Backup VM Virtualbox в Сentos PDF Печать E-mail

Скрипт резервного копирования виртуальных машин Virtualbox в Сentos.

 

Для резервного копирования написано не мало скриптов. Из всего что мне попадалось я выбрал данный скрипт и подредактировал его под свои условия.




Исходные данные:

Сервер Centos 6.0 (x64)

VirtualBox

виртуальная машина с названием w2003

скрипт автоматического запуска и управления виртуальными машинами (статья)


Для остановки старта виртуальной машины используется команды:

/etc/init.d/vboxcontrol start-vm w2003
/etc/init.d/vboxcontrol start-vm w2003

 

Скрипт останавливает виртуальную машину. (если у вас несколько вирт. машин, допишите стоп и старт всех ваших вирт. машин)

Автоматически находит все виртуальные машины.

Делает резервную копию вида backup_w2003-20120731.tgz и лог файл, в директорию /backup/VMs/root/archives

 

#!/bin/bash
##
## Destination of backup files
## Script won't run if directory doesn't exist
/etc/init.d/vboxcontrol stop-vm w2003
echo "STOP - w2003"

BACKUPDEST="/backup/VMs/${USER}"

## How many days a compressed version will be left on server
DAYS_TO_KEEP_TAR=7

## Exempt VMs - Place each VM with a space seperating them
## Example:    ( linux winxp win7 ) or
##       ( "Ubuntu 8.04" "Windows XP" ) or
##       ( None )
## More here: http://www.cyberciti.biz/faq/bash-for-loop-array/
## Run Command to find list of VMS:
## VBoxManage list vms | grep '"' | cut -d'"' -f2 2>/dev/null
EXEMPTION_ARRAY=( None )

## No need to modify below here
IFS=$'\n'
HOST=`hostname`
DATEFILE=`/bin/date +%Y%m%d`
VMLIST=`VBoxManage list vms | grep '"' | cut -d'"' -f2 2>/dev/null`
