Создание архивной копии MySQL

#!/bin/sh

# This script will backup one or more mySQL databases
# and then optionally email them and/or FTP them

# This script will create a different backup file for each database by day of the week
# i.e. 1-dbname1.sql.gz for database=dbname1 on Monday (day=1)
# This is a trick so that you never have more than 7 days worth of backups on your FTP server.
# as the weeks rotate, the files from the same day of the prev week are overwritten.
