage for last monday)
backup data for monday
else{
delete the storage for last monday
backup data for monday
}
}
//tuesday
if(day == tuesday ){
if(no storage for last tuesday)
backup data for tuesday
else{
delete the storage for last tuesday
backup data for tuesday
}
}
//.......the same thing goes for wed, thurs, fri, sat and sun..

}

i will later cron it for daily activity...

thanks...

Doubt anyone will write your script for you. So if you know the functional outline of what you want to do, read this. And might as well put #!/bin/bash even though sometimes /bin/sh -> /bin/bash
