[ubuntu-uk] Simple backup script

[Chris Rowson]

I promise to stop spamming the list now! Final draft.

I know the email component should be put into a function but I'm a bad man
and didn't do it!

Just added an extra section that checks to make sure that tar didn't throw
an error code for some reason when it exited.

BACKUPDIR="/home/username/backup"
WHATTOBACKUP="/var/www"
SERVERNAME="servername"
BACKUPADMIN="email at domain.com"
MESSAGE="/tmp/message.txt"

if [ -d $BACKUPDIR -a -d $WHATTOBACKUP ] *#make sure the source & dest dirs
exist*

        RESULT=$? *#grab the tar exit code*
        if [ $RESULT -eq 0 ] *#tar will return non-zero if an error occurs.

        then

               * #then remove anything over 7 days old*
                find $BACKUPDIR/*.tar.gz -mtime +7 -exec rm -f {} \;
