Answer 1

Create somewhere a script to make your rolling backups, like this (untested, but should work):

#!/bin/bash

BKPDIR=dailbackup  # You must use absolute path here
DB=finaldb
USERNAME=myusername
PASSWORD=mypassword

BKPFILE=${BKPDIR}/`date +%Y-%m-%d`/final_db_`date +%H`.sql

# Create backup
mysqldump --user=${USERNAME} --password=${PASSWORD} ${DB} | gzip -c > ${BKPFILE}

# Remove older backups (> 7 days),
# unless you want to run out of drive space
find ${BKPDIR} -mtime +7 -print0 | xargs -0 rm -rf

Then setup this script to run as an hourly cronjob:

crontab -e
