#!/bin/bash # Nightly backup system for home directories and MySQL # databases for websites managed by CPanel. # Author: Kieran O'Shea # Author's Website: www.kieranoshea.com # Support: kieran@kieranoshea.com # License: GPLv2 # USAGE: Place this file inside the directory you want to # put backups in, set it as a CRON job to run and collect # backups from the site(s) you define below at a preset # time each day, or run it manually everytime you want to # take a backup. You can place an unlimited number of sites # and databases to be backed up in the variables below so # long as you follow the convention. It doesn't even matter # if your different domains are hosted in different locations # so long as they are all managed by CPanel. # Prerequisites: # - Linux box with bash shell # - wget installed # Define all the sites you wish to backup in the array below # Domain name and tld only, eg. kieranoshea.com domain=( domain1.com domain2.com ) # Define all the usernames for the above sites in the array # below - keep order consistant! user=( user1 user2 ) # Define all the passwords for the above usernames in the # array below - keep order consistant! If you log on as # reseller or root you can enter the same password in # every array position, but none the less they must be filled. pass=( pass1 pass2 ) # Number of databases in each domain above - keep order # consistant. If you don't wish to backup any databases # for a particular domain, or don't have any for it, place # a 0 in it's position in the array. no_of_db=( 3 1 ) # Database names, exactly as they are in CPanel, in the order # that the domains appear. You may like to log into CPanel # manually and check your database names before filling this # variable in. Number of db names here must match the above # variables also! Eg. all dbs in domain 1 followed by all # dbs in domain 2 etc. You DO NOT need to enter any database # names below for a domain if you have placed a zero for it # in the array above databases=( domain1_datebase1 domain1_datebase2 domain1_datebase3 domain2_datebase1 ) # Thats all folks, save the file, CHMOD it to be executable # by the user who will run it, and you are all set. # Do not edit anything below this point! echo echo "-----------------------------------------------------------------" echo "Kieran's nightly backup system started" echo "-----------------------------------------------------------------" echo "" echo "-----------------------------------------------------------------" echo "Creating a directory in your backup path for tonights backup..." echo "-----------------------------------------------------------------" FOLDER="$(date +%d-%m-%Y)" mkdir $FOLDER cd $FOLDER echo "-------" echo "Done!" echo "-------" echo "" echo "-----------------------------------------------------------------" echo "Creating a directory for every domain to be backed up into..." echo "-----------------------------------------------------------------" count=${#domain } i=0 while [ "$i" -lt "$count" ] do mkdir ${domain[$i]} let "i = $i + 1" done echo "-------" echo "Done!" echo "-------" echo "" echo "-----------------------------------------------------------------" echo "Backing up MySQL databases..." echo "-----------------------------------------------------------------" overall_db_count=0 count=${#domain } i=0 while [ "$i" -lt "$count" ] do cd ${domain[$i]} mkdir databases cd databases start_point=$overall_db_count # start point for iterating over the array of db names let "end_point = $overall_db_count + ${no_of_db[$i]}" # end point to stop iterating (always the overall count!) n=$start_point while [ "$n" -lt "$end_point" ] do wget http://${user[$i]}:${pass[$i]}@www.${domain[$i]}:2082/getsqlbackup/${databases[$n]}.gz let "n = $n + 1" done let "overall_db_count = $overall_db_count + ${no_of_db[$i]}" # increase the overall count to keep a tally cd .. cd .. let "i = $i + 1" done echo "-------" echo "Done!" echo "-------" echo "" echo "-----------------------------------------------------------------" echo "Backing up home directories; this make take some time..." echo "-----------------------------------------------------------------" count=${#domain } i=0 while [ "$i" -lt "$count" ] do cd ${domain[$i]} wget http://${user[$i]}:${pass[$i]}@www.${domain[$i]}:2082/getbackup/backup-${domain[$i]}-$FOLDER.tar.gz cd .. let "i = $i + 1" done echo "-------" echo "Done!" echo "-------" echo "" echo "-----------------------------------------------------------------" echo "All backup tasks completed.

¿Qué es una infraestructura virtual? Una infraestructura virtual permite compartir los recursos físicos de varias máquinas en toda la infraestructura. Una máquina virtual permite compartir los recursos de un solo ordenador físico entre varias máquinas virtuales, para lograr la máxima eficiencia. Los recursos se comparten entre varias máquinas virtuales y aplicaciones. Las necesidades empresariales son el factor en función del cual se rige la asignación dinámica de los recursos físicos de la infraestructura a las aplicaciones, incluso a medida que van evolucionando y cambiando tales necesidades. Podrá combinar los servidores x86 y los recursos de red y almacenamiento para crear un pool unificado de recursos de TI que las aplicaciones utilicen cuando y donde los necesiten. Esta optimización de recursos da lugar a una mayor flexibilidad en la organización y reduce los costes operativos y de capital. Una infraestructura virtual consta de los siguientes componentes:Hipervisores instalados directamente sobre el hardware para hacer posible la virtualización de todos los ordenadores x86. Servicios de infraestructura virtual, como la gestión de recursos y el backup consolidado a fin de optimizar los recursos disponibles entre las máquinas virtuales.Soluciones de automatización que proporcionan funciones especiales para optimizar un proceso de TI concreto, como el aprovisionamiento o la recuperación ante desastres. Desvincule el entorno de software de su infraestructura de hardware subyacente para poder agregar varios servidores, infraestructura de almacenamiento y redes a los pools de recursos compartidos. Después, proporcione estos recursos dinámicamente, de manera segura y fiable, a las aplicaciones conforme los vayan necesitando. Este enfoque pionero permite a nuestros clientes utilizar los servidores estándar de bajo coste como componentes básicos para la creación de un datacenter que se optimiza automáticamente y ofrece los máximos niveles de utilización, disponibilidad, automatización y flexibilidad.
